摘要

本文提出了一种基于基片集成波导技术的宽带锥形缝隙天线阵列，用于毫米波应用。矩形波纹结构用于降低天线旁瓣电平，提高天线增益。在TSA元件上插入一对半圆形缺口，通过增加表面电流通路来扩大阻抗带宽。然后，设计并制作了一个四元TSA阵列。仿真结果与实测结果吻合较好。在回波损耗$< -10\ mathm {dB}$时，测量到的工作频带为33-46.8 GHz(相对带宽为34.5%)。此外，增益曲线在工作频段具有稳定的趋势，在46 GHz时最大增益为16 dBi。

A SIW-Based Wideband Tapered Slot Antenna (TSA) Array for MMW Applications

In this paper, a wideband tapered slot antenna (TSA) array using substrate integrated waveguide (SIW) technology is proposed for millimeter wave (MMW) applications. Rectangular corrugation structures are used to reduce side lobe level (SLL) and improve antenna gain. A pair of semicircular notches are inserted to TSA element to expand impedance bandwidth by adding surface current path. Then, a 4-element TSA array is designed and fabricated. Simulated and measured results obtain great agreement. The measured operating band is 33-46.8 GHz (relative bandwidth is 34.5 %) for return loss $< -10\mathrm{dB}$. Besides, gain curve has a stable trend at operating band and the maximum gain is 16 dBi at 46 GHz.
