Abstract
This paper presents the design of a novel integrated mobile antenna for vehicles. The proposed antenna fabricated on a low cost easily available FR4 substrate, which effectively covers both dual band operation. The proposed mobile antenna is a modified G-type patch antenna that can operate in various frequency bands, GSM (880~960 MHz), AMPS (824~894MHz), DCS (1710~1880MHz), PCS (1850~1990MHz), UMTS (1920~2170). Experimental results indicate that the impedance bandwidth (VSWR 1:2.5) of the proposed mobile antenna agree that of the simulation results. It was validated that the configuration can meet the demands of Mobile frequency bands and effectively enhanced the impedance bandwidth to 36.46% for the lower band and 27.84% for the upper band. This paper also presents and discusses the 3D radiation patterns and gains according to the results of the experiment.
