Abstract

A design of substrate integrated waveguide (SIW) based self-diplexing dumbbell-shaped slot antenna is presented in this paper. The proposed antenna comprises of two micro-strip feed lines of impedance 50Ω and two parallel dumbbell-shaped slots. These transverse parallel slots are of different lengths, etched on the patch (top surface) of the SIW cavity; produce two resonant frequencies at 8.12GHz & 10.15GHz. The proposed self-diplexing antenna is based on the function of operating mode and perturbation of the higher order modes methodology. The better intrinsic isolation of 26.5dB is obtained between two input ports, which define the unique property of the self-diplexing antenna and reduce the space and size of overall wireless transceiver modules. The proposed antenna produces the unidirectional radiation pattern, high front to back ratio (>17 dB) and gain of 4.7dBi & 5.2dBi at two resonant frequencies of 8.12GHz & 10.15GHz for the X- Band application as satellite and wireless communication systems.

基于SIW的X波段自双工哑铃槽天线

提出了一种基于基片集成波导(SIW)的自双工哑铃型缝隙天线的设计方法。该天线由阻抗为50Ω的两条微带馈线和两个平行的哑铃形槽组成。这些不同长度的横向平行槽蚀刻在SIW腔体的贴片(顶表面)上;产生8.12GHz和10.15GHz两个谐振频率。本文提出的自双工天线是基于工作模式函数和高阶模态摄动的方法。在两个输入端口之间获得了26.5dB的良好本征隔离，定义了自双工天线的独特特性，减小了整个无线收发模块的空间和尺寸。该天线在8.12GHz和10.15GHz两个谐振频率下产生单向辐射方向图、高前后比(> 17db)和4.7dBi和5.2dBi增益，适用于卫星和无线通信系统的X波段应用。
