Abstract

The application of closely packed elements to obtain wideband isolation at mobile phone frequency bands, while allowing transparency at the emergency TETRA and Bluetooth bands, is proposed. The intention is to modify the EM architecture of buildings over a very wide frequency range, permitting access at these two very separated bands. In particular, buildings are considered with restricted mobile phone usage such as public libraries, theatres, policing services and secure offices. Experimentally validating the design required scaling the operating frequencies by a factor of ten.
