本文提出了一种全向天线阵。该阵列的天线单元由十个辐射贴片和相关的微带馈电网络组成。在天线的顶部和背部贴片之间引入一些间隙，以改善匹配，易于馈电和提高带宽。微波实验和数值模拟进行演示天线的功能。在驻波小于等于1.5时，天线带宽为14%（1 ~ 1.15 GHz），增益约为6dBi。研究结果对设计和评估具有良好阻抗匹配的全向平面天线阵具有重要的参考价值，对机载和导航应用具有重要意义。
An omnidirectional antenna array is proposed in this paper. The antenna unit of the array is composed of ten radiation patches and the associated microstrip feeding network. Some gaps between top and back patches are introduced in the antenna to improve matching, ease of feeding and enhance the bandwidth. Microwave experiments and numerical simulations are performed to demonstrate antenna functionalities. The fabricated antenna exhibits a bandwidth of 14% (1–1.15 GHz) for VSWR ≤ 1.5, with a gain around 6dBi. The results are valuable for the design and evaluation of omnidirectional planar antenna arrays with good impedance matching, which are important for airborne and navigation applications.
