Abstract :
A large rectangular horn antenna with a center frequency of 2.0 GHz, corrugated on the E-plane walls, made out of aluminium sheet, has been designed, constructed, and tested. A technique has been developed to solder thin aluminium strips onto the back plane to form the corrugations. The radiation beam pattern shows half-power beamwidths of 12° and 14° in the H- and E-planes, respectively, and sidelobe response below -40 dB at angles greater than 50° from the horn axis. The measured return loss is greater than 20 dB (VSWR<1.22) between 1.7 and 2.3 GHz; insertion loss is less than 0.15 dB
