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.
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.
