STACKED PATCH ANTENNAS
First Claim
1. An antenna assembly operable for receiving signals having different frequencies, the antenna assembly comprising:
- one or more antennas including 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 in communication with the at least one feed point of said one or more antennas for receiving and amplifying signals from the one or more antennas;
first and second band pass filters operable for receiving signals from an output of the low noise amplifier; and
an amplifier operable for receiving a signal from an output of the first band pass filter and for receiving a signal from the output of the second band pass filter, the amplifier operable for generating an output signal.

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.
