Patent ID: 7295167

Claim:
An antenna module for frequencies in the GHz range and mountable on a motor vehicle, the antenna module comprising: a lower patch-antenna including: a lower substrate including a dielectric material; a lower λ/2-antenna structure on an upper surface of the lower substrate for reception of satellite transmitted frequencies in the GHz range; a lower metallization provided on or in contact with a lower surface of the lower substrate; an upper patch-antenna including: an upper substrate including a dielectric material; an upper λ/2-antenna structure on an upper surface of the upper substrate for reception of satellite-transmitted frequencies in the GHz-range, the upper λ/2-antenna structure having a length and a width at least one of which is less than the corresponding dimension of the lower λ/2-antenna structure; and an upper metallization provided on or in contact with a lower surface of the upper substrate; a lower antenna connector coupled to the lower λ/2-antenna structure and running from the lower λ/2-antenna structure through the lower substrate, the upper patch-antenna having a length and a width at least one of which is less than the corresponding dimension of the lower patch-antenna such that the connecting of the lower antenna connector to the lower λ/2-antenna structure is substantially free from being covered by the upper patch-antenna; and 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.
