VHF Antennas for Low-Altitude Satellites,

Abstract

Two vhf satellite antennas are discussed in depth. The first is a turnstile antenna, which is presented with theory, computer calculations, experimental results, and two novel applications. The first application solves the problem of interfering solar cell panels by combining them with the antenna. The second application puts the turnstile antenna on a boom away from the satellite to minimize interference. The second vhf satellite antenna presented has multiple elements and is designed to optimize the pattern with respect to the distance and angle from a stabilized satellite to a ground station as it passes overhead. This antenna was found to have a 3-dB improvement over the best turnstile designs. (Author)
