Problems solved by technology

Therefore, when the array antenna in the prior art is applied to various radio wave environments such as RFID, it is difficult to adapt to each environment by changing the number of antenna elements, the space between antenna elements and the arrangement form to achieve the optimum performance
Therefore, the optimal beam pattern for various radio wave environments has not yet been formed

Abstract

An array antenna system including: a base frame; a plurality of antenna elements which is arranged on the base frame; a driving unit which provides a driving power to each of the plurality of antenna elements when the plurality of antenna elements is moved or transformed on the base frame; a sensor unit which senses a change of a radio wave environment; and a control unit which transmits a driving signal to the driving unit according to a change of the radio wave environment, the change of the radio wave environment being sensed by the sensor unit.

Description

technical field [0001] The present invention provides an array antenna system that automatically adjusts the space between arrayed antennas, and more specifically, provides an array antenna system that automatically changes the space and arrangement of antenna elements according to changes in the radio wave environment . Background technique [0002] In an array antenna, a plurality of antenna elements are arranged and the excitation current phase of each antenna element is adjusted. Also, in an array antenna, each antenna element is set in a specific azimuth and phase and thus a main beam is formed. Currently, array antennas are applied to various radio wave environments such as radio frequency identification (RFID: radio frequency identification) technology and the like. [0003] In this type of array antenna, the number of antenna elements, the space between antenna elements, and the arrangement form are required to be designed according to the installation location and...
