A projectile is arranged with antenna, where the projectile is intended for launch in a launch device with a propellant charge in a barrel, where the projectile is arranged with an antenna in the rear edge of the projectile, and where the antenna is arranged behind any of or a combination of: i. a protective cap which protects the antenna during the ejection phase in the barrel and which is removed when the projectile has left the barrel; and ii. a protection in the form of a molding compound arranged to protect the antenna.

The invention is a modular buoyant cable antenna that is towed on the surface of a body of water by a submerged underwater vehicle to allow communication coverage in an omnidirectional pattern that is also compatible with existing buoyant cable antenna deployment and retrieval systems. The antenna of the present invention comprises a floating cable having four identical antenna elements that are arranged in a cross configuration. The antenna uses the sea surface as a ground plane providing good antenna gain levels. The antenna is designed with an integrated impedance matching network to maximize radiation efficiency.

A provided wireless wallbox dimmer may accommodate a plurality of button configurations. The dimmer may be configured to contain a variable number of controllably conductive devices. The dimmer may include a yoke that defines a first plane and an antenna that defines a second plane that is substantially parallel to and spaced apart from the first plane. The yoke may have a flange that is oriented angularly offset relative to the first plane and provides a plurality of mounting locations for controllably conductive devices. The antenna may provide the dimmer with a first wireless transmission range. The dimmer may include a faceplate that cooperates with the antenna to provide the dimmer with a second wireless transmission range that is broader than the first wireless transmission range. The dimmer may include a button assembly that is supported independently of the yoke.

A trailing wire antenna connector comprising: a spool; a trailing line and a conductive socket. The trailing line is configured to be wound around the spool and consists of a non-conductive line segment joined to a conductive wire segment via a conductive plug. The non-conductive line segment is connected to the spool. The conductive socket is configured to be mounted to a fuselage so as to be electrically insulated from the fuselage and electrically connected to a feed line of an RF receiver. The conductive socket has an opening through which the conductive wire segment may pass but that is too small for the conductive plug to pass such that when the conductive plug comes into contact with the conductive socket the conductive wire segment is electrically connected to the feed line.

Aspect of the present disclosure are directed to methods and apparatus producing enhanced radiation characteristics, e.g., wideband behavior, in or for antennas and related components by providing concentric sleeves, with air or dielectric material as a spacer, where the sleeves include one or more conductive layers, at least a portion of which includes fractal resonators closely spaced, in terms of wavelength. A further aspect of the present disclosure is directed to surfaces that include dual-use or multiple-use apertures. Such aperture engine surfaces can include a top (or first) layer of antenna arrays, a middle (or second) layer of a metal-fractal backplane player, and a third (or bottom) layer for solar cell or solar oriented power collection.
