摘要:
Implementations and examples of wireless communication systems based on multi-frequency antennas each operating at different frequency bands for wireless communications, including multi-frequency antennas based on metamaterial structures.
摘要:
A wireless device having an antenna structure incorporates a conductive structure to extend an effective length of at least one component of the antenna structure. The enhanced 3-D conductive structure is applicable to a variety of antenna types, including, but not limited to, a CRLH structured antenna.

摘要:
Architectures and implementations of a transceiver system for wireless communications are presented, the system including one or more antennas supporting a single frequency band or multiple frequency bands, a transmit circuit, a receive circuit, and an isolation circuit that is coupled to the one or more antennas and the transmit and receive circuits and provides adequate isolation between the transmit circuit and the receive circuit.
