Low profile circularly polarized SIW like cavity backed slot antennas
Two types of single fed low profile SIW like cavitybacked planar slot antennas for circularly polarization (CP) application are designed, fabricated and measured. Firstly, a spoon shaped slot structure cavity backed by a substrate integrated waveguide (SIW) cavity is proposed to realize the CP performance. Next, a half mode SIW (HMSIW) cavity backed semi circle slot antenna is proposed to further reduce the size of the antenna element. Finally, the measured and simulated results validate the proposed antennas.
