Abstract
A primary radar antenna, designed as a pillbox antenna, has an IFF antenna integrated therewith. Excellent properties with regard to compactness, radiation and frequency dependency are achieved through the combination of a pillbox antenna with a multiple IFF antenna composed of a plurality of radiator elements, which is applied on the upper side of the pillbox antenna for radiation of the IFF signals. The antenna is particularly suitable as a combined primary radar/IFF antenna for smaller vehicles.
