Abstract :In this article, operational performance variations of VHF and UHF turnstile antennas widely utilized in Cube Satellites (CubeSats) are investigated according to their placement positions on 3U size platforms. Considering the utilizable space constraints in CubeSats and the volume of the orbital deployer case, a platform-integrated deployable turnstile antenna concept is applied for VHF and UHF antennas designed at 145 MHz and 435 MHz, respectively. The performances of conceptual deployable turnstile antenna designs are optimized by placing them separately in the central and edge regions of the 3U CubeSat platform. Then, their performances in the scenarios of joint use on the same platform are also investigated. The obtained results show that while the location of the antennas does not significantly affect the performances in individual placements, the performance of the UHF antenna is substantially increased in the central placement where VHF and UHF are installed on the same platform.
