Abstract :
The present work presents gain enhancement using a Diffraction Optical Element (DOE) lens. The design of the lens, made of Rexolite, is discussed. It is placed in front of a radiating antenna and modeled in HFSS and CST. Beam focusing has been illustrated It is shown that the size of the lens is directly proportional to gain increase which can be as high 25 dB enhancement. Nevertheless a more realistic size still results in a 10dB increase at 40 GHz The lens can be easily constructed and experimental validation of simulated results is under progress.
