The coupling assembly rotates about the center of the arc conductor assembly, and the arc conductor assembly comprises a first arc conductor and a second arc conductor. The first arc conductor and the second arc conductor are arranged in a circle around the center of the circle, one of the first arc conductor and the second arc conductor is a slow wave structure, and two ends of the first arc conductor and two ends of the second arc conductor are each provided with an output port. When the coupling assembly is located at a first position, the coupling assembly is coupled and electrically connected to the first arc conductor, and when the coupling assembly is located at a second position, the coupling assembly is coupled and electrically connected to the second arc conductor. The switchable beam phase shifter provided by the present application may switch between the two working states of a wide beam and a narrow beam by means of the coupling connection between the coupling assembly and different arc conductors, and has good impedance matching and relatively high practicality.

Provided in the present application are an array antenna and a mobile terminal. In the present application, by providing multiple columns of array elements to increase the number of array elements, the maximum gain reduction of an array antenna in a maximum scanning region is reduced. Furthermore, by configuring each feed network to support a 28 GHz frequency band and a 39 GHz frequency band, 2*2 MIMO signal differentiated communication for each array element is achieved, so that the array antenna supporting a dual-frequency dual-polarized signal is achieved. Meanwhile, the antenna array can be automatically adjusted according to signal strength to reduce input power, thereby increasing the operating energy efficiency of the system and dynamically adjusting the operating temperature of a chip.

A monopole antenna coupled to a metallic ground plane includes apertures used to steer a radio frequency (RF) beam of the monopole. The apertures may have a length, width, and distance from the monopole based on the wavelength of the RF signal used to drive the monopole antenna. The aperture may be coupled to one or more selective devices, such as PIN diodes, which may short portions of a metallic ground plane near the aperture. The shorted portions of the metallic ground plane provide for steering of the monopole radiation pattern. A circuit board metallic ground plane may include multiple apertures to direct different RF signal frequencies from a single monopole antenna. Multiple monopole antennas may be implemented over a metallic ground plane within a wireless device, each monopole antenna with corresponding apertures.
