Abstract

The invention belongs to the field of wireless communication, and particularly relates to a reconfigurable electromagnetic metasurface biasing method, which at least comprises an array surface formed by a reconfigurable electromagnetic metasurface unit and a biasing circuit unit, and is characterized by comprising a DAC (Digital-to-Analog Converter) module (9), an array bottom surface unit (8), an array top surface unit (10) and a Pin tube (1), and the array bottom surface unit (8) and the array top surface unit (10) are connected through a lead and a via hole. The reconfigurable electromagnetic metasurface biasing circuit is simplified, the number of biasing lines is from o-n2 to o-n, the number of IO interfaces occupied by a rear-end circuit is reduced, and the influence of the biasing lines on the electromagnetic property of a unit is reduced; and the number and the positions of the current-limiting resistors are reduced, and extra microwave loss caused by the current-limiting resistors is avoided.

Description

technical field [0001] The invention belongs to the field of wireless communication, in particular to a reconfigurable electromagnetic metasurface biasing method. [0002] technical background [0003] With the gradual rollout of the 5th generation communication system, the wide application of IOT devices, the proposal of new scenarios such as intelligent manufacturing and smart city, and the rise of new wireless terminals such as drones. Human society has an increasing demand for low-cost, long-distance, and high-speed wireless communication equipment. In order to overcome the signal attenuation caused by space attenuation, high-frequency microwave communication has a very close demand for high-gain beam-tunable antenna systems. The rapid development of digital electromagnetic metasurface technology in recent years provides high-gain beam scanning with low cost and high flexibility, focuses the beam in a certain direction, and tracks the user's position to overcome spatial ...
