Scientific satellite antenna
Abstract
The paper studies the effects of inclination angle of a canted turnstile antenna consisting of quadrupole whip antennas fed with circularly polarized radiation for use on scientific satellites. It was shown that an omnidirectional radiation pattern for such an antenna could be obtained by setting the distance between antenna feed points to about lambda/2 since the satellite diameter is about approximately equal to one wavelength (lambda) at UHF and by setting the inclination angle to theta between 90 and 180 degrees. A 1/4 scale and a full scale model of satellites were used in making the measurements and results were applied to SRATS-F and CORSA-F.
