The smart dynamic
radiation pattern optimising
system is a design and technique to actively shape & optimise the
radiation pattern of
mobile device controlled by smart RF / Antenna
system with
signal processing algorithm that works by sensing the change in device proximity environment with nature or property, range, orientation, position, location,
signal quality parameters and
ambient intelligence to protect the user by controlling
radiation exposure, enhance RF
signal quality and to save battery power. Mobile devices are handled in different proximity environment which influence the antenna performance due to
electromagnetic interaction based on environments properties that leads to detuning,
radiation pattern distortion, impedance mismatch etc which in turn degrades the
signal quality. Also change in device orientation according to usage leads to
power loss due to polarization mismatch. So when the
signal quality degrades the
system will sense & compute in an adaptive
closed loop manner to actively optimise the
radiation pattern according to scenarios. The design consist of (a) a
sensor system 220 to determine the change in proximity environment [close vicinity] with sensing its property, sensing multi-direction, dimension, layer, position & range of proximity environment with respect to device, sensing device (antenna) orientation, visual sensing,
infrared or thermal vision, user recognition, user head & hand hold effect, location, usage scenarios & operating
modes and accordingly generate the trigger signal 230; (b) a
processing unit 150 for computing the interrupt
control signal 140 according to the nature of trigger signal & existing
signal quality parameters; (c) Smart active
radiation pattern optimiser 120 that works based on
control signal; (d) Antenna system 110 capable of achieving dynamic radiation pattern coupled with radiation pattern optimiser that actively shapes and controls the radiation pattern accordingly to protect the user and also restores radiation according to scenarios to optimise communication. Other aspects of the present invention are the same
sensor system 220 is utilised to develop an application that guides the user locate & position the
mobile device in
living space to achieve optimised performance, protect the
mobile device from theft and
ambient intelligence to alert & interact with the user.
