Electronic apparatus, system and method

A system comprising:

• an electronic apparatus configured to transmit a beam of a first wireless signal from a plurality of antennas;
• a power receiving apparatus configured to transmit a second wireless signal and receive power supplied by the beam of the first wireless signal;
• and
• said electronic apparatus further configured to receive the second wireless signal from the plurality of antennas, detect an object located between the electronic apparatus and the power receiving apparatus in a direction of the beam based the second wireless signal received at the plurality of timings, and change a shape of the beam in relation to the object based on the propagation path information by controlling at least either an amplitude or a phase of the first wireless signal provided to each antenna of the plurality of antennas.

A method comprising:

• a power transmission apparatus transmitting a beam of a first wireless signal from a plurality of antennas;
• a power receiving apparatus receiving power supplied by the beam of the first wireless signal;
• the power receiving apparatus transmitting a second wireless signal;
• the power transmission apparatus receiving the second wireless signal with the plurality of antennas;
• the power transmission apparatus detecting an object located between the plurality of antennas and the power receiving apparatus in a direction of the beam based on the second wireless signal received at the plurality of timings;
• the power transmission apparatus changing a shape of the beam in relation to the detected object based on the propagation path information by controlling at least either an amplitude or a phase of the first wireless signal provided to each antenna of the plurality of antennas.
