Multi -antenna system's controlling means

The utility model provides a multi -antenna system's controlling means, belongs to the communication technology field. System and electronic communication device electrically connect include: multi -antenna system, the power antenan unit, wireless module and microprocessing unit, power antenan unit and multi -antenna system electrically connect, wireless module and power antenan unit electrically connect, microprocessing unit and power antenan unit and wireless module electrically connect, it judges the logic to have signal intensity in the microprocessing unit, by the multi -antenna system wireless radiofrequency signal of receipt and on power antenan unit conveying to wireless module, wireless module reaches microprocessing unit with received signal, judge with signal intensity that signal intensity that the logical decision was received hangs down or is higher than a default by microprocessing unit, join in marriage the logic calculus method and handle the back, this multi -antenna system's radiation field pattern is changed with this power antenan unit of input signal control. Can integrate existing radio communication module simply, make multi -antenna system's design more simple and convenient.
