Abstract

The paper investigates the use of CubeSat body as an UHF antenna for 435 MHz band. Since the lowest characteristic modes in 1U CubeSat become significant around 1 GHz, a set of four arms is developed to decrease this frequency and realize compact antenna that can be enclosed within in a sphere of 0.3 λ diameter. The antenna does not rely on any deployment mechanism, significantly increasing reliability of the satellite. Two use-cases are investigated: a linearly polarized with omnidirectional pattern and a bidirectional circularly polarized. Both offer broad beams with 1.6 dB gains, which is comparable to much larger deployable CubeSat antennas.
