摘要

设计了一种工作在Ka波段的高增益宽带锥形缝隙天线(TSA)。TSA印在基板的两面。在微带馈线和TSA之间采用SIW变压器，以最大限度地减少馈线的损耗，从而形成天线阵列。反射系数小于-10dB的模拟带宽在25GHz ~ 51GHz范围内为26GHz。前后比为15dB，半功率波束宽度为60°。这个原型被制作和测量来验证这个设计。该天线元件易于扩展成阵列，应用于毫米波功率传输和成像。

A millimeter tapered slot antenna fed by SIW with broadband and high gain

A tapered slot antenna (TSA) operates at Ka band with high gain and broadband is designed in this paper. The TSA is printed on two side of the substrate. A SIW transformer between the microstrip feedline and the TSA is applied to minimize the feedline losses for forming antenna arrays. The simulated bandwidth of the reflection coefficient less than -10dB is 26GHz from 25GHz to 51GHz. The front-back ratio is 15dB and the half power beam width is 60°. This prototype is fabricated and measured to verify this design. It is easy for this antenna element to be expended to array and applied in millimeter wave power transmission and imaging.
