C波段高增益平板微带天线设计

摘要
微带天线是一种体积小,重量轻,剖面薄,制作方便,易于与载体共形的天线。其在无线通信、雷达、遥感、电子对抗等众多领域获得了广泛应用。然而微带天线的频带窄,增益低。为了弥补这些不足,通常需要对微带天线的结构做出调整,然后运用合理的方式把它们组成天线阵列。
本文的主要工作是,为了某些通信设备的需要,设计4.5GHz-5.0GHz的天线,要求在该频段天线的驻波比VSWR≤2,平均增益28-29.5dB,这里我们用微带U_Slot矩形贴片作为单元,引入π结构采用近邻耦合方式进行馈电,组成天线阵列来实现。
本文以微带天线的基本电磁场理论为依据,通过Ansoft公司的HFSS(高频结构仿真软件)建模仿真,对微带天线的结构进行了深入的研究,在此基础上设计并制造。通过实验室所提供的天线测量设备对所设计出来的天线进行测试,发现用软件仿真的结果和实际测量的结果有较好的一致性。
Micro-strip antenna is an antenna which has little valume, light in weight, thin profile, easily conformaity with carrier. It is connected with broad application in many areas, such as correspondence, radar, remote sensing, and electronic countermeasure. However, the band of micro-strip is rather narrow, the gain is low. In order to solve these shortages, we usually adjust the structure of micro-strip antenna, and adopt comfortable manner to compose antenna array with them.
Objective of the study is design an atenna, which works form 4.5GHz to 5.0GHz, for some correspondence equipments, and demanding the VSWR≤2 in the frequence bandwidth, the average gain is 28-29.5dB. The single antenna is micro-strip U_Slot rectangular patch, and the feed manner is proximity-coupled withπstructure. We will adopt antenna arrays to complish these demandings.
The study gives an in-depth analyzing in micro-strip antenna structure on the basis of basic electromagnetic field theory of micro-strip antenna, then models and simulates by HFSS of Ansoft Company, finally designs and products it. We test the antenna with antenna measure equipment which is offered by lab, amd have discovered that there is conherence between the result of software simulation and the result of actual messurement.
