本文介绍了一种工作在5.3 GHz的微带阵列天线的设计和结构，用作雪崩测量中的雪崩传感器。该天线的优点是可以在90%的带宽下获得15.6dB的高增益。这是通过将馈电网络与主贴片分离来实现的;并通过将馈电层安装在贴片层的背面来增加天线高度，共享同一接地平面。为了确保功率从主输入端口平滑传输，馈电设计为新型蜘蛛状锥形馈电网络，同时确保整体天线功能不受影响。
This paper presents the design and construction of a microstrip array antenna operating at 5.3 GHz, to be used as an avalanche sensor in avalanche measurement. The advantage of the antenna is it can achieve a high gain of 15.6 dB with bandwidth of 90%. This was achieved by separating the feed network from the main patches; and increasing the antenna height by installing the feed layer at the back of the patch layer, sharing the same ground plane. In order to ensure the power is transferred smoothly from the main input port, the feed is design in novel spider like tapered feed network while ensuring the overall antenna function is not compromised.
