Abstract :
This paper presents a circularly polarized crossed dipole antenna mounted on a 1-m circular ground plane for reception of satellite digital radio signals within the S-band in automotive applications. The main radiator consists of a pair of dipole antennas connected to separate nonresonant lines of unequal length to achieve the current are in phase quadrature and right hand circular polarization (RHCP). A two-ray model utilized to provide a fast estimation method to analyze the radiation pattern characteristic of the proposed antenna. The simulation results show the ground plane influences on the radiation pattern of the antenna at specific elevation angles for satellite broadcasting system.
