The present disclosure is directed to antenna arrangements. In particular, an arrangement can include at least three antennas. A first and second of the antennas can be positioned such that signals they emit cancel each other out at a physical space comprising a third of the antennas. Additionally or alternatively, an arrangement can include at least two antennas. A first of the antennas can comprise at least two signal-emitting portions positioned such that signals they emit cancel each other out at a physical space comprising a second of the antennas.

Multi-antenna Arrangements

Techniques and apparatus based on metamaterial structures provided for antenna and transmission line devices, including single-layer metallization and via-less metamaterial structures.

Single-layer metalization and via-less metamaterial structures

Electronic device

Antenna devices and techniques that provide specific control of the spatial distributions of DC and RF signals at various positions in a wireless apparatus are disclosed. The wireless apparatus includes various device components each having specifications for achieving desired operations in antenna devices.

Antenna devices having frequency-dependent connection to electrical ground

Techniques, apparatus and systems that use composite left and right handed (CRLH) metamaterial structures to combine and divide electromagnetic signals at multiple frequencies. The metamaterial properties permit significant size reduction over a conventional N-way radial power combiner or divider. Dual-band serial power combiners and dividers and single-band and dual-band radial power combiners and dividers are described.

Power combiners and dividers based on composite right and left handed metamaterial structures

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 module and antenna systems

An antenna device includes a substrate having a first surface and a second surface. A first conductive layer is formed on the first surface of the substrate, the first conductive layer having a perimeter defined by one or more shapes having straight or curved edges. The first conductive layer defines a slot and a coupling gap, and also includes a top ground. The coupling gap separates the top ground from a metal plate region. A second conductive layer is formed on the second surface of the substrate, the second conductive layer including a bottom ground. The slot, coupling gap, first conductive layer, and substrate form a composite right and left handed (CRLH) structure.

Multiband composite right and left handed (CRLH) slot antenna

Designs and techniques of Composite Right-Left Handed (CRLH) Metamaterial (MTM) antenna devices, including a CRLH MTM devices that include MTM cells formed on a substrate and a conductive launch stub formed on the substrate to be adjacent to each of the MTM cells and electromagnetically coupled to each of the MTM cells.

Single-feed multi-cell metamaterial antenna devices

A wireless device having a CRLH antenna structure incorporates a meander line at the feed and adds a three dimensional conductive structure to shift a meander mode resonance frequency.

Hybrid metamaterial antenna structures

A computing device includes a capacitively coupled antenna provided in a display portion of the device. An antenna pattern is provided on a backside of a touch screen display. An antenna element is provided in a display housing. The touch screen is attached to the display housing a dielectric adhesive. The dielectric adhesive prevents the antenna pattern from contacting the antenna element such that the antenna pattern is capacitively coupled to the antenna element.

Capacitively coupled computing device antenna

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.

Enhanced metamaterial antenna structures

Techniques, apparatus and systems that use one or more composite left and right handed (CRLH) metamaterial structures in processing and handling electromagnetic wave signals. Antenna, antenna arrays and other RF devices can be formed based on CRLH metamaterial structures. The described CRLH metamaterial structures can be used in wireless communication RF front-end and antenna sub-systems.
