| description | In this paper, a wideband circularly-polarized
spiral antenna is proposed to be used for CubeSat application.
The antenna covers two of CubeSat frequencies; the S-band
(2.2 GHz) and X-band (8 GHz). The proposed antenna belongs
to the wideband and frequency-independent antenna category,
which are known to provide a constant radiation pattern,
impedance and polarization throughout the whole bandwidth.
The performance of the spiral is compared in two different
conditions; in free space and above a ground plane with a
separation distance of λ/4 at the operating frequency of 2.2
GHz and 8 GHz. The spiral above the ground plane exhibits a
unidirectional radiation and higher gain with an increase of
26.6% (2.2 GHz) to 34.6% (8 GHz) than the free space spiral.
Moreover, the return loss also managed to stay within the ideal
limit of S11<-10dB (-19.528 dB at 2.2 GHz, and -21.92 dB at 8
GHz) and exhibits circularly-polarized radiation with low axial
ratio < 3 dB (0.78 dB at 2.2 GHz, and 0.89 dB at 8 GHz). |
