ABSTRACT:
An EMC (electromagnetic compatible) antenna having a shielding metal wall to effectively reduce the possible coupling with nearby electronic elements is presented. The antenna includes: a ground plane, a bent ground plate, and a radiating plate. The bent ground plate is vertically connected to the ground plane and functions as an effective shielding metal wall to eliminate or greatly reduce the possible EM coupling between the antenna and nearby electronic elements. The radiating plate is used to generate the operating resonant mode of the antenna and is generally parallel to the ground plane. The radiating plate is also electrically connected to and encircled by the bent ground plane.
