摘要：This paper presents design and measured results in synphase patch antenna for anticollision radar at 24GHz. The antenna consists of two linear arrays of 24 series-fed patches. The aim was to design an antenna that in azimuth has lobes below -20dB in ISM range of 24.05-24.25GHz, at which the anticollision radar operates. The realized antenna has gain of 21.75dB and efficiency of 60% at the frequency of 24.1GHz. Three-decibel bandwidth in azimuth is 3.60 and in elevation is 460. In the range of 24.05-24.25GHz, gain is higher than 21.15dB and the reflection coefficient is below ¨C14dB
