Antenna module for frequencies in the GHz-range mountable on vehicles features a wide range of functions. Module includes a lower patch-antenna with a lower dielectric substrate. A lower &#x3bb;/2-antenna structure is on the upper surface of the lower substrate for reception of satellite-transmitted frequencies in the GHz range, and a metallization is on the lower surface of the lower substrate. An upper patch-antenna of smaller dimensions and with an upper dielectric substrate is on the lower patch-antenna. An upper &#x3bb;/2-antenna structure for reception of satellite-transmitted frequencies in the GHz-range is on the upper surface of the upper substrate. A metallization is below the upper substrate. A lower antenna connector runs from the lower &#x3bb;/2-antenna structure through the lower substrate. An upper antenna connector separate from the lower antenna connector runs from the upper antenna structure through the upper substrate and the lower patch antenna.

Antenna module

Exemplary embodiments are provided of antenna modules for frequencies in the GHz range and that may be mountable on a motor vehicle. In various exemplary embodiments, an antenna module generally includes upper and low patch-antennas on respective upper and lower substrates. Each patch-antenna includes &#x3bb;/2-antenna structure provided on the upper surface of the respective upper or lower substrate for reception of satellite-transmitted frequencies in the GHz range. A metallization is also provided on or in contact with the lower surfaces of the upper and lower substrates. A lower antenna connector runs from the lower &#x3bb;/2-antenna structure through the lower substrate. An upper antenna connector, separate from the lower antenna connector, runs from the upper antenna structure through the upper substrate and the lower patch-antenna.
