Abstract

A vehicular printed antenna for SDARS and GPS application is presented in this paper. The proposed antenna was printed on a FR4 substrate which is intended to be pasted onto the windshield of a car. The antenna has an overall size of 50 mm × 40 mm × 0.5 mm and consists of a semicircular slot and a rectangular-shaped ground plane, it can generate resonant mode at about 1.575 and 2.3385 GHz respectively. A 50-Ω coaxial mini-cable is employed to feed the antenna via a CPW structure. Both simulated and measured results show that the proposed antenna prototype achieves good impedance matching and omnidirectional radiation over the operating bandwidth at 1.5-1.62 GHz and 2.25-2.40 GHz, so that it is desirable for vehicular application as a SDARS and GPS dual-band antenna.
