Abstract:
1. An antenna system comprising: an antenna; a tuner including a series inductance and a parallel capacitance; a transfer unit for transferring radio frequency signals between the antenna and the tuner, the transfer unit including a reactive element comprising a variable series capacitance and a shunt inductance connected to system ground, the transfer unit further comprising a switch connected between the tuner, the antenna, and the reactive element; and a control unit adapted to control the switch to operate in a first configuration to bypass the reactive element in an electrical connection between the tuner and the antenna when a frequency of the radio signals is above a predetermined value and further adapted to control the switch to operate in a second configuration to connect the reactive element between the tuner and the antenna when the frequency of the radio signals is below the predetermined value.
