Abstract:
1. An electronic device adapted to perform a wireless communication for a transmission of data, the electronic device comprising: a housing for the electronic device having a recess provided therein; at least a first antenna having a first antenna feed point and a second antenna having a second antenna feed point; the first and second antennas connected to the electronic device by the first and second antenna feed points, respectively; the first and second antennas configured to transmit and receive electromagnetic signals for providing the wireless communication using a multiple antenna communication scheme that is based on multiple spatial transmission paths; an extension mechanism to which at least the first antenna is mounted; the extension mechanism having a retracted position and at least one extended position; wherein a distance between the first antenna feed point and the second antenna feed point is larger in the extended position than in the retracted position; the extension mechanism comprising a sliding element slidably arranged in the recess of the housing; wherein, in the retracted position of the extension mechanism, the sliding element is substantially arranged inside the housing; wherein, in the extended position of the extension mechanism, the sliding element projects from a contour of the housing; wherein the extension mechanism is configured to have a plurality of extended positions each corresponding to a different distance between the first antenna feed point and the second antenna feed point; the plurality of extended positions including a first extended position; wherein the extension mechanism comprises an actuator configured to receive a control signal and, in accordance with the control signal, bring the extension mechanism from the retracted position into the first extended position; a controller configured to control operation of the extension mechanism by providing the control signal to the actuator; wherein the control signal determines the first extended position into which the extension mechanism is to be brought in order to adjust the distance between the first antenna feed point and the second antenna feed point.
