A novel method for bandwidth enhancement of Substrate Integrated Waveguide (SIW) cavity-backed slot antenna is introduced for a single element and an array configuration. Using a corner cut in the SIW square cavity, resonant frequency of two degenerate TE 210 and TE120 modes of a square cavity are separated and impedance bandwidth is improved. The simulated and measured results of the antennas show at least 140% and 220% wider bandwidth compared to the bandwidth of a conventional single cavity antenna for single and two element array antennas, respectively. The presented antennas provide a few advantages including low profile, light weight, easy fabrication with low cost and convenient integration with planar circuits.
