ABSTRACT:
A printed dual dipole antenna is disposed in a specific region with a border on a PCB having a first surface and a second surface. The printed dual dipole antenna has a first split dipole antenna along a first operation direction. The first split dipole antenna includes a balun member, a first antenna branch, and a second antenna branch on the first surface of the PCB, and a signal feeding member on the second surface of the PCB. Wherein, at least one of the first antenna branch and the second antenna branch is bent into a bent structure to fit within the specific region. A second split dipole antenna along a second operation direction. Wherein, at least one of the first antenna branch and the second antenna branch is bent into a bent structure to fit within the specific region.
