Claim 11:
12. A vehicle comprising:
a frame comprising a metal panel forming an exterior surface of the vehicle;
an antenna disposed directly below the metal panel in an interior of the vehicle, wherein the antenna is occluded by the metal panel;
a printed circuit board (PCB) module electrically connected to the antenna, wherein the PCB module comprises a ground region, a control unit, a first switch and a second switch;
a first ground extender arranged at a first ground location within the ground region to electrically connect a ground of the PCB module to a first location of the metal panel located directly above the first ground location; and
a second ground extender arranged at a second ground location within the ground region to electrically connect the ground of the PCB module to a second location of the metal panel located directly above the second ground location,
wherein the first ground location is isolated from an other ground region by fill-cut, and the second ground location is isolated from the other ground region by the fill-cut,
wherein the first ground extender is connected to the first switch, and the second ground extender is connected to the second switch,
wherein the control unit configured to receive a request to change a frequency to a target frequency from a broadcasting receiver, and to control at least one of the first switch or the second switch so that a current flows to the first ground extender or the second ground extender corresponding to the target frequency,
wherein the metal panel is continuous and forms a substantially common plane from directly above the antenna to the first location and the second location, and
wherein the antenna and the metal panel are configured to perform capacitive coupling.
