摘要
This article proposes a dielectric resonator in the form of a quarter of a cylinder to perform as a circularly polarized antenna using a very simple feed design on which a single probe excites two resonant modes in phase quadrature and spatial orthogonality. This study examines some electromagnetic aspects of this antenna and it also presents and discusses the results achieved from computational simulation and experimental measurements. It was verified a good agreement between simulated and experimental results showing a 3-dB axial ratio bandwidth over 3% at 2.25 GHz. (C) 2015 Wiley Periodicals, Inc.
