A 16 × 1-element microstrip antenna array with dual-polarized stacked corner-fed square patches as its elements is presented. This linear array fed by the coplanar feed and the slot-coupled feed for dual polarization, respectively, together with the pair-wise anti-phase feeding technique, achieves measured port isolation better than 33 dB with the maximum reaching 43 dB in the bandwidth of 9.375–9.825 GHz. The measured bandwidths of VSWR ≤ 1.5 reach 15% and 13.5% for the two ports, respectively, and the measured gain is better than 16.7 dB in the operating bandwidth, which are suitable for synthetic aperture radar (SAR) application. © 2005 Wiley Periodicals, Inc.
