Abstract

In this article, a dual-band hybrid cylindrical dielectric resonator antenna (CDRA) is designed, analyzed, and experimentally validated. Miniaturization and dual-band frequency behavior are achieved by loading circular copper strips on top of the CDRA. Hence, the antenna resonates at 4.4 and 6.1 GHz covering −10 dB bandwidths of 600 MHz and 500 MHz, respectively. The proposed CDRA is excited using a rectangular slot for HEMY11 and HEMX11 modes. The proposed antenna demonstrates good gain (4.9 dBi at 4.4 GHz and 5.6 dBi at 6.1 GHz), high efficiency (>88% for all operating bands), and good FTBR (>10.08 dB in both principal planes for both operating bands). Moreover, the higher frequency band can be independently controlled by adjusting the parasitic strips width (d) and gap (g).
