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

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

This application relates to a multi-functional Composite Right and Left Handed CRLH antenna device. A conductive element of a wireless device is incorporated into the antenna structure for reuse. In one embodiment a peripheral feature, such as a key dome, is incorporated into the antenna device. In this way, the antenna structure includes portions which are multi-functional.

Multi-functional CRLH antenna device

Antennas for wireless communications based on metamaterial (MTM) structures to arrange one or more antenna sections of an MTM antenna away from one or more other antenna sections of the same MTM antenna so that the antenna sections of the MTM antenna are spatially distributed in a non-planar configuration to provide a compact structure adapted to fit to an allocated space or volume of a wireless communication device, such as a portable wireless communication device.
