Patent ID: 7489280

Claim:
Antenna module for frequencies in the GHz range and mountable on a motor vehicle, comprising: a) a lower patch-antenna including: i) a lower substrate including a dielectric material; ii) a lower λ/2-antenna structure provided on an upper surface of the lower substrate for reception of satellite transmitted frequencies in the GHz range; and iii) a lower metallization provided on a lower surface of the lower substrate; b) an upper patch-antenna provided on the lower patch-antenna, including: i) an upper substrate including a dielectric material; ii) an upper λ/2-antenna structure provided on an upper surface of the upper substrate for reception of satellite-transmitted frequencies in the GHz-range; and iii) a metallization provided on a lower surface of the upper substrate; c) a lower antenna connector running from the lower λ/2-antenna structure through the lower substrate; and d) an upper antenna connector separate from the lower antenna connector, and running from the upper λ/2-antenna structure through the upper substrate and the lower patch antenna; and e) the upper patch antenna being of smaller dimensions than those of the lower patch-antenna.
