A deployable bottom fed conical log-spiral antenna for CubeSat applications

The requirements for deployable antenna systems on micro-satellites, specifically on the CubeSat platform, are ever changing. This thesis will address the possible antenna systems that would best be deployed on a CubeSat, with the major focus on the conical log-spiral antenna (CLSA) due to its frequency independent characteristics. The antenna design will then go beyond the published works of the CLSA to introduce a new feeding concept, a bottom fed CLSA. Necessity for this feeding rises out of limited deploying capabilities of the CubeSat platform, which is significantly smaller than the proposed antenna due to frequency constraints. A scaled prototype of the bottom fed CLSA is investigated and optimized. The scaled antenna system is constructed and the results are presented.
