Low Profile LHCP GNSS-R Array Antenna for the Killick-1 2U CubeSat
A deployable array antenna for the Killick-1 2U CubeSat equipped with a Global Navigation Satellite Systems Reflectometry (GNSS-R) payload is designed and tested. Considering the physical constraints, a low-profile array antenna consisting of six patch antennas spanned over three separate panels has been designed. To design the array antenna with lefthand circular polarization (LHCP), first, a single panel hosting two double-fed patches is designed and optimized using the Ansys HFSS software. Based on the single antenna panel, the six-element antenna array is modeled, fabricated, and tested. The test results indicate that with a 10.2 dBi gain, the proposed antenna array meets all the requirements. The proposed array antenna is a flexible and reliable solution for similar missions.
