摘要：
A single-feed dual-band circularly polarized (CP) microstrip antenna operating in Ka-band is proposed. The lower band and the upper band are excited by Archimedean spiral radiator. The main polarization mode of two resonant frequency (29 GHz and 38 GHz) are left-hand circular polarization(LHCP). The antenna achieves a small frequency ratio(1.31). The overlaps between -10 dB impedance bandwidth and axial ratio 3-dB bandwidth are 1.3 GHz(4.5% at 29 GHz) and 2.4 GHz (6.3% at 38 GHz).
