Abstract: An antenna for wireless communications includes a horizontal polarization antenna and a vertical polarization antenna that are disposed in a stacked manner. The horizontal polarization antenna includes a radiation element and a double-sided parallel strip line. One end of the double-sided parallel strip line is connected to the radiation element. A length range of the double-sided parallel strip line is 0.58 to 1.35 times a waveguide wavelength of an electromagnetic wave in the double-sided parallel strip line at an operating frequency of the vertical polarization antenna.

Abstract: A dual-band antenna, a wireless local area network (WLAN) device, and a method for manufacturing a dual-band antenna, where the dual-band antenna includes a conductive plane, a smooth curved-surface assembly joined onto the conductive plane, and a feed pin connected to the smooth curved-surface assembly. The conductive plane is configured to function as a first antenna, for receiving and sending a radio frequency signal of a first frequency band, and the smooth curved-surface assembly is configured to function as a second antenna, for receiving and sending a radio frequency signal of a second frequency band. Hence, a curved surface of a surface of the curved-surface assembly that is used as the second antenna transits smoothly. Therefore, a current is distributed relatively evenly, and radiation efficiency is relatively high.

CPC classification number: H01Q21/205 , H01Q9/16 , H01Q19/24
Abstract: An antenna device includes a plurality of dipole antennas and a port. Each of the dipole antennas is connected to the port. The dipole antennas are arranged around the port. Each of the dipole antennas comprises two ends. The device further includes a plurality of passive elements. The ends of the dipole antennas and the passive elements are interchangeably arranged around the port such that each of the passive elements is situated between ends of two different antennas from the plurality of dipole antennas. One or more switches are configured to switch between an omnidirectional state, in which the ends of the dipole antennas are not connected to the plurality of passive elements, and a directional state, in which at least one end of one of the passive elements is connected to at least one end of one of the antennas.
