Book Synopsis Super-Dipole Antennas by : Edward J. Shortridge
Download or read book Super-Dipole Antennas written by Edward J. Shortridge and published by Dog Ear Publishing. This book was released on 2018-03-22 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Super-Dipole Antennas” is a book that introduces a completely new “Unified Broad-Banding Method”. This method primarily consists of the use of a 1/2 wavelength Dipole, which is fed with a 1/4 (or shorter) wavelength resonant line. The amount of coupling between these two components is greatly reduced and controlled to produce a wide SWR bandwidth. This Broad-Banding Method is referred to as “Critically-Coupled Broad-Banding”. There are many different configurations that are possible and these are presented in a logical sequence, showing how each has evolved from the previous one. Some use “Low Impedance Coupling”, while others utilize “High Impedance” and both can achieve low SWR bandwidths. Most all of the configurations are adaptable to the various radio Amateur bands, from 160m to above the 6m band. Some utilize wire radiators, while others at the higher frequencies, utilize aluminum tubing. Large numbers of antennas are presented covering most all of the wider Amateur radio bands where Broad-Banding is most desirable. The completely new and unique configurations introduced will completely change the perception of how antennas are Matched and Broad-Banded. Many of the configurations are very simple and easy to understand. Most have been reduced in complexity, cost of materials, and can readily be assembled and these are referred to as “Super-Dipole Antennas”. Other methods of Broad-Banding are also presented, which have unique advantages, while some others have Multi-Band capabilities. Almost all of the configurations presented include charts showing how the Far-field gains and coaxial losses vary across each of the bandwidths, giving a good perception of the efficiency on each band. Each antenna configuration has been carefully computer-modeled, making certain that all of the critical requirements are taken into account and checking the consistency of results, thus giving an assurance of good modeling accuracy. This book has been written to purposely keep it simple, point out the pertinent details, make comparisons between different antennas, in the simple straightforward manner, while avoiding any complicated formulas. It is meant to be a tutorial on Broad-Banding, along with the catalog of practical antenna configurations in order to encourage further interest, imagination and experimentation.
Book Synopsis Super Max-Dipole Antennas by : Edward J. Shortridge
Download or read book Super Max-Dipole Antennas written by Edward J. Shortridge and published by Dog Ear Publishing. This book was released on 2017-04-19 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: A previous book titled “Super-Dipole Antennas”, which was written by this author, introduced a completely new Unified Broad-Banding Method. This method primarily consists of the use of a 1/2 wavelength Dipole, which is fed with a 1/4 (or shorter) wavelength resonant line. The amount of coupling between these two components is greatly reduced and controlled to produce a wide SWR bandwidth. This Broad-Banding method is referred to as “Critically-Coupled Broad-Banding”. This new book, titled “Super Max-Dipole Antennas” is a continuation or addition to the previous book and primarily presents Inverted V and Horizontal antennas in the 75-80 and 160m bands, which are some of the widest HF bands. Early chapters reintroduce the “Unified Broad-Banding Method”, presenting Inverted V antennas, with each of the possible “S” Broad-Banding configurations presented at various antenna heights, with a few newer configurations being presented. A totally different Broad-Banding method, which uses “Dual Inverted V” antennas, which can produce very low SWR bandwidths at all antenna heights, is then presented. Some of these were previously presented but these are new or improved versions. The latter chapters present some completely new Broad-Banding configurations utilizing “Dual Inverted V” radiators, which in itself creates Broad-Banding but by adding one of several “Critical- Coupling” configurations, “Double Broad-Banding” can be achieved. This arrangement can produce SWR bandwidths at or below an SWR of 1.5/1 across the entire bandwidth at any and all antenna heights. This appears to be a notable achievement, not occurring often. These new and unique configurations introduced will completely change the perception of how antennas are matched and Broad-Banded. Many of the configurations are very simple and easy to understand. Most have been reduced in complexity, cost of materials and can readily be assembled and these are referred to as “Super-Dipole Antennas”. Throughout this book configurations presented include charts showing how the Far-field RF gains and coaxial losses vary across each of the bandwidths, giving a good perception of the efficiency on each band. All of the antennas throughout this book have been configured with an efficiency in mind and those antennas that have higher losses are scrutinized rigorously and the true performance specifications are shown, whether they are good or bad.

Book Synopsis Super Multi-Band Antennas by : Edward J. Shortridge
Download or read book Super Multi-Band Antennas written by Edward J. Shortridge and published by Dog Ear Publishing. This book was released on 2017-03-29 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two previous books titled “Super-Dipole” and “Super Max-Dipole” Antennas were written by this author, thereby introducing a completely new “Unified Broad-Banding Method”. This method primarily consists of the use of a 1/2 wavelength Dipole, which is fed with a 1/4 (or shorter) wavelength resonant line. The amount of coupling between these two components is greatly reduced and controlled to produce a wide SWR bandwidth. This Broad-Banding method is referred to as “Critically-Coupled Broad-Banding”. This new book, titled “Super Multi-Band Antennas” is a continuation of the previous book, where Broad-Banding is taken to an extreme and Dual-Band antennas can be configured either on an adjacent band or those that might have a much greater 2 to 1 frequency separation. Early chapters of this book reintroduce the “Unified Broad-Banding Method”, presenting Horizontal antennas with superb SWR bandwidths and then showing Dual-Band versions with many different band combinations from 60m on up to 450 MHz, using either wire or tubing. Single band Folded-Dipole configurations using tubing or Ladder-line/Window-line are shown to produce extremely low SWR bandwidths. Inverted “V” Dual-Band antennas, with many band combinations allow for easier antenna mounting. Both Vertical and Horizontal Single-fed, Dual-Band Quad antennas have a limited bandwidth but when each individual 1/2wL section is fed, these antennas are classified as a “Prismatic Polygon” and thereby achieve far greater bandwidth, achieving it in a totally different manner from the “Critically-Coupled” method. There are many versions of Quad, Triangular, Pentagons and Hexagon Polygon antennas and all of their Multi-radiators must be fed. Some can cover from 30 to 10m, while others can cover from 144 to 450 MHz, allowing all services within the bandwidth, including the Amateur Radio services to use these antennas. This book presents large numbers and a variety of antennas and it also provides a path of the evolution from one type of antenna to another, providing detailed performance. Many thanks again to Eugene Belton and Dale Parfitt for their dedicated hard work, which without; these books would not have been possible. Surely you will be pleased with the extent of information provided, which covers important details.

Download or read book Antenna Measurements at Super-high Frequencies written by Iurii Vasil'evich Shubarin and published by . This book was released on 1966 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the first chapter there is given a basis and account of the method of measurement of basic parameters of shf antennas, typical circuits applied here and also methods of processing and estimating error of measurements. In the second chapter seven laboratory projects of antenna practical work are described. The practical work permits us to subject to graphic experimental proof a series of very important theoretical propositions expounded in the course on shf antennas; to illustrate the method of measurements of parameters of antennas with practical examples; to acquaint students with the design and certain methods of engineering calculation of basic types of shf antennas. Description of every practical project contains information on designing the proper laboratory installation, assignment for conducting experiments and calculations, and also a list of materials which should be presented in the report on the finished project. Selection of problems for practical work and the character of assignments are aimed at development in students of a desire for independent investigation. Everywhere where possible, comparison of theory with experiment and estimation of its accuracy are required. In the third chapter there is given a description of a series of samples of typical equipment applied during shf antenna measurements. This facilitates home preparation of students for doing assignments of antenna practical work and can serve as a brief reference book on frequently used equipment. (Author).
