Antenna with radiation pattern reconfigurable

Abstract

The embodiment of the invention provides an antenna with the radiation pattern reconfigurable. The antenna with the radiation pattern reconfigurable comprises a Butler matrix module, a phase shift feed network module and an antenna oscillator array; the Butler matrix module is electrically connected with the phase shift feed network module, and the Butler matrix module or the phase shift feed network module is electrically connected with the antenna oscillator array, wherein the Butler matrix module is used for outputting multipath feed signals; the phase shift feed network module is used for regulating the phase of each path of feed signals in the multipath feed signals; the multipath feed signals with the phase adjustable feed a plurality of antenna oscillator units, the beam width of the antenna radiation pattern varies with the phase of the multipath feed signals, and the inclined angle of the antenna radiation pattern varies with the phase of the multipath feed signals. By means of the antenna with the radiation pattern reconfigurable, the antenna can adapt to a building with a complicated layout, and the building can be effectively covered.

Description

Technical field [0001] The embodiment of the present invention relates to the field of communication technology, and in particular to an antenna with a reconfigurable radiation pattern. Background technique [0002] With the development of communication technology, the transmitting antenna is an indispensable part of the communication equipment, and the transmitting antenna plays the function of receiving and sending signals. [0003] In the prior art, the radiation pattern parameters of the transmitting antenna are fixed. For example, the horizontal half-power angle of the directional antenna is about 65 degrees, and the vertical half-power angle is about 10 degrees. [0004] However, the current layout of urban high-rise buildings and residential buildings in residential areas is complicated. If the radiation pattern parameters of the transmitting antenna are fixed, the coverage of the transmitting antenna is relatively fixed, and the complex layout cannot be effectively covered. ...

Problems solved by technology

[0004] However, at present, the layout of high-rise buildings in cities and residential buildings in residential areas is complex. If the radiation pattern parameters of the transmitting antenna are fixed, the coverage of the transmitting antenna is relatively fixed, and it cannot effectively cover buildings with complex layouts.
