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 a T-shaped slot, an L-shaped slot and a reversed-L-shaped slot, wherein the L-shaped slot and the reversed-L-shaped slot are mirror-reflected to each other.
Claims21
A microstrip antenna having a slot structure, said microstrip antenna comprising:
- a base board having a first surface and a second surface, wherein said first surface is parallel to said second surface;
- and
- a microstrip patch radiator formed on said first surface of said base board, wherein said microstrip patch radiator has said slot structure exposing a portion of said base board, said slot structure having:
- a T-shaped slot composed of a first linear slot and a second linear slot, wherein said first linear slot is vertical to a side of said microstrip patch radiator, and vertically connects said side to a middle position of said second linear slot;
- an L-shaped slot, wherein one end of said L-shaped slot is vertically connected to one end of said second linear slot, and the opening direction of said L-shaped slot faces towards said first linear slot;
- and
- a reversed-L-shaped slot, wherein one end of said reversed-L-shaped slot is vertically connected to the other end of said second linear slot, and the opening direction of said reversed-L-shaped slot faces towards said first linear slot, and said L-shaped slot and said reversed-L-shaped slot are mirror-reflected to each other.
The microstrip antenna comprising:
- a base board having a first surface and a second surface, wherein said first surface is parallel to said second surface;
- and
- a micro strip patch radiator having an arc shape, wherein said micro strip patch radiator is formed on said first surface of said base board, and has said slot structure exposing a portion of said base board, said slot structure having:
- a substantial T-shaped slot composed of a first arc slot and a second arc slot, wherein said first arc slot is substantially vertical to a side of said microstrip patch radiator, and vertically connects said side to a middle position of said second arc slot;
- a first hook-shaped slot, wherein one end of said first hook-shaped slot is vertically connected to one end of said second arc slot, and the opening direction of said first hook-shaped slot faces towards said first arc slot;
- and
- a second hook-shaped slot, wherein one end of said second hook-shaped slot is vertically connected to the other end of said second arc slot, and the opening direction of said second hook-shaped slot faces towards said first arc slot.
