Reconfigurable antenna system
The invention relates to a reconfigurable antenna system (1), which comprises a plurality of antenna units (10) and does not employ phase shifters. Each antenna unit (10) is by itself a reconfigurable antenna having at least an active radiating element which is coupled to one or more passive radiating elements. Each antenna unit is provided with one or more variable loads (12) that can be electrically connected/disconnected to each other and with said antenna unit (10), to selectively configure the radiating properties of the system. A bias network (70) is adopted to bias the variable loads (12) and a control unit (80) allows controlling the operation of said bias network (70). Each active radiating element is fed by at least a feeding line (501) that provides it with a suitable polarization. Hence, the system can advantageously resort to multiple polarizations, each of them being provided by a same source. Preferably, each active radiating element receive its feeding signal from the source/s by means of power dividers (60) and/or switches. Preferably, each antenna unit is covered by at least a radiating structure, comprising a plurality of passive radiating elements, which does not affect the reconfigurability of the antenna unit itself and increases the overall antenna gain. The antenna system is then characterized by remarkable beam-steering capabilities and high gain, avoiding the losses and complexities related to phase shifters and overcoming the typically small antenna gain values of current reconfigurable antenna systems.

MULTI-BEAM METASURFACE ANTENNA
A multibeam antenna and method of using the same are described. In one embodiment, the antenna comprises an aperture having a plurality of radio-frequency (RF) radiating antenna elements. The RF radiating antenna elements generate a plurality of beams simultaneously in different directions in response to a first modulation pattern for holographic beamforming applied to the plurality of RF radiating antenna elements to establish all beams of the plurality of beams such that antenna elements of the plurality of RF radiating antenna elements contribute to all beams in the plurality of beams concurrently. The antenna also includes a controller coupled to the aperture to generate the first modulation pattern.
Scanning antenna
A scanning antenna is provided in the present disclosure. The scanning antenna includes a first substrate and a second substrate which are arranged oppositely; a liquid crystal layer between the first substrate and the second substrate; and a feed signal access terminal and a plurality of phase shift units, where the plurality of phase shift units is connected with each other, each phase shift unit is connected to the feed signal access terminal, and electrical lengths between at least two phase shift units and the feed signal access terminal are different. The present disclosure not only realizes one-dimensional wave beam scanning, but also has desirable scanning effect. The bias voltage is not needed to be independently applied to each phase shift unit, which can greatly simplify the bias voltage line configuration and be beneficial for reducing production cost and wiring difficulty.
