Abstract:
An antenna having adaptable characteristics in response to a voltage provided by a voltage source, comprising:a ground plane; a first meanderline coupler including a first terminal responsive to a signal when said antenna is operative in a transmitting mode and for receiving a signal when said antenna is operative in a receiving mode, and further including a second terminal; a second meanderline coupler including having a first terminal in electrical connection with said ground plane and further including a second terminal; a horizontal conductor substantially parallel to and spaced apart from said ground plane and in electrical connection with the second terminal of said first meanderline coupler at a first region of said horizontal conductor, and in electrical-connection with said second terminal of said second meanderline at a second region of said horizontal conductor; and a deformable member located so as to alter the distance between said horizontal conductor and said ground plane in response to the voltage, such that the antenna dimensional change effected by the deformable member alters the antenna radiating characteristics.
