Abstract :
A dual band vehicular telephone antenna with a low profile and wide bandwidth is presented. Operating at the 900 MHz and 1800 MHz telephony bands, with a VSWR of better than 1.7, it is a hybrid construction combining a monopole with a top loading patch shorted to the ground-plane. Extra pins provide the upper frequency band resonance. The antenna has monopole radiation characteristics and can be hidden under a plastic panel or mounted on the vehicle roof
