要約(日本語): We are developing a nano satellite, HATOSAT. In this study, we aimed to develop and prototype antennas for Store & Forward ground station which is one of HATOSAT mission, and to evaluate its characteristics. The antenna which used in this developing is a patch antenna because it can be made smaller and lighter and does not use a mechanical mechanism such as a deployment mechanism. The antenna for the Store & Foward ground station was initially simulated using FR 4, but the antenna gain was 2.5 9dBi, which is less than the target 5dBi. Therefore, it is decided to use the substrate which dielectric loss tangent is lower. Also, we will measure the axial ratio to confirm that the circular polarization is correctly emitted in the future.
