无线数据采集系统915MHz天线的设计∗
Design of an Antenna Operating at 915 MHz Used in Wireless Data Collection Systems
摘要
Abstract
A printed dipole antenna operating at 915 MHz is proposed. The antenna is fed by a microstrip to copla-nar stripline Balun to achieve broadband operation and balanced feed in the band. The impedance bandwidth deter-mined from a 10 dB return loss is found to be about 22%,with the bandwidth 830 MHz to 1 030 MHz. The antenna has excellent performance of S11<-50 dB at 915 MHz. The antenna has characteristics of simple structure,and is easy to be integrated. It can be used in wireless data collection systems.关键词
