Abstract (en)
[origin: EP0959525A2] The antenna has at least two radiator elements (5,10) mounted adjacent to each other above a reference potential surface (25), one supplied via an antenna network, the second element connected to the reference potential (80) via e.g. a diode (35) that can be switched between high and low impedance states. The first element is resonant at the operating wavelength and the resonance of the second element can be easily detuned w.r.t. the first. An Independent claim is also included for a radio device.
