Characterization and Performance Measurement of Low RCS Wideband Circularly Polarized MIMO Antenna for Microwave Sensing Applications

This article presents a low radar cross section (RCS), compact wideband, circularly polarized, multiple-input-multiple-output (MIMO) antenna for microwave sensing and measurement applications in S-and C-bands. The proposed antenna consists of a wide slot and an I-shaped protruding stub in the ground plane of the antenna. A U-shaped strip is incorporated between two microstrip feed lines to achieve...
