Problems solved by technology

However, in 5G applications, due to the high operating frequency of the antenna and the small size of the antenna, the bottom metal floor is too large compared to the antenna, and the performance of a single ESPAR antenna is limited.

Abstract

The invention discloses an electronically controlled passive array 5G antenna applied to mobile devices, comprising: a plurality of ESPAR antenna units, each ESPAR wire unit is used to generate electromagnetic wave signals with a preset direction; a metal floor, a plurality of ESPAR The antenna units are all connected to the metal floor, and multiple ESPAR antenna units form a phased array antenna on the metal floor according to the required gain and direction. The present invention has the following advantages: under the premise of realizing beam scanning, the system complexity and cost can be greatly reduced; in conjunction with the beam scanning of the ESPAR antenna itself, beam forming can be performed more conveniently by using different unit feed amplitude and phase control.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an electronically controlled passive array 5G antenna applied to mobile devices. Background technique [0002] The fourth-generation mobile communication technology has matured. Based on the premise that the next-generation (5G) mobile communication standard has not yet been determined, the research on antenna technology on mobile devices is first carried out. At present, 5G technology is more likely to adopt millimeter wave technology. For mobile terminals, it is necessary to use array antennas to increase the gain of space electromagnetic waves in a certain direction. However, for mobile terminal equipment and wireless routers, the traditional phased array form has high complexity and higher cost. [0003] The existing electronically controlled passive array antenna (Elecironically Steerable Parasitic Array Radiator Antenna, ESPAR) antenna is based on the followin...
