Abstract: A composite stack-up for an antenna is described. In one embodiment, the antenna is a flat panel metamaterial antenna. In one embodiment, an antenna assembly comprises an antenna element layer having an upper side and a lower side; a first set of one or more layers forming an upper stack bonded to the upper side of the antenna element layer and being are at least partially transparent to radio frequency (RF) radiation; and a second set of one or more layers forming a lower stack bonded to the lower side of the antenna element layer, where the antenna element layer, upper stack and lower stack are bonded together to form a composite stack.

Abstract: The adhesive extenders can be used to cover and surround the medical electrode assemblies on the skin of a patient. A wearable monitor can be used to obtain electrogram data from the patient via the electrodes.

Abstract: A housing can have two superposed housing members and a joint member connecting lips of the housing members to one another along at least a portion of a periphery. The housing members and the joint member can all be made of an elastomeric material, and thus be flexible, compressible, and have elasticity. An electronic unit within an air-filled cavity between the housing members can be received on a board, itself being received on one of the housing members, and having a press-switch unit covered by the other one of the housing members and forming part of a press-switch system.

Abstract: Antennas such as flat panel, leaky wave antennas with directional coupler feeds and waveguides are disclosed. In one example, an antenna includes a surface having antenna elements, a guided wave transmission line, and a coupling surface. The guided wave transmission line provides a guided feed wave. The coupling surface is between and separates the guided wave transmission line and the surface having antenna elements. The coupling surface controls coupling of the guided feed wave to the antenna elements. The coupling surface can also spatially filter the guided feed wave to provide a more uniform power density for the antenna elements. The guided feed wave can be a high power density electromagnetic wave or a density radially decaying electromagnetic wave.

Abstract: Techniques and mechanisms to provide satellite communication functionality with an antenna assembly. In an embodiment, a communication device includes an antenna panel (comprising one or more holographic antenna elements), a housing and hardware interfaces which facilitate operation of the communication device has a module of the antenna display. A cross-sectional profile of the housing may conform to a polygon other than any rectangle. A configuration of the housing and hardware interfaces may facilitate the formation of an antenna assembly arrangement other than that of any rectilinear array. In another embodiment, communication devices of the antenna assembly each conform to a triangle or a hexagon.
