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.

RF front-end module and antenna systems

This document describes designs and techniques for directly feeding an unbalanced transmission line with a balanced antenna using Composite Right and Left Handed (CRLH) and balun structures. According to various examples, first and second radiating elements, first and second antenna structures, or first and second portions of an antenna structure can provide a left-handed (LH) mode resonance and a right-handed (RH) mode resonance. A feed port can provide an unbalanced signal, and a balun structure can be coupled to the first and second radiating elements, first and second antenna structures, or first and second portions of an antenna structure, to adapt the unbalanced signal from the feed port to a balanced signal for coupling to the first and second radiating elements, first and second antenna structures, or first and second portions of an antenna structure.

Balanced metamaterial antenna device

Techniques and apparatus based on metamaterial structures to achieve tunable operations of an antenna at different antenna frequencies.

Frequency-tunable metamaterial antenna apparatus

Techniques, apparatus and systems for a multiple pole multiple throw (MPMT) RF switch device based on composite left and right handed (CRLH) metamaterial structures.
