| 摘 要： | 提出了一种基于铁电陶瓷的波导E面T型结,其工作频率为8 GHz.用丝网印刷的钛酸锶钡(Barium-Strontium-Titanate,BST)厚膜铁电陶瓷作为超材料,通过在波导中加入BST复合超材料来改变T型结的相位和频率.为了验证这种方法,设计并加工了频率在7.8～8.3 GHz的复合超材料T型结.仿真和测试结果表明,所设计T型结的插入损耗小于0.6 dB.同时,可以通过调节波导中BST铁电陶瓷的电压来实现波导T型结2个端口之间90°的相移.

| Abstract: | In this paper, a waveguide E-plane T-junction based on ferroelectric ceramics is proposed, which operates at 8 GHz. The metamaterial is achieved by a screen printed Barium-Strontium-Titanate (BST) thick-film ferroelectric ceramic, which can be loaded in waveguide for modifying phase and frequency of the T-junction. To validate this approach, a load Metamaterial T-junction prototype in the frequency range from 7.8 to 8.3 GHz is designed and fabricated. Experiment results show that the insert loss of the proposed T-junction is less than 0.6 dB. Meanwhile, the 90° phase shift between two ports of waveguide T-junction is achieved, which can be modified by adjusting voltage of BST ferroelectric ceramics in waveguide. |
