Available in PDF, EPUB and Kindle. Book excerpt: How to Build Effective Wire Antennas was written to fill the gap between building an antenna from a pattern which includes all the dimensions and those very dry fully technical books which tell you how to design an antenna from scratch with all the details but doesn't tell you how. There is sufficient technical detail, where required, for you to be able to design your own wire antenna for any frequency you like and have it work as designed. There is practical information about materials to use with a focus on keeping costs down. These are simple designs that anyone with basic tools can build and have working in a couple of hours.

Book excerpt: The contents of this book are mostly aimed at the amateur radio beginner and aspiring ones. Therefore, this book provides answers to basic questions like: What is the best HF antenna for my needs and location? What type of stand-alone antenna tuner should I use and which should I avoid? How can I hide my HF antenna from the neighbors and still get acceptable performance from it? What about lightning protection? This book will supply immediately useful answers to the above questions and many more. A properly designed and installed amateur radio HF antenna system can potentially make the humblest ham radio equipment perform like stations worth thousands of dollars. We are confident that the antenna experimenter will find the information given here priceless. Furthermore, any ham radio operator, armed with the information this book contains, will become a much better informed buyer of commercially made HF antenna systems and accessories. This special compendium edition is published in response to ham radio operators who wrote to ask that all the basic information, on and related to amateur radio HF antennas, be made available in one book instead of four, arguing that it would be more convenient. The author and publisher agree. Therefore this edition contains the complete four-book series on Amateur Radio HF Antennas published by Claude Jollet, VE2DPE.

Download or read book Automated Design and Optimization of Wire Antennas Using Genetic Algorithms written by Derek Scott Linden and published by . This book was released on 1997 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Genetic Algorithm (GA) has been used in conjunction with the Numerical Electromagnetics Code, Version 2 (NEC2) to create and optimize atypical wire antenna designs with impressive characteristics. Antenna design parameters are encoded into an ordered series of numbers and/or symbols analogous to a biological chromosome. A cost function that quantifies how well a design meets the engineer's specifications is created. The GA uses these to generate and evaluate a population of designs. The most successful designs are then promoted and mixed through mating and mutation, while poor designs are removed. This process, difficult to trap in local minima, continues until convergence criteria are met, generally yielding excellent designs with no user intervention or initial guesses. Three antennas have been optimized: a monopole loaded with a modified folded dipole, the Yagi antenna, and the crooked-wire genetic antenna. Prior study of the loaded monopole had shown hemispherical coverage was possible. The GA found an asymmetric loaded monopole with an average variation in gain over the hemisphere of only 0.4dB, confirmed by measurement. GA-optimized Yagi antennas surpassed the gain of conventional Yagis by about 1dB, improvement also confirmed by measurement. The GA designed a Yagi with a beamwidth of 50 deg -60 deg, sidelobes nearly 25dB down, and a 14% bandwidth-specifications difficult to achieve using conventional techniques. The crooked-wire genetic antenna is several wires joined in series; locations and lengths are determined by the GA. Optimization for hemispherical coverage with right-hand circular polarization (RHCP) produced highly unusual shapes unrealizable using a conventional approach. RHCP hemispherical coverage was achieved with less than 4dB variation. Measurements verify the results.

Book excerpt: After discussing the phenomenon of wave detachment and radiation within the nearfield of wire antennas in terms of fieldlines, instantaneous and time-average energy flow and Poynting vector ellipses, a new equivalent circuit is introduced which helps to describe and optimize short radiators. Numerical methods for shaping wire antennas for maximum performance are given. Parameters to be optimized are, for example, directivity and effective length. Numerous results for single and split-wire antennas with and without reflector, offering directivities ranging from 7 to 16 db, are presented. The results are also discussed in terms of nearfield properties. Methods for optimizing a combination of performance parameters such as directivity, sidelobe level and impedance are then presented, and results given. Arrays of these optimally shaped elements are combined in new backfire, Yagi-uda and LP antennas which offer surprising properties.
