Low Profile Street Furniture
The increasing number of mobile phones, is leading to network coverage problems, especially in areas where planning permission is hard to obtain for traditional BTS (Base Transceiver Station) sites. This has lead to antennas being housed in existing street furniture such as street signs, lamp-posts and CCTV poles. Such designs help improve network capacity and help in minimising the visual impact of mobile masts and cabinets in towns and city centres.
This research aims to further reduce the visual impact of street furniture antennas by reducing their physical size. The initial focus of this work will be related to reducing the height of bi-directional `shark fin´ antennas using frequency selective surfaces (FSS). A reduction in the physical size of street furniture antennas not only results in improved visual appearance but can also help reduce their weight, cost and wind-loading.
