一种用于移动通信系统的宽带定向天线设计
Design of a wideband beam antenna used in mobile communication system
摘要
Abstract
Due to narrow bandwidth and poor radiation directivity of the symmetrical dipole antenna,the parasitic patch loading technology is used,the operating bandwidth is expanded and the antenna gain is improved by loading low-frequency and high-frequency parasitic dipole.The measure results show that the antenna is covering two frequency bands:800～1040 MHz and I 540～2 500 MHz,the relative bandwidth is 26.1％ and 47.5％,and the peak gain in two bands is 6.44 dB and 9.64 dB.The designed antenna is covering AMPS,GSM,DCS,PCS,UMTS and WLAN,and its radiated direction is stable.The application prospect is expansive.关键词
