Summary:
Polarization loss of wireless communication system is caused by a mismatch of polarization between incident wave and receiving antenna. In order to compensate a polarization loss of circular polarization system, tunable circular polarization antenna is proposed. The polarization of the proposed antenna is tuned by using a reflection type phase shifter on sequential rotation feed (SRF) microstrip array. The axial ratio of polarization can be converted up to 3.7 dB for two orthogonal tilt angles in 9.5 GHz. Thus, polarization loss factor (PLF) is compensated by polarization matching.
