Abstract:
An antenna for testing mobile phones of the type having a protruding antenna, comprising:a hollow cylinder of electrically insulating material for surrounding a portion of the protruding antenna during testing;a first, electrically conductive film portion mounted around a peripheral surface of the hollow cylinder, wherein the first, electrically conductive film includes a first band portion extending in a circumferential direction around a peripheral surface of the hollow cylinder; andan integral matching network which includes a second, electrically conductive film portion mounted around a peripheral surface of the hollow cylinder and electrically connected to the first, electrically conductive film portion, wherein the second, electrically conductive film portion includes a finger portion extending from the first band portion in a direction parallel to an axis of rotation of the hollow cylinder, the finger portion tapering to a point at a location furthest from the first band portion, and a second band portion having a width that is smaller than the width of the first band portion, the second band portion extending from the point of the finger portion in a circumferential direction only partially around the peripheral surface of the hollow cylinder.
