A wireless communication device is provided. The wireless communication device includes a circuit substrate, an antenna cover, a first antenna array and a first power divider. The first antenna array is arranged between the circuit substrate and the antenna cover. The first antenna array includes two first antenna elements and two second antenna elements. The first antenna elements are disposed on a first surface of the circuit substrate. The second antenna elements are arranged on the antenna cover and correspond to the first antenna elements, respectively. Each of the second antenna elements and a corresponding one of the first antenna elements are separated from and coupled to each other. In response to the two first antenna elements being fed with a first signal provided by a signal source from the first power divider, the first antenna array is configured to generate a radiation pattern having a first polarization direction.

Wireless communication device

A reflector structure is configured to connect an antenna. The antenna has an excitation source. The reflector structure includes a metal substrate, at least one first flat plate and a second flat plate. The metal substrate is configured to reflect the radiation of the antenna. The at least one first flat plate is disposed on the metal substrate. The second flat plate is floated to the metal substrate along a virtual normal and completely separated from the at least one first flat plate to form a closed slot. A cavity is formed by the metal substrate, the at least one first flat plate and the second flat plate and communicated with the closed slot. The excitation source is projected onto a plane to form an excitation source region. The excitation source region is located in the second flat plate.

Reflector structure and antenna device

An antenna structure includes a substrate, a first polarization antenna group, and a second polarization antenna group. The substrate is defined with a first axis and a second axis. The first polarization antenna group and the second polarization antenna group are disposed on the substrate. The first polarization antenna group includes a first dipole antenna, a second dipole antenna, and a first wire. The first wire is separate from and coupled to the first dipole antenna and the second dipole antenna. The second polarization antenna group includes a third dipole antenna, a fourth dipole antenna, and a second wire. The second wire is separate from and coupled to the third dipole antenna and the fourth dipole antenna.
