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.

Stacked patch antennas

According to various exemplary embodiments, an antenna assembly generally includes a first patch antenna and a second patch antenna. The first patch antenna may include a first feed point and be tuned to a first frequency. The second patch antenna may include a second feed point and be tuned to a second frequency. The antenna assembly may further include a low noise amplifier in communication with the first and second feed points of the respective first and second patch antennas for amplifying signals received by the first and second patch antennas.

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.
