In this study, an offset horn feed parabolic reflector antenna operating at 29.75 GHz Ka band
transmitter frequency, is designed, simulated and the directivity radiation pattern is plotted. Then an omega
metamaterial (MM) lens layer is designed to show double negative (DNG) characteristic in the same
frequency range and used inside the horn antenna and the far field radiation pattern was replotted. According
to the simulation results, when the MM lens is used, an increase of +3.7 dB in the directivity and a 4.3 °
decrease in the HPBW of the feed horn antenna, is observed.
