A compact dual feed integrated triple-band vehicle antenna for GPS and RKES/PCS operation is proposed. The GPS (1575.42 1.023 MHz) antenna element is a corner truncated microstrip patch providing circularly polarized broadside radiation pattern. The RKES/PCS (447.7375 MHz/1750-1870 MHz) antenna consists of two printed monopoles fed by coplanar waveguide (CPW) transmission line. To reduce the height of RKES antenna, modified inverted-L monopole structure is utilized. The proposed antenna satisfies all the bandwidth and gain requirements for GPS and RKES/PCS services. Good radiation characteristics for vehicle application have also been obtained.
