Lightweight microstrip patch radiators

Microstrip Patch Radiators for X- Band antennas have been developed.. The radiator provide an excellent RF performance ,ultra-low weight and low cost technology.The technology is qualified considering space flight environment such as outgassing, vibration, UV-radiation, particle radiation, etc. . Different array configurations were built such as (1x8), (8x8) and (16x16).
