A bidirectional dielectric resonator (DR) antenna array using back-to-back quasi-Yagi antenna configuration is proposed and implemented for the first time. The DR operating at higher-order TE3δ1 mode is used as a magnetic dipole, applying for the driver of quasi-Yagi antenna. Due to the high-order mode employment, the antenna gain can be enhanced. By partially loading the metallic strip on the side wall of the DR, the gain can be further enhanced. In addition, a simple dual Marchand balun is constructed for feeding the two quasi-Yagi antennas directly for bidirectional radiation. To verify the design concept, a prototype operating at the X-band is fabricated and measured. Good agreement between the simulated and measured results can be observed.

TE3δ1模式下使用带载介质谐振器的X波段增益增强双向天线阵列

首次提出并实现了一种使用背靠背准八木天线配置的双向介质谐振器（DR）天线阵列。以高阶 TE 运行的 DR3δ1模式用作磁偶极子，适用于准八木天线的驱动器。由于采用了高阶模，可以提高天线增益。通过在DR的侧壁上部分加载金属条，可以进一步提高增益。此外，还构建了一个简单的双 Marchand 巴伦，用于直接为两个准八木天线馈电以实现双向辐射。为了验证设计概念，制作并测量了一个在 X 波段工作的原型。可以观察到模拟结果和测量结果之间的良好一致性。
