Circularly Polarized Array Antennas for Synthetic Aperture Radar
The L-band of LHCP and RHCP array antenna for circularly polarized synthetic aperture radar(CP-SAR)has been developed using simple corner-truncated square-patch elements.The corporate feed design concept is implemented by combining a split-T and a 3-way circular-sector-shape power divider to excite circularly polarized radiation.The fabrication of both antennas based on the simulation using the method of moment(MoM)gives a good circular polarization.Impedance bandwidth and 3-dB axial ratio bandwidth for LHCP are 6.1%and 1.0%,respectively,while for RHCP are 6.2%and 1.0%,respectively.The full antenna(four panels),will be installed on an Unmanned Aerial Vehicle(UAV)JX-1 in Center for Environmental Remote Sensing,Chiba University.In the future,CP-SAR is expected to improve the characteristics of conventional SAR system,especially to extract some new physical information on the earth surface.
