Abstract

The ground plane plays a crucial role in antenna performance. Variations in ground plane size can significantly alter the radiation pattern, affecting parameters such as gain, beamwidth, and axial ratio. This can pose challenges, for instance, in circularly polarized antenna arrays where individual elements may exhibit excellent circular polarization on a small ground plane but degrade when integrated into a larger array. In this paper, we use the dielectric resonator antenna (DRA) as an example to propose a method that renders the antenna insensitive to ground plane size variations. This approach is effective for both linearly polarized and circularly polarized antennas, with potential applications in array design and automotive antennas. © 2025 IEEE.
