Abstract
The utility model discloses a miniature high-gain microstrip antenna which comprises a radiation body and a reflection body. The radiation body is composed of a horizontal radiation surface and a perpendicular radiation surface. The reflection body is composed of a horizontal reflection surface and a perpendicular reflection surface. Both the radiation body and the reflection body are made of metal material. The perpendicular radiation surface is disposed between the horizontal radiation surface and the horizontal reflection surface. The perpendicular radiation surface is electrically conductively connected with the horizontal radiation surface at an end of the horizontal radiations surface, the two radiation surfaces being not in mutual contact. The perpendicular reflection surface is arranged between the horizontal radiation surface and the horizontal reflection surface, wherein the perpendicular reflection surface and the horizontal reflection surface perpendicularly intersected with one another; and the perpendicular reflection surface is not in contact with the radiation body. According to the miniature high-gain microstrip antenna, width in the radiation direction is expanded, and thus the antenna has a larger radiation range. Furthermore, the size of the antenna can be reduced, the cost can be saved, and convenience in installation is brought to clients.
