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.
