摘要

研究了一种宽带差分馈电矩形介质谐振器天线。提出的DRA基于宽带平衡-平衡微带-插槽功率分配器（MSPD）。平衡式MSPD采用槽线的多模共振设计，实现了10db差分阻抗带宽为87% （1.84-4.45 GHz）。矩形DRA可以被激发在宽带TE111模式下工作。该DRA具有约42.6% （2.48-3.74 GHz）的10db差分阻抗带宽和峰值增益为5.2 dBi的宽侧辐射方向图。所提出的差动馈电机制可以很好地与宽带差分电路相匹配。

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

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.
