一种基于紧耦合结构的超宽带天线阵列设计
Design of an Ultra-wideband Antenna Array Based on the Structure of Tightly Coupled
摘要
Abstract
A ultra-wideband tightly coupled array is proposed.The antenna consists of two layers of printed dipole unit.The disconnected dipole located in the top is parasitic layer.The unit that is increased the coupling structure at E-plane is radiation lay.Feed network is composed of Marchaned balun and broadband Wilkinson power dividers.The simulation results show that the antenna achieves 0.9 GHz ～ 4.8 GHz bandwidth for VSWR ＜ 2,and have E-plane 6 0 °,H-plane 4 5 ° scanning range in 1 GHz ～ 4 GHz.This antenna has characteristic of broad bandwidth,large scan angle,and lightweight,which can be applied to small ultra-wideband phased antenna array system.关键词
