摘要/Abstract

摘要： 为了对工作于Ku频段(12.25’12.75 GHz)的低剖面平板天线进行研究,设计一种新型高增益角锥喇叭天线作为其天线单元。为实现天线的双线极化,考虑天线的辐射口面具有结构对称性,将天线的馈电波导设计成方形波导。采用三维电磁仿真软件HFSS (High Frequency Structure Simulator)对角锥喇叭天线进行设计与仿真,并利用软件的优化功能对天线增益进行优化。仿真结果表明：天线在Ku频段内,增益不低于15.4 dB,反射系数优于-21 dB,电压驻波比VSWR(Voltage Standing Wave Ratio)不大于1.19,且方向性在中心处达到最强。所设计的角锥喇叭天线增益高,尺寸小,易实现低剖面平板天线的设计要求。

Abstract: In order to study the low-profile panel antenna that works in Ku band (12.25’12.75GHz), a high-gain Pyramidal horn antenna is designed as the unit of low-profile panel antenna. To meet dual polarization, it was taken into account that the radiation aperture of antenna unit has symmetric structure. Thus the feed waveguide is designed into a square waveguide. The proposed antenna is designed, simulated and optimized for antenna gain with HFSS (High Frequency Structure Simulator) software. Simulated results show that: in the Ku band, the reflection coefficient is less than -21dB; and the VSWR (voltage standing wave ratio) is less than 1.19; and the gain is more than 15.4dB; and then the directivity achieves the strongest at the center. Therefore, the designed antenna has high gain and small size, which can meet the design requirements of low-profile panel antenna.

Key words: horn antenna, HFSS, high gain, panel antenna
