Abstract:
The described technology provides front-end antenna architecture for wireless communication that manages multiple frequency sub-bands in a manner that results in a low insertion loss rate. Further, the components of the architecture are smaller than typical wireless communication antenna architectures, and therefore the described architecture can be accommodated in a smaller area than typical architectures without a decrease in efficiency. A matching circuit is communicatively connected to each frequency sub-band's respective signal path. When two or more sub-bands are requested for high-speed wireless communication, the matching circuits match the impedance of each sub-band with one-another. Matching the impedance allows two or more sub-bands to be used to wirelessly communicate while maintaining high efficiency. The matching circuits are disabled when only one sub-band is needed for wireless communication.
