摘要

本文采用一种新型的哑铃形槽与薄基片集成波导(SIW)空腔背衬来设计双频槽天线。本设计具有单向辐射方向图、高增益、各谐振频率高(FTBR)，同时具有低轮廓平面结构。独特的槽形使不同频率下的电流分布复杂，导致腔内混合模式在高频处与常规模式不同时激励。传统模式和混合模式都有助于改进的槽在相应的谐振频率上辐射，从而形成紧凑的双频天线。该天线谐振频率分别为7.1 GHz和11.5 GHz，增益分别为6.7 dB和5.8 dB。在两个工作频率下，天线的FTBR都在10db以上。

Dual-Band Cavity-Backed Dumbbell-Shaped Slot Antenna

In this paper, a novel dumbbell-shaped slot alongwith thin substrate integrated waveguide (SIW) cavity backingis used to design dual-band slot antenna. The design in thispaper has unidirectional radiation pattern, high gain, high(FTBR) at each resonant frequency while having low profile, planar configuration. The unique slot shape creates complexcurrent distribution at different frequencies that results insimultaneous excitation of hybrid mode at higher frequencyalong with conventional mode in the cavity. Bothconventional mode and the hybrid mode helps themodified slot to radiate at the corresponding resonantfrequencies resulting in compact, dual-band antenna. Thisdesigned antenna resonates at 7.1 GHz and 11.5 GHz withgain of 6.7 dB and 5.8 dB respectively. The FTBR of theantenna are above 10 dB at both operating frequencies.
