Abstract
Separated turnstile Antenna can provide saddle-shaped and hemispherical patterns. Its ability in making the arbitrary earth covering pattern has provided a lot of applications in small LEO satellites. In this article, the proper pattern for separated turnstile antenna which is mounted on a small LEO satellite, is synthesized and shaped. Wired model of separated turnstile antenna is analyzed by Moment Method and its gain pattern, polarization and input impedance are calculated. Ability of dual band operation of this antenna has been investigated in the paper and a dual band separated turnstile antenna bas been designed for the satellite. Also, Effects of antenna geometrical parameters on its pattern have been researched and calculated in the paper.
