Abstract
A dual band and dual polarization slot patch antenna for Global Positioning System (GPS) and wireless LAN network with the corresponding polarizations is proposed. An L-shaped slot and a small stub are utilized to excite the desirable right-hand circular polarization (RHCP) for GPS. Meanwhile the linearly polarized electromagnetic wave for Wi-Fi communications at 2.4 GHz is contributed by an arc-shaped slot embedded circular patch. The multi-layered geometry and the capacitive feeding disk placed between the substrate layers enhance the operating bandwidths of the antenna. The achievable percentage bandwidths at the low and high bands are 6.4% and 7% respectively. The measured 3dB axial ratio (AR) bandwidth is 34 MHz, which covers the GPS L1 band.
