Abstract :
The circular polarization (CP) characteristics of an electromagnetically coupled patch (EMCP) antenna of both coplanar and stacked geometries have been studied experimentally. Compared to the single CP patch antenna, the EMCP antennas were found to have better axial ratio bandwidth and directivity.<>
