Abstract

In order to achieve high gain in the azimuth to cover 360-degree range., a distributed multi-beam antenna based on switch transformation technique is proposed. Each antenna can cover 45-degree range in the direction of azimuth (eight antennas cover 360 degree) and 30 degree in the direction of elevation., respectively. The light weight and low cost Aperture Coupled Microstrip Antenna (ACMSA) is designed to broaden the bandwidth of the traditional microstrip antenna. The CST MWS is used to simulate and optimize the antenna element. Based on the designed antenna element., an array antenna is introduced. The array antenna prototype is fabricated using PCB processing technique and the measurement for the array is conducted., the measured results show a good agreement with the simulation where the gain of the antenna is about 10.7dBi and the S11 parameter of the antenna is less than −10dB in the frequency range, respectively. 8 array antennas are assembled upon aluminum sustain structure to cover 360 degrees in the direction of azimuth and each array antenna can be selected by the switch to realize communication.

用于微波通信的x波段分布式多波束天线

以实现高增益在方位角上覆盖360度范围。提出了一种基于开关变换技术的分布式多波束天线。每个天线在方位角方向可覆盖45度范围(8个天线覆盖360度)，在仰角方向可覆盖30度。,分别。孔径耦合微带天线(ACMSA)是为了提高传统微带天线的带宽而设计的。利用CST MWS对天线单元进行仿真和优化。基于所设计的天线元件。，介绍了一种阵列天线。采用PCB加工技术制作了阵列天线样机，并对阵列进行了测量。在该频率范围内，天线的增益约为10.7dBi，天线的S11参数小于- 10dB，测量结果与仿真结果吻合良好。8个阵列天线安装在铝制支撑结构上，方位方向360度覆盖，可通过开关选择各阵列天线实现通信。
