Abstract

A novel broadband aperture-coupled microstrip patch antenna is proposed in this paper. The proposed antenna is fed by a coupling aperture, which is offset from the patch center. This generates a fictitious open circuit along the resonating edges of the patch, and therefore, an additional resonant frequency is produced, and a wide impedance bandwidth can be obtained. Comparing to the conventional aperture-coupled patch antenna, the impedance bandwidth (|S₁₁| <; -10 dB) is enhanced from 8.5% (11.22-12.21 GHz) to 15.7% (11.58-13.55 GHz). Experimental results, which agree well with the simulated ones, verify the performance of our proposed antenna.
