Wideband Differential Dielectric Resonator Antenna Using Balanced Microstrip‐To‐Slotline Power Divider

Year: 2025

Type: article

Abstract: ABSTRACT A wideband differentially fed rectangular dielectric resonator antenna (DRA) is investigated in this paper. The proposed DRA is based on a wideband balanced‐to‐balanced microstrip‐to‐slotline power divider (MSPD). The balanced MSPD is designed using the multi‐mode resonance of a slotline which realizes a broad 10‐dB differential impedance bandwidth of 87% (1.84–4.45 GHz). The rectangular DRA can be excited to operate in a wideband TE111 mode. The DRA has a 10‐dB differential impedance bandwidth of about 42.6% (2.48–3.74 GHz) and a broadside radiation pattern with a peak gain of 5.2 dBi. The proposed differential‐to‐differential feeding mechanism to excite DRA can perfectly match with wideband differential circuits.
