ABSTRACT:
A microstrip antenna having a slot structure is disclosed for providing a sufficient bandwidth so as to meet the antenna requirements. The microstrip antenna is composed of a base board (such as a printed circuit board) and a microstrip patch radiator having the slot structure, wherein the microstrip patch radiator is formed on the base board. The slot structure is composed of an L-shaped slot and an inverted reversed-L-shaped slot, wherein the L-shaped slot and the inverted reversed-L-shaped slot are mirror-reflected to each other symmetrically to a point. One end of each of the L-shaped and inverted reversed-L-shaped slots is connected to an extension slot.
