Abstract	A compact dual-coupled shorting probe (DCSP)-loaded patch antenna for dual-band global positioning system (GPS) application is presented. Due to the use of shorting loaded technique, the overall size of the antenna is only λ_o/8 · 8 × λ_o/8 · 8 × λ_o/19 , and high-permittivity substrate is replaced by low-cost F4b substrate. The DCSP technique that this communication proposed enables this antenna to resonate at L1/L2 GPS bands. Simulated and measured voltage standing-wave ratio (VSWR) is below 1.5 over both the bands, and boresight RHCP gain is 4.49 and 4.12 dBic over a large ground plane with 41 and 57 MHz 3-dB gain bandwidth at the L2 and L1 band, respectively. Therefore, the proposed antenna is a good candidate for low-cost, dual-band, and compact patch antenna.
