STUDY OF FREQUENCY INDEPENDENT ANTENNAS

Abstract

An investigation was made of frequency-independent antenn fro the point of view of designing the antennas for any radiation pattern and polarization. Solutions of Maxwell's equations were discovered which explain the theory of fr uency independent antennas. The effect of curvatur on the current distribution is strikingly demonstrated but the most remarkable feature is the incoming current wave at large distances, when the angular phase velocity of the excitation is in the direction of decreasing radius along an equiangular spiral. Solutions for periodic antennas were also obtained and extensive computations are being made. (Author)
