Abstract (en)
[origin: EP1936740A1] The antenna (220,320), to measure speeds and distances using the Doppler principle, has a frequency selective antenna surface (240,340) to give two different resonance frequencies. The antenna surface can have an arrangement of periodic apertures (250) or insulated conductive elements (350). A chip (210,310) is coupled to the antenna. A transponder (200,300) acts as a permit for tolls, etc.
