Abstract
A substrate has a front face and a back face. A first antenna and a second antenna are arranged on the front face in interlaced manner such that a first signal feeding point of the first antenna and a second signal feeding point of the second antenna are arranged on the same face or the same location. A ground face is arranged on the back face of the substrate and opposite to the first antenna and the second antenna. A cross-connect element is fixed on the ground face and electrically connected to the second antenna. The first antenna and the second antenna become a dual polarization array antenna structure for providing multi-band operation when receiving or transmitting a signal flowing through a first metal wire or a second metal wire at a length of a half of a wavelength of the signal.
