Roof-Glass Integrated Antenna for Vehicular GNSS Applications
(2024) 18th European Conference on Antennas and Propagation, EuCAP 2024- Abstract
- In this paper, a wideband circularly polarized antenna is designed for integration into the glass roof of a modern car for GNSS positioning applications. Characteristic mode analysis is used to obtain more physical insight into the problem and hence satisfy the polarization and bandwidth requirements. The antenna has a low profile and uses a single coplanar waveguide feed to cover all GNSS bands. The measured 10 dB impedance bandwidth of the prototype is 52% and the 3 dB axial-ratio (AR) bandwidth is 39%. Full-car simulation results are presented for different antenna positions on the roof. It is shown that the middle and rear-right positions are preferred in terms of the AR performance.
