Patent attributes
A printed antenna includes a radiation part (10) for radiating and receiving electromagnetic signals, a feed wire (30) for feeding the electromagnetic signals to the radiation part, a matching part (20) for impedance matching, and a ground plane (40). The radiation part includes a first radiation segment (12), a second radiation segment (14), and a third radiation segment (16). The second radiation segment is electrically connected to the first radiation segment and the third radiation segment. The feed wire is electrically connected to the radiation part. The matching part is electrically connected to the radiation part and the ground plane. The second radiation segment and the matching part extend from the first radiation segment to a same side of the first radiation segment.
