ABSTRACT:
A radiation device having a L-shaped ground plane. The radiation device comprises a radiation patch; a feeding-in device for exciting the radiation patch; and a L-shaped ground plane. The L-shaped ground plane has a first ground plane and a second ground plane, and the first ground plane is parallel to the radiation patch and an included angle is formed between the fist and the second ground plane. The feeding-in device is used for coupling the energy to the radiation patch, and is connected to the first ground plane of the L-shaped ground plane.
