In this paper, a novel design of wideband compact patch antenna is proposed for the handheld application of global navigation satellite system (GNSS). In order to meet the size requirement of the handheld application, the shorting load is employed as the miniaturization technique and the overall size of the proposed antenna is only 70 mm (length) × 70 mm (width) × 25 mm (height). Due to the narrow bandwidth of the shorting loaded patch antenna, shorting probe with enlarged width, as well as the air substrate, is adopted to enhance the bandwidth of the proposed antenna and make it fulfil the GNSS bandwidth requirement. Simulation and measured results show that the proposed antenna has a bandwidth of 41.5% for VSWR < 1.5 from 1.05 to 1.6 GHz and 35.7% 3-dB axial ratio bandwidth from 1.15 to 1.65 GHz.
