Directional properties of linear and v-antennas

摘要

The method for calculating directional characteristics of thin antennas with large dimensions: directional patterns, directivity, pattern factor is proposed. The analytical expressions are determined, and characteristics of metal dipoles, V-dipoles and analogous in-phase radiators are calculated. The importance of accounting the pattern factor for the estimate of a communication range is shown. The advantage of in-phase radiators is demonstrated. The possibility of an employment of the given radiators as elements of directional antennas and antenna arrays is considered.
