В книге рассматриваются базовые принципы, которыми следует руководствоваться при конструировании и изготовлении радиолюбительских антенн. Даны описания практических конструкций антенн КВ и УКВ диапазонов, а также рассказывается об основах компьютерного моделирования антенн. Basic Antennas is a comprehensive introduction to antennas-basic concepts, practical designs, and details of easy-to-build antennas. You ll learn how to make antennas that really work! This book will provide a foundation in antenna theory and design necessary for anyone undertaking more advanced topics such as those presented in The ARRL Antenna Book. Includes: Dipole Antennas, Antenna Impedance, Transmission Lines, Practical Two Element Arrays, Wideband and Multiband Antennas Reflector Antennas, Yagis for HF and VHF, Loop Antennas, Antennas for Microwave Applications, Vehicle Antennas, Antenna Measurements, Plus, an Introduction to Antenna Modeling...and much more!
