摘要： 为解决微多普勒效应雷达的端射、小型化及宽频带问题，提出了一款紧凑型宽带端射阵列天线. 4个T型环缝天线单元中心对称放置于基板的背面，馈电网络位于基板的正面，从而形成耦合馈电，且馈电的幅度相同，馈电的相位在顺时针方向的分布为90°、270°、0°、180°. 经加工测试，其测试结果与仿真结果基本一致，且工作频带为5.72~6.71 GHz，绝对带宽为0.99 GHz，满足宽带特性的要求. 该天线采用易于集成的小型化平面设计，具有宽频带特性以及良好的端射性能，且加工成本较低，可以满足微多普勒效应雷达的实际应用要求.

Abstract: In order to solve the problems of endfire, miniaturization and broadband of the micro-Doppler effective radar, a compact broadband endfire array antenna is proposed.The four T-slotted antenna elements are symmetrically placed on the back of the substrate, and the feeding network is located on the front of the substrate, thus forming a coupling feed, which has same amplitude and the distribution of phase in the clockwise direction is 90°, 270°, 0°, 180°.After processing and measurement, the measured results are basically consistent with the simulated results, and the operating frequency band is 5.72~6.71 GHz, which has the absolute bandwidth of 0.99 GHz and satisfies the requirement of wideband characteristic.The antenna adopts an easy-to-integrate miniaturized planar design, and has broadband characteristic, good endfire performance, low processing cost, which can meet the practical application requirements of the micro-Doppler effective radar.

Key words: slot array antenna, compact plane, broadband, endfire, micro-Doppler effective radar
