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.
