Abstract:

This communication presents a low-profile circularly polarized (CP) shared-aperture antenna at C-and Ka-band for CubeSat communications. It consists of a C-band metasurface antenna and a 4×4 Ka-band magnetoelectric (ME) dipole antenna array, and only has 0.057λlow thickness. The square ring reactive impedance surface (RIS) and an irregularly shaped driven patch are meticulously designed in the C-band antenna without affecting the radiation performance of the Ka-band antenna. Meanwhile, a sequential rotation feeding network (SRFN) is adopted for the Ka-band antenna to improve the axial ratio (AR) performance. The measured results show that the overlapped operational bands (|S11| <-10 dB, AR < 3 dB) are 11.4% (6.2-6.95 GHz) for the C-band and 36.7% (26-37.7 GHz) for the Ka-band, with realized peak gains of 9.36 dBic and 17.2 dBic, respectively. The isolations of the shared aperture antenna within the two operating bandwidths are both better than 20 dB. With the excellent advantages of low-profile and dual-wideband, the proposed antenna is suitable for various communication applications in CubeSats.
