Abstract
A stacked hollow dielectric resonator antenna (SHDRA) is presented in this article. It consists of two dielectric layers with different permittivity materials etched as a dielectric resonator, stacked, or segmented to each other. This antenna is placing dielectric layers with high permittivity material (ε = 9.8) and low permittivity material (ε = 4.4), fed through a slot (tilted 45°). This paper presents a wideband SHDRA designed with a low profile and high gain. The antenna can achieve gain range 7–8.4 dB, frequency band range 3.7–5.8 GHz, and impedance bandwidth 52.76% at the center frequency of 4.1 GHz.
