针对现有的微波探测模块工作天线在实际应用中的适应能力有限,较差的探测稳定性等缺陷,本文提出了一种波束宽度可调的微带天线。天线的尺寸为6.8 mm×6.7 mm×1.07 mm,工作频率为10.525 GHz,天线的E面和H面半功率波束宽度为83.58°和78.66°。该天线直接放置在长形介质下方,通过调整介质与辐射贴片的距离,微带天线E面和H面半功率波束宽度分别扩展为192.5°和200.5°有明显扩展效果。可调微带天线并没有加载任何的开关和二极管,所以在最大程度上减小了系统的插入损耗,同时也没有额外的外置直流偏置电路,降低了系统的功耗。

Aiming at the defects of the existing microwave detection module working antenna, such as limited adaptability and poor detection stability in practical application, a microstrip antenna with adjustable beam width is proposed in this paper. The size of the antenna is 6.8 mm × 6.7 mm × 1.07 mm, the operating frequency is 10.525 GHz, and the half power beam widths of E plane and H plane of the antenna are 83.58° and 78.66°. The antenna is directly placed under the long medium. By adjusting the distance between the medium and the radiation pat...
