Wideband Endfire Dielectric Resonator Antenna Employing Fundamental and Higher Order Magnetoelectric Resonances

A broadband endfire dielectric resonator antenna (DRA) is proposed based on three synthesized magnetoelectric resonances. These resonant modes have distinct features compared with the classical ones in regular DRAs. Field analysis and Cartesian multipole extraction are conducted to characterize the synthesized modes and guide the design. By adjusting the electric and magnetic modal multipoles, the bandwidth and front-to-back ratio (FBR) are enhanced. Moreover, the contribution from the multifunction feed and ground plane is also investigated. The DRA shows an overlapped impedance and FBR bandwidth of 38%.
