Abstract: A near-eye display device is disclosed that includes a pixel display configured to display multiple groups of pixels, in each frame of image, that are output by scanning. The device includes multiple semi-reflectors, where each semi-reflector is in a one-to-one correspondence with each group of pixels displayed by the pixel display unit. Each semi-reflector includes multiple inner platings that are disposed at different reflection angles. Each of the inner platings is in a one-to-one correspondence with each pixel subunits that is in a group of pixels corresponding to a semi-reflector in which the inner plating is located. Each semi-reflector is configured to be activated when the group of pixels corresponding to the semi-reflector is reflected, and reflect each pixel subunit which is in a one-to-one correspondence with each of the inner platings to a direction of an eyeball center by using all the inner platings included in the semi-reflector.

Abstract: A method for returning a base station signal and a base station for implementing the method. The base station includes a first return unit located in a radio frequency system and a second return unit located in a baseband processing system. The first return unit is configured to perform analog modulation on an uplink analog signal of a first bandwidth to obtain an uplink analog signal of a second bandwidth, and send the uplink analog signal of the second bandwidth to the second return unit, where the second bandwidth is larger than the first bandwidth. The second return unit is configured to receive the uplink analog signal of the second bandwidth, demodulate the uplink analog signal of the second bandwidth to obtain the uplink analog signal of the first bandwidth.

Abstract: A beam steering antenna structure comprises a stacked antenna module and a first conductive component. The antenna module comprises a first substrate and a second substrate arranged superjacent such that main planes of the substrates extend in parallel. The first substrate comprises a first antenna array transmitting and receiving a first radiation beam. The second substrate comprises a second antenna array transmitting and receiving a second radiation beam. The first conductive component extends adjacent to the antenna module and is at least partially separated from the antenna module in a first direction perpendicular to the main plane of the conductive component. The antenna module is coupled to the conductive component by means of at least one of a galvanic, capacitive, or inductive coupling. At least one of the first and the second radiation beams is at least partially steered away from the other one by the first conductive component.
