Abstract: An antenna package includes a lid-like structure that fits onto an electrically conductive, metallic box-like structure. The lid-like structure includes an electrically conductive, metallic seal member that is connected to an antenna and defines a primary opening. The antenna includes a dielectric mounted between an inner metallic layer and an outer metallic layer. The connection between the seal member and the antenna is a substantially hermetic, soldered connection between the seal member and the inner metallic layer, such that the inner metallic layer is electrically connected to the seal member. The soldered connection secures the antenna to the seal member such that the inner metallic layer occludes the primary opening. A substantially hermetic, fused connection is provided between the lid-like structure and the box-like structure so that a hermetically sealed chamber is defined within the box-like structure. Electric circuitry is positioned in the chamber and is connected to the antenna.

Abstract: A rescue radio system includes a radio frequency tag, which is carried by and remains with an aircraft, and a rescue radio, which is carried by and remains with an aircrew member. The rescue radio includes an accelerometer that generates an actuation signal in response to the rescue radio being accelerated at a rate that is at least as great as the minimum amount of acceleration that the rescue radio can experience while the rescue radio is being carried by an aircrew member who is ejected from the aircraft. In response to the actuation signal, an interrogator of the rescue radio is activated so that it transmits an interrogatory signal. The radio frequency tag emits a reply signal in response to receiving the interrogatory signal. The interrogator receives the reply signal if the rescue radio is proximate to the radio frequency tag.
