Dual-wideband and dual-polarized shared aperture antenna

Abstract

Dual-band dual-polarized (DBDP) antennas can offer a lot of advantages for Remote Sensing applications. The dual-band operation of the antennas can provide frequency diversity to such sensors. Dual-polarization operation can enhance the information content by providing two co-polarization and two cross-polarization back scatter information. By sharing the same antenna aperture, the overall size and weight of the array can be reduced. Microstrip antenna is usually selected for such work for its low profile and simplicity in fabrication. Therefore, a number of DBDP shared-aperture antenna arrays based on microstrip patch technology have been proposed and studied. The typical configuration of DBDP array includes perforated patches and patches [1,2], interlaced slot/dipole with patch[3-5]. © 2012 IEICE.
