A novel design of feeding Microstrip Patch Antennas (MPAs) using Half Mode Substrate Integrated Waveguide (HMSIW) technique is proposed. The design is based on the half-mode circular SIW cavity operating at TM010 mode. The proposed antenna structure...

Two low profile hybrid antennas are presented. One of the structures provides linearly polarized (LP) wave and the other one produces circularly polarized (CP) radiated field. Half-mode Substrate Integrated Waveguide (HMSIW) ...
