摘要

本文介绍了用于24ghz防撞雷达的同相贴片天线的设计和测量结果。该天线由24个连续连接的贴片组成的两个线性阵列组成。其目的是设计一种在ISM 24.05-24.25 GHz范围内方位瓣数低于-20 dB的天线，在此范围内防碰撞雷达可以工作。在24.1 GHz频率下，实现的天线增益为21.75 dB，效率为60%。三分贝带宽在方位角为3.6/声压角/，在仰角为46/声压角/。在24.05-24.25 GHz范围内，增益高于21.15 dB，反射系数低于-14 dB。

High efficiency patch antenna for 24 GHz anticollision radar

This paper presents design and measured results in synphase patch antenna for anticollision radar at 24 GHz. The antenna consists of two linear arrays of 24 serially connected patches. The aim was to design an antenna that in azimuth has lobes below -20 dB in ISM range of 24.05-24.25 GHz, at which the anticollision radar operates. The realized antenna has gain of 21.75 dB and efficiency of 60% at the frequency of 24.1 GHz. Three-decibel bandwidth in azimuth is 3.6/spl deg/ and in elevation is 46/spl deg/. In the range of 24.05-24.25 GHz, gain is higher than 21.15 dB and the reflection coefficient is below -14 dB.
