A band latch mechanism that is configured to connect a wristband to a fitness tracker is provided. The band latch mechanism may be configured to be inserted into a cavity of a housing of the fitness tracker and configured so that any metallic body of the band latch mechanism does not contact metallic surfaces of the cavity in order to prevent an electrical ground from being positioned within a keep-out zone of an antenna of the fitness tracker. A housing with integrated antenna structures is also disclosed.

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

An apparatus including an antenna having an active element and a parasitic element; and at least one support, where the antenna is at least partially on the at least one support, where the at least one support includes a first section coupled to a second different section, where the active element is at least partially on the first section, and where the first section is at least partially formed with a first manufacturing process and a first material. The parasitic element is at least partially on the second section, and the second section is at least partially formed with a second different manufacturing process and a second different material.

Antenna

An apparatus including an antenna; a first antenna carrier forming a first support substrate for a first portion of the antenna; and a different second antenna carrier forming a second support substrate for a second portion of the antenna. The first and second antenna carriers are coupled to each other. The antenna extends across a joint between the first and second antenna carriers.

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.

Non-planar metamaterial antenna structures

Antenna structures and configurations which incorporate alignment keys and support structures which mate Composite Right and Left Handed (CRLH) metamaterial (MTM) structures formed on two or more substrates.

Antenna structures

An antenna device, such as composite right and left handed (CRLH) antenna device, is formed on the substrate, including a ground electrode formed on the substrate. In an example, the antenna device includes a cell patch comprising an enclosed conductive portion formed along an exterior edge of the cell patch, leaving an interior portion of the cell patch to partially expose the substrate. A feed structure is electromagnetically coupled to the cell patch, a via line is coupled to the ground electrode, and a via couples the via line to the cell patch.

Hollow cell CRLH antenna devices

Metamaterial antennas provide spatially varying electromagnetic coupling that enables impedance matching conditions for different operating frequencies of the MTM antennas so that such antennas can operate at different frequencies for wideband applications, including ultra wideband applications.
