摘　　要：主要介绍针对课题"一种基于超宽带MIR运动传感器电路实现"而设计的接收和发射天线,在该课题中设计了四种天线即:平面螺旋天线、波导天线、指数天线和对称振子天线,并对它们进行了现场试验,其结果表明对称振子天线最适合MIR。现简要介绍对称振子天线基本情况,并重点介绍该天线的设计、制作与测试。The paper mainly introduces design and realization of sending and taking over antenna based on a kind of Ultra-wideband MIR movement sensor circuit. In the paper, four kind of antennas are designed, including planehelix antenna, wave-guide antenna, exponent antenna and symmetrical dipole antenna. Through the examinations on four kind of antennas, the result testifies that the symmetrical dipole antenna is fittest for MIR among them. Therefore, the paper briefly gives the elementary ease of symmetrical dipole antenna and mainly introduces the design, realization and test of it.
