    摘要: A calibration circuit board for an antenna. The calibration circuit board may include: a first metal layer configured to be grounded; a first substrate over the first metal layer; a second substrate over the first substrate; and a plurality of couplers. Each coupler may include: a transmission line provided with an input port and an output port at both ends thereof, respectively; and a coupling line coupled with the transmission line and including two first portions respectively located at both sides of the transmission line, and a second portion connected between the two first portions. The coupling lines may be connected in series to provide a first calibration port and a second calibration port. One of the transmission lines and the coupling lines may be between the first substrate and the second substrate, and the other of the transmission lines and the coupling lines may be over the second substrate.

    摘要: The present invention relates to an antenna assembly for a beamforming antenna, comprising a reflector and an antenna array that includes a plurality of first radiating elements that are arranged as a first vertically extending array, the first radiating elements extending forwardly from the reflector; and a plurality of second radiating elements that are arranged as a second vertically extending array, the second radiating elements extending forwardly from the reflector. Two adjacent first radiating elements are spaced apart from one another by a first distance, and a first radiating element and an adjacent second radiating element are spaced apart from one another by a second distance. The first distance is substantially equal to the second distance. The antenna assembly further comprises a plurality of parasitic elements that are placed along sides of the first and second of the vertically extending arrays.

    摘要: An integrated base station antenna comprises a passive antenna that includes a front radome, a matching dielectric layer and a rear radome; and an active antenna mounted on the back of the passive antenna. A distance between the rear radome of the passive antenna and the matching dielectric layer is a first distance, and the distance between the active antenna and the rear radome of the passive antenna is a second distance, where the first distance is selected as 0.25 + n/2 times the equivalent wavelength, where n is a positive integer, and the second distance is selected as 0.25 + N/2 times the equivalent wavelength, where N is a natural number. The equivalent wavelength is within the range of 0.8 to 1.2 times of the wavelength corresponding to a center frequency of an operating frequency band of the radiating elements in the active antenna.
