高性能动态聚焦漏波天线阵列
A High-Performance Dynamically Focused Leaky-Wave Antenna Array
摘要
Abstract
A high-performance dynamically focused leaky-wave antenna array(DFLWAA)is proposed in this paper.First,the leaky-wave antenna unit based on composite right/left-handed transmission line is presented.The beam direction of the array formed by such units can change with the operating frequency.Then,a differential feeding network is proposed.When properly adjusted,the feeding network outputs signals of nearly equal amplitude and opposite phase.The proposed dynamic focusing scheme is based on a configuration consists of two 1×4 leaky-wave antenna arrays and a differential feeding network.Simulation and experimental results show that the proposed design achieves a large dynamic focal range of 160 mm with an aperture length of only 225 mm.Finally,the frequency-scanning focusing performance of the proposed design from 4.8 GHz to 5.9 GHz is reported.This design achieves large-range dynamic focusing while avoiding complex feeding systems,with a simple structure.All these features make the proposed dynamically focused leaky-wave antenna array a high-performance solution for focus-tunable antennas.关键词
