Design of Single-Fed Dual-Polarized Planar Antenna for Dual-Band Automotive Applications

This proposed work revealed a novel structure of asymmetric v-shaped slots patch antenna fed with single coax-fed for generating dual bands, i.e. GPS L2 (1.227 GHz) and with SDARS (2.320–2.345 GHz) bands with right hand circular polarization and left hand circular polarization, respectively. Dual-band process and dual-polarization radiation are achieved by cut of four asymmetric v-shaped slots on the radiator. The entire volume of the proposed structure is only 61.67 \(\times \) 61.67 \(\times \) 1.6 mm\(^{3}\), interpreting it gorgeous for the automotive systems market. A prototype of the proposed model is printed, and its simulated performance was validated with measurement. Measured data illustrated that the designed antenna radiates RHCP and LHCP wave independently.
