Short, dual-driven groundless antennas are provided. One of the antennas includes a tubular outer conductor, a tubular inner conductor, and an electrical connector that electrically connects an opposite end of the outer conductor to the exterior of the inner conductor. The inner conductor is longitudinally disposed within the hollow axial interior of the outer conductor such that an axial gap exists between the radially inner surface of the outer conductor and the radially outer surface of the inner conductor, and the inner conductor runs at least to the opposite end of the outer conductor. Electrical signals are connected to a driven end of both the outer and inner conductors, where these signals supply power to/from the antenna whenever it is used as a transmitter/receiver, and neither of these signals needs to be connected to an electrical ground.

A radio frequency and electromagnetic emission shield employed on wireless personal and portable electronic devices, containing one or more layers of radio frequency (RF) or electromagnetic (EM) screening material, shielding the user from harmful RF or EM radiation, or a redirection antenna that receives all RF signals, and redirects those signals away from the user. The RF emission shield may be contained within a plurality of outer layers, providing a secure fit to a wireless electronic device and an outer layer providing an easy grip for the user.

One example system includes a biosensor applicator having a housing defining a cavity configured to receive and physically couple to a biosensor device, and to apply the biosensor device to a wearer; an applicator coil antenna oriented around a first axis; and a biosensor device including a biosensor coil antenna; a first wireless transceiver electrically coupled to the biosensor coil antenna; a Bluetooth antenna; and a second wireless transceiver coupled to the Bluetooth antenna; wherein the biosensor device is physically coupled to the biosensor applicator and positioned at least partially within the cavity; and wherein the applicator coil antenna is configured to wirelessly receive electromagnetic (“EM”) energy from a remote coil antenna and wirelessly provide at least a first portion of the received EM energy to the biosensor coil antenna.

An antenna device suppresses reflection of electromagnetic waves from a human body or other conductors, which causes the electromagnetic waves to be sufficiently emitted in a target direction. The antenna device includes an antenna pattern and a metasurface layer. The metasurface layer is a layer that is layered on the antenna pattern and disposed on the human body side. The metasurface layer includes a first low-loss film and a second low-loss film. A first metasurface is formed on the first low-loss film. A second metasurface is formed on the second low-loss firm.

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.
