A singly-fed differential dielectric resonator antenna for broadband applications
A differentially excited rectangular dielectric resonator antenna (RDRA) is proposed. The RDRA is excited with two equal magnitude signals with 18° out of phase. A well accepted hybrid coupler is designed on the same substrate and integrated with the RDRA. The RDRA able to achieve an optimum impedance bandwidth of 33.6% at center frequency of 2.76 GHz with this proposed feeding arrangement. The proposed feeding arrangement also provides a control over the impedance bandwidth. A detailed parametric variation is presented. The RDRA shows a stable radiation pattern with a steady gain of 6∼7.2dBi in the broadside direction over the frequency band of interest.
