Abstract
This article presents a compact dual-band hybrid dielectric resonator antenna for wireless communication systems. The proposed design uses a square dielectric resonator loaded with magnetic-LC resonator (complementary of electric-LC resonator) to achieve miniaturization and dual-band operation. Based on the parametric analysis, it is reveled that the two operational bands could be designed independently. The proposed antenna operates at 3.6 and 5.25 GHz with impedance bandwidths of 3.9% (3.53–3.67 GHz) and 3.24% (5.17–5.34 GHz), respectively. The antenna radiates with similar radiation pattern at both the operating frequencies with the cross polarized fields better than 20 dB. The peak gain of the antenna is 6.27 and 6.35 dBi at lower and upper operating frequency, respectively. The proposed antenna is suitable for worldwide interoperability for microwave access and wireless local area network band applications.
