Abstract
A multibeam antenna prototype for an ESM system is presented. The antenna is formed by a semicircular array of Vivaldi radiating elements, fed by an RKR microstrip lens. Both the lens and the array are printed on the same dielectric substrate. The antenna operates over one octave frequency band. Diagrams measured for two input terminals are shown. Sidelobe levels are maintained under -15 dB except for the most lateral beam diagram. Input reflection losses at any port are over 10 dB.<>
