Abstract
An antenna system with a reconfigurable radiation pattern characteristic for the fifth generation (5G) mobile terminal is described, which includes multiple antenna sub-arrays with different radiation patterns and a switch that connects each antenna sub-array and controls switching between different antenna sub-arrays. A switch is disposed between the antenna sub-arrays and an RF front-end module. By switching between the different sub-arrays, the radiation in a desired direction can be selected. Therefore, the problem of the beam coverage and beam scanning blind spot of 5G terminal antenna in millimeter waveband can be solved effectively. Through expanding the scanning angle of the beam scanning, the scheme of 5G terminal antenna with a reconfigurable radiation pattern can be realized. The antenna structure of this disclosure makes full use of the space of the PCB board, and has the advantages of miniaturization, simple processing and compact structure, etc.
