摘要

介绍了一种基于基片集成波导的自三工加槽天线。所提出的天线包括在贴片上带有蚀刻加号槽的SIW腔以及三条独立且正交的50欧姆微带馈线。在这里，上部金属上的加号槽作为“T”形槽贡献，横向到各自的正交馈线，并产生8.5GHz, 9.7GHz和12GHz三个不同的谐振频率。通过正确选择天线的尺寸和参数，可以在任意两个输入端口之间获得最小23dB的固有隔离，这决定了天线的自三工特性。其包络相关系数最小值为0.02，前后比较高。实现了3.5、4.7、5.2dBi的稳定单向增益。

The Substrate Integrated Waveguide Based Self- Triplexing Cross Slot Antenna

The substrate integrated waveguide (SIW) based self-triplexing plus slot antenna is demonstrated in this paper. The proposed antenna comprises of SIW cavity with an etched plus-shaped slot on the patch along with three individual and orthogonal micro-strip feed lines of 50 ohms. Here the plus-shaped slot on the upper metallic is contributed as the "T"-shaped slot, transverse to the respective orthogonal feed lines, and produces the three distinct resonant frequencies of 8.5GHz, 9.7GHz & 12GHz. By properly selecting the proposed antenna dimensions and parameters, the intrinsic isolation of minimum 23dB is attained between any of the two input ports, which determine the self-triplexing property of the proposed antenna. It has the minimum value of the envelope correlation coefficient of 0.02 and a higher front to back ratio. It is also realized the stable and unidirectional gain of 3.5, 4.7 and 5.2dBi.
