TWO-DIMENSIONAL RADIATION PATTERN RECONFIGURABLE ANTENNA SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/137015
Kind Code:
A1
Abstract:
Disclosed is a two-dimensional radiation pattern reconfigurable antenna system, comprising an antenna element array module for transmitting and receiving a signal; a Butler matrix module for forming horizontal and vertical beam characteristics before the antenna element array module transmits the signal and being composed of 3dB bridges; and a phase shifter module for transmitting an input signal provided by a feed network or a transceiver and providing the input signal to the Butler matrix module, the phase shifter module comprising at least one phase shifter with equal power allocated thereto, wherein the phase shifter module is provided with one input port and four output ports; the Butler matrix module is provided with multiple input ports and multiple output ports; the four output ports of the phase shifter module are all connected to the input ports of the Butler matrix module; and the output ports of the Butler matrix module are connected to the antenna element array module. The antenna system of the present invention has an adjustable beam width and a simple structure, and is easy to realize.
