Abstract
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 is made of a single-layer substrate and fed by a 50 Ω microstrip line. This antenna has attractive features including wide bandwidth, low profile, and high radiation efficiency. Also, it is easy to integrate the MPA with planar circuits. The whole structure is numerically evaluated using HFSS software package. Results show a simulated impedance bandwidth (S11(dB) ≤ -10 dB) of 9.6%, gain up to 7.5 dB and radiation efficiency is around 95%.
