Patent attributes
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 λ/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 λ/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.
