摘要

为了支持覆盖日本地区(波束覆盖高程，El = 38°~ 58°)的卫星能量通信移动互联网，提出了一种简单的左旋圆极化(LHCP)近馈带孔的等边三角形阵列天线。研制了用于地面接收机的单波段LHCP三角贴片阵列天线。在东京地区，天线的目标最小增益在中心仰角(El = 48°)设置为5dbic，用于使用大约数百kbps的数据互联网传输。天线由三个等边三角形的贴片组成，上面有一个孔，用于在2.50 GHz频段工作的接收单元。采用矩量法(MoM)对天线进行了仿真。仿真结果表明，仿真天线在圆锥切割方向的频率特性和3db轴比覆盖率满足目标要求。

The Array Microstrip Antenna for Mobile-Internet of Satellite Energy Communication

A simple Left-Handed Circularly Polarized (LHCP) proximity-fed equilateral-triangular array antenna with hole is proposed in order to support the mobile-internet of satellite energy communication covering the area of Japan (beam coverage elevation, El = 38° to 58°). In this paper, single-band LHCP triangular-patch array antenna is developed for receiver on ground applications. The targeted minimum gain of the antenna is set to 5 dBic at the central elevation angle (El = 48°), in Tokyo area, for applications using data-internet transfer of around hundreds kbps. The antenna consists of three equilateral-triangular patches with a hole for reception units operating at 2.50 GHz frequency bands. The antenna is simulated using the Method of Moments (MoM) analysis. The simulation results show that the frequency characteristics and the 3-dB axial ratio coverage in the conical-cut direction of the simulated antenna satisfy the target.
