M.TECH PROJECT:

Title:- Single layer Radom Analysis using Reflectarray Antenna
Abstract:-
A double layer stacked square patch reflectarray antenna is designed at w-band (94 GHz). The antenna has shown high gain, low cross polarization, and large
bandwidth. The proposed antenna has a simulated maximum gain of 31.7 dB at 94 GHz. A 4.25 % bandwidth is achieved in the frequency band of 92-96 GHz with 1.5 dB gain variation. Half power beam width of the reflectarray is as narrow as 2°.
