Antenna assemblies are described herein. In particular, described herein are multi-focal-point antenna devices and compact radio frequency (RF) antenna devices. Any of these assemblies may include a primary feed that includes a single patterned emitting surface from which multiple different beams of RF signals are emitted corresponding to different antenna input feeds each communicating with the patterned antenna emitting surface. The antenna assembly is therefore capable of emitting beams in the same direction having different polarizations using a single primary feed.

The disclosed technology provides systems and methods of communication between implanted medical devices, e.g., implanted pulse generators, and handheld consumer devices, e.g., smartphones, via standard wireless communication protocols, e.g., Bluetooth or Bluetooth Low Energy (BLE) operating in the unlicensed 2.4 GHz frequency band.

Safety radio devices are described herein. One method of constructing a safety radio device includes mounting a radio module on a first layer of a circuit board, fabricating an antenna on a second layer of the circuit board, and constructing a safety radio device by connecting the radio module to the antenna through an aperture formed in the second layer of the circuit board.

A mechanically steered, horizontally polarized, directional antennae for aerial vehicles, such as UAVs. The antenna system can include a planar substrate with a horizontally polarized antenna embedded therein. A rotation member, on one end, can be attached to the planar substrate, and can extend from an external surface of the aerial vehicle. An actuator can be coupled to the rotation member to rotate the rotation member. A communication controller of the aerial vehicle can control the actuator to beam horizontally polarized radiofrequency (RF) waves to a target receiver or receive a wave front from a target transmitter.

In some embodiments, an apparatus for conducting electromagnetic energy may comprise four base linear conductors which are coupled together to form a right rectangle which may be supported by a base. Four slant linear conductors may be coupled to the four base linear conductors. Each slant linear conductor may be coupled to an intersection of two base linear conductors, and each slant linear conductor may also be coupled to the other three slant linear conductors to form a right pyramid shape with an apex. An annular element may be coupled to and encircling the apex formed by the slant linear conductors. A central linear conductor may be coupled to the annular element below the apex, extending perpendicularly towards the base, and coupled to the base. A slant crystal may be coupled to each slant linear conductor and a vertical crystal may be coupled to the central linear conductor.

Provide is an LC resonant antenna including: an inductor layer provided with a coil-shaped inductor; and a capacitor layer provided with a capacitor and laminated on the inductor layer. The capacitor includes a plurality of electrode plates that are aligned with the inductor in a laminating direction of the inductor layer and the capacitor layer and that extend in a surface direction orthogonal to the laminating direction. The inductor is formed to have an axis of a coil center extending in a direction that coincides or substantially coincides with the laminating direction. The plurality of electrode plates each have a passage area that corresponds in the laminating direction to an internal area surrounded by the inductor and allows magnetic flux to pass therethrough.

Disclosed are exemplary embodiments of multiband MIMO vehicular antenna assemblies. In an exemplary embodiment, a multiband MIMO vehicular antenna assembly generally includes a chassis and an outer cover or radome. The outer cover is coupled to the chassis such that an interior enclosure is collectively defined by the outer cover and the chassis. An antenna carrier or inner radome is within the interior enclosure. The antenna carrier has inner and outer surfaces spaced apart from the chassis and the outer cover. One or more antenna elements are along and/or in conformance with the outer surface of the antenna carrier so as to generally follow the contour of a corresponding portion of the antenna carrier.
