NOVELTY - The device (400) has a protective housing provided with a wave coupler chamber. A transmission coupler is positioned within the wave coupler chamber. The transmission coupler transmits electromagnetic wave into the wave coupler chamber following receipt of an input signal generated by a set of isolated components or exposed components. A reception coupler is positioned within the wave coupler chamber. The reception coupler transmits a coupler output signal to another set of isolated components or exposed components upon receipt of the electromagnetic wave.    USE - Isolation device e.g. wireless communication device such as ultra-wideband real time locating system (RTLS), global system for mobile communication (GSM) system and universal mobile telecommunication system (UMTS), for use during electrical communication between an isolated component e.g. electronic circuitry such as transceiver, battery, memory, processor and communication circuitry, and an exposed component i.e. antenna, for isolating ignition causing signals and explosions from hazardous or explosive environments.    ADVANTAGE - The device isolates potentially dangerous stimuli from potentially hazardous environments. The device reduces signal losses and improves communication performance. The protective housing isolates isolated components from the explosive environments by reducing or eliminating ignition emissions from electrical pulses/surges, sparks, thermal effects, magnetic fields, electromagnetic radiation and chemical agents. The device prevents damage to the isolated components from the explosive environments. The device allows insulating sleeves to be seated fully within apertures such that the insulating sleeves contact walls of the apertures, thus preventing undesirable shorting of a depicted waveguide.    DETAILED DESCRIPTION - The wave coupler chamber is partially filled by dielectric e.g. epoxy resin and potting compound.
