“…Due to the rapid proliferation of wireless commination technology, there is an urgent need of highperformance and low-profile antennas providing compatibility with planar circuits. Micro-strip antenna possesses a bidirectional pattern with light weight, easy fabrication, and easy integration [1][2][3]. Traditional cavity-backed antennas render low back radiation, low loss, and high gain.…”

In this paper, a bandwidth improvement technique in SIW slotted antennas is presented. Distinct from conventional SIW antennas with multiple cavity modes, a single cavity mode (TE 210 ) is utilized to improve the bandwidth. When a rectangle slot is loaded at bottom surface of the cavity, the TE 210 cavity mode is perturbed. As a result, two independent modes (odd TE 210 , even TE 210 ) are introduced and merged in close proximity. Finally, the antenna is fabricated and tested. The measured results render an impedance bandwidth of 12.8% and a maximum gain of 7.1 dBi. The cross-polar level of maximum −29 dB and −34 dB is at 9.73 GHz and 10.63 GHz, respectively. The proposed design holds many features such as easy fabrication and light weight. Besides, the proposed design is single-layered that makes it extremely convenient to integrate with other planar configurations.
