Microstrip antenna is well suited for many applications because of its properties like lightweight, planar structure and ease of fabricating, however it has limitation of low band width and gain. In this paper, a design technique for enhancing gain of microstrip patch antenna in ultra wide band frequency spectrum is proposed. This paper presents the design of series fed microstrip patch antenna array with meta-material. The advantage of this antenna is that it provides an overall planar structure. This antenna may find application in modern communication systems and radar systems.
