Abstract: A stacked patch antenna is disclosed that provides desirable performance in a cost effective and space efficient manner. A frame system is used to support a first patch and a second patch and a director plate that can be positioned between the first patch and the second patch. The design of the system allows for the first patch and the second patch to have a lower effective dielectric constant.

Abstract: According to various exemplary embodiments, an antenna assembly generally includes one or more antennas, such as a single multi-frequency antenna, first and second stacked patch antennas, etc. The antenna assembly may be operable for receiving signals having different frequencies (e.g., a frequency associated with a satellite digital audio radio service (SDARS), a frequency associated with a global positioning system (GPS), etc.). The antenna assembly may generally include at least one antenna (e.g., a single multi-frequency antenna, first and second stacked patch antennas, etc.) having at least one feed point and tuned to at least one of a first frequency and a second frequency that is different than the first frequency. A low noise amplifier may be in communication with the at least one feed point for amplifying signals having the first frequency and signals having the second received from a signal output. A single communication link may be used for communicating an output signal of the antenna assembly.

Abstract: In various exemplary embodiments, an antenna assembly includes a first patch antenna and a second patch antenna. The first patch antenna includes a first feed point and is tuned to a first frequency. The second patch antenna includes a second feed point and is tuned to a second frequency. The antenna assembly may also include a transmission line having a first end in communication with the first feed point. A second end of the transmission line may be in communication with the second feed point. One of the first and second ends of the transmission line may provide a signal output for signals that are received by the first and second patch antennas. The antenna assembly may also include a low noise amplifier that receives a signal from the signal output of the transmission line.

Abstract: 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 ?/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 ?/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.

Abstract: 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 ?/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 ?/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 ?/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.
