Antenna Theory - Loop

A loop antenna is a radio antenna consisting of a loop or coil of wire, tubing, or other electrical conductor usually fed by a balanced source or feeding a balanced load. Within this physical description there are two distinct antenna types:. For all of the large loops described in this section, the radio's operating frequency is assumed to be tuned to the loop antenna's first resonance. Hence, self-resonant loops are most often used at higher frequencies where their sizes become manageable. Large loop antennas can be thought of as a folded dipole whose parallel wires have been split apart and opened out into some oval or polygonal shape. Loop antennas may be in the shape of a circle, a square or any other closed geometric shape that allows the total perimeter to be slightly more than one wavelength. There may be one or more additional loops stacked parallel to the first as parasitic elements , making the antenna system unidirectional with increased gain.

Updated with color and gray scale illustrations, a companion website housing supplementary material, and new sections covering recent developments in antenna analysis and design This book introduces the fundamental principles of antenna theory and explains how to apply them to the analysis, design, and measurements of antennas. Due to the variety of methods of analysis and design, and the different antenna structures available, the applications covered in this book are made to some of the most basic and practical antenna configurations. Among these antenna configurations are linear dipoles; …mehr. DE Constantine A.

There is a large body of literature for electrically-small loop receiving antennas including more recent work in demagnetization effects for magnetic materials which are used for reducing antenna size. Optimal design of loop antennas requires understanding the electromagnetic principles and is limited by the accuracy of predicting the electromagnetic parameters resistance, inductance, capacitance, effective permeability, sensitivity. Using a ferrite magnetic core greatly complicates analysis and prediction of resistance, inductance, and sensitivity as a function of frequency due to the dependence on core material properties, core geometry, and wire coil geometry upon the core capacitance is typically negligibly affected. Experimental results for the two ferrite-core loop antennas and an air-core loop antenna validate the optimal design approach with good overall agreement to theoretical prediction of resistance, inductance, and sensitivity. Discussion and comparison between air-core and ferrite-core designs demonstrate the trade-off between outer diameter, length, and mass vs. The EM Academy piers. Authors Reviewers.

Нельзя, чтобы Хейл что-то заподозрил. ГЛАВА 43 В свои сорок пять Чед Бринкерхофф отличался тем, что носил тщательно отутюженные костюмы, был всегда аккуратно причесан и прекрасно информирован. На легком летнем костюме, как и на загорелой коже, не было ни морщинки. Его густые волосы имели натуральный песочный оттенок, а глаза отливали яркой голубизной, которая только усиливалась слегка тонированными контактными линзами.
