A properly modulated carrier signal exits transmission circuitry (,) and enters a first and a second mixer (,). The modulated carrier is mixed with a first and a second function by the first and the second mixers (,). The functions are generated by a first and a second signal generator (,). The mixed signals exit the mixers (,), and are amplified (via amplifiers,), to be radiated by an antenna (,). The antenna (,) comprises two orthogonal antenna elements (,), that are in close proximity with one another (although not in contact). One of the mixed signals is radiated on a first element (,), and the other mixed signal is radiated on the second element (,). The resulting signal transmitted from the antenna (,) is the original carrier signal having the plane of polarization constantly changing. Thus a reflected signal emitted an instance earlier cannot interfere with a wave currently emitted.
