Abstract: A dipole antenna with reduced feedline reverse current is provided. A substrate includes a first surface and a second surface, with a feed aperture and a ground aperture penetrating through both the first and second surfaces. A radiator is configured on the first surface for receiving and transmitting wireless signals. A feeder configured on the second surface connects the radiator through the feed aperture. A ground portion with a main notch is configured on the second surface and connects the radiator through the ground aperture. A feedline passing the main notch has an end connecting to the feeder and the ground portion. The reverse current of the feed line is absorbed by the ground portion around the main notch.
