为了避免并行馈电网络影响天线的全向性，采用了三扇区天线合成全向覆盖的方案，每个扇区天线是一个贴片天线阵列。
In order to achieve an ideal omni-directional pattern, the antenna consists of three parallel fed sub patch antenna arrays which are arranged in a triangular configuration.
平面单极天线以其结构尺寸小、工作频带宽、全向性能好、生产制作工艺简单等优点，广泛地应用于无线通信系统中。
The planar monopole antennas not only have these merits but also have the properties of wideband, low profile, and easily connecting to microstrip line feeding network.
