Abstract :
A practical design is described for a multibeam antenna for electronic support measures systems. The antenna is formed by an R-KR lens-fed semicircular array. The number of radiating elements of the array is 18, and they are linear tapered slot antennas (LTSA). Both the lens and the array have been built with the same dielectric substrate and in the same plane. The antenna operates over a frequency range of 2:1.<>
