Development of wideband phased array antenna

Wideband communication system covering the range from 4 to 8 GHz requires compact antenna to provide desirable characteristic over whole operating band. This project consists of two designs; first design is presented with optimum geometry of an ultra wideband circular patch antenna. To achieve an UW...
