Abstract: An active-passive integrated antenna is provided. The active-passive integrated antenna includes a reflective plate, a pair of mounting portions respectively secured to two sides of a bottom of the reflective plate, a dielectric plate, a plurality of passive antenna elements and an active antenna unit. More specifically, the dielectric plate is spaced apart from the reflective plate on the pair of mounting portions, and a first surface of the dielectric plate is provided with a frequency selection surface; the plurality of passive antenna elements are respectively arranged on the reflective plate and the frequency selection surface; the active antenna unit is arranged above a second surface of the dielectric plate and secured to the pair of mounting portions.

Abstract: An apparatus for reducing the wind resistance of an antenna is provided. The apparatus includes a radome, an upper end cap and a lower end cap disposed on the upper and lower ends of the radome. The radome includes a windward surface, and at least one of the upper end cap or the lower end cap includes a bottom edge and a front contour surface. The front contour surface is formed by extending and bending from a portion of the bottom edge close to the windward surface in a longitudinal direction toward the center of the upper end cap or the lower end cap.

Abstract: An end cover includes an end cover plane perpendicular to a longitudinal axis of a radome and passes through a connection part of the end cover and the radome. Outlines of a cross section of the end cover includes a first spline curve between a first end point and a first intermediate point having at least one first curvature, and a second spline curve between a second intermediate point and a third intermediate point having at least one second curvature. The first intermediate point and the second intermediate point are not in the end cover plane. A distance between the first intermediate point and the end cover plane and a distance between the second intermediate point and the end cover plane are equal and not less than a distance between any point on the cross section of the end cover and the end cover plane.

Abstract: A phase shifter assembly includes: a first phase shifter including a first through-hole; a second phase shifter including a second through-hole and disposed at a side of the first phase shifter; a first gear including a third through-hole and disposed at a side of the second phase shifter facing away from the first phase shifter; a rack configured to drive, through driving the first gear, the second phase shifter to move relative to the first phase shifter, to adjust an electrical tilt angle of an antenna corresponding to the phase shifter assembly; and a first reversing mechanism disposed between the first gear and the rack and engaged with the first gear and the rack, respectively, making a direction of a component of a linear velocity at an electrical contact between the first phase shifter and the second phase shifter in a moving direction of the rack is opposite to the moving direction of the rack.
