Abstract : This rapid evaluation shows use of structured metamaterial (MTM) in microstrip patch antenna design for improvement of antenna performance. In recent years, the demand for antenna size reduction and integration with many of telecommunication equipment is of great interest, widely and rapidly used system such as communication systems like mobile, smart phones, GPS, wireless Internet devices, etc. for satisfying demands, the wireless device and their components must be compact and capable of multifunction, multifrequency band operation.
