摘要

本文提出并研究了一种用于K波段(18ghz - 27ghz)卫星通信的高增益光透明微带贴片天线。为了保证天线的光学透明性，微带贴片天线的各层都选用了光学透明材料。辐射贴片和接地面选用氧化铟锡(ITO)薄膜，衬底由耐热玻璃(有损)制成(Ɛr = 4.82, tanδ = 0.0054)。该透明天线工作在24.8 GHz的中心频率范围为17.625 GHz至30.523 GHz，覆盖卫星通信的整个K波段。贴片天线的透明特性有助于减小太阳天线的遮蔽效应，保证卫星表面积的最大利用。该天线的IEEE增益为12.36 dB，指向性为13.38 dBi，效率为92.38%。它还具有非常宽的带宽(12.898 GHz)，高前后比(16.699 dB)和非常好的驻波比(1.0566)在中心工作频率。

An ITO Based High Gain Optically Transparent Wide Band Microstrip Antenna for K Band Satellite Communication

A high gain optically transparent microstrip patch antenna for K band (18 GHz–27 GHz) satellite communication has been proposed and investigated in this paper. In order to make sure the property of optical transparency of the antenna, optically transparent materials have been chosen for all the layers of the microstrip patch antenna. Indium Tin Oxide (ITO) film is opted for the radiating patch and ground plane where the substrate is made of pyrex glass (lossy) (Ɛr = 4.82 and tanδ = 0.0054). The proposed transparent antenna operates at center frequency of 24.8 GHz ranging from 17.625 GHz to 30.523 GHz that covers the entire K band of satellite communication. The transparency property of the patch antenna is useful to minimize the shadowing effect of the solar antenna as well as helpful to guarantee the maximum uses of satellite surface area. The proposed antenna has high IEEE gain of 12.36 dB and directivity of 13.38 dBi including efficiency of 92.38%. It also possesses very wide bandwidth (12.898 GHz), high front to back ratio (16.699 dB) and very good VSWR (1.0566) at center operating frequency.
