Title:
ANTENNA ASSEMBLY AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/100566
Kind Code:
A1
Abstract:
The present application provides an antenna assembly and a communication device, for use in enabling an antenna assembly to support beam scanning within a large range. The antenna assembly comprises a lens, a guide rail, an antenna array, and a phase shifter. The lens has a first refractive surface and a second refractive surface. The guide rail is a linear guide rail located on one side of the first refractive surface of the lens. The antenna array comprises a plurality of radiating elements. The antenna array is slidably connected to the guide rail. As the antenna array moves on the guide rail, beam orientations of the antenna assembly move along the extension direction of the guide rail, such that mechanical beam scanning is performed within a first scanning range in the extension direction of the guide rail. The phase shifter is connected to the plurality of radiating elements to adjust feed phases of the plurality of radiating units, such that when the antenna array is at different positions on the guide rail, phase modulation scanning is performed within a second scanning range by adjusting the feed phases of the radiating elements.
