ABSTRACT:
A planar antenna disposed on a substrate (100) includes a metallic ground plane (200), a radiating part (300), an open-short transforming part (400), a joint portion (700), and a feeding part (500). The metallic ground plane is laid on the substrate. The radiating part transmits and receives radio frequency (RF) signals, and includes a first bent portion (320) and an open end (310). The first bent portion is electrically connected to the open end. The open-short transforming part is electrically connected between the radiating part and the metallic ground plane, and includes a second bent portion (430). The joint portion connects the open-short transforming part and the radiating part, and defines a recessed portion (701). The feeding part is electrically connected to the joint portion, for feeding signals.
