A dual-band deployable Cassegrain reflector antenna for Space applications

This paper presents a dual-band deployable Cassegrain reflector antenna, that operates in K-band for reception and Ka-band for transmission. The antenna achieves gain of approximately 38 dBi in K-band and 42 dBi in Ka-band. The antenna fits into a stowed volume of 2.15U CubeSat and weigh approximately 2.6 kg. The paper also demonstrates different design stages that were involved in achieving the proposed antenna system. Furthermore, the simulated system level performance calculated in CST as well as in HFSS are compared and presented in this paper.
