Abstract

A compact monopolar microstrip patch antenna (MPA) with enhanced-bandwidth is proposed. In order to achieve the miniaturized patch, the zeroth-order mode of the MPA instead of its higher-order modes is employed at first by loading the shorting pin around the center of the patch. After that, a L-shaped microstrip line with a shorting pin is introduced at the periphery of the patch radiator to excite an additional non-radiative mode for bandwidth enhancement. In final, the proposed MPA is fabricated and measured. The results illustrate that the antenna generates an enhanced-bandwidth of about 4.1% ranging from 2.39 to 2.49 GHz, which is significantly larger than that of the traditional MPA around 1%. Meanwhile, the dimensions of the radiating patch are obviously decreased down due to the employment of zeroth-order mode, which are kept as small as about 0.17 λ0 × 0.22 λ0 × 0.026 λ0 (λ0 is the free-space wavelength).
