balanced dipole meaning in Chinese

对称振子

Rfid antennas we research operate at 915mhz , which belong to vhf , therefore microstrip patch antenna is adopted as base station antenna and various balanced dipole antennas are employed as tag antennas . then , a brief introduction is given on the radiating principles of the microstrip antenna
由于本课题所研究的rfid天线主要工作于915mhz ,属于甚高频波段,因而基站天线主要采用微带贴片型,标签天线主要采用各种对称振子型天线。
Antennas are feed by 50ohm coaxial cable and feed networks are unnecessary . and then , tag antennas are analyzed and designed , which include plate balanced dipole antenna , triangle balanced dipole antenna and inductively coupled feed meander - line antenna . theory analysis and simulations are given and optimal results are achieved
然后,对标签天线进行了分析与设计,分别对片状对称振子天线、三角形对称振子天线、感应耦合馈电折叠线天线等天线形式进行了研究,给出理论分析和仿真计算,得到满足设计要求的各种形式的标签天线。
