Abstract (en)
[origin: EP1108616A2] A planar microstrip antenna suitable for motor-vehicle systems operating in dual-band resonance frequency. it comprises a radiant element (1), a mass plane (2) parallel to said radiant element (1), a shorting lead (3) that connects said radiant element to said mass plane, and feeding means fixed to a coaxial cable (8). Said radiant element (1) has a configuration proportioned for a first resonance frequency, and is provided with at least a slot (6) located in proximity with and parallel to its edge (5). Said slot has a proportional extension according to the resonance frequency desired. <IMAGE>
