Antenna radiation pattern control using EBG/AMC surfaces for street furniture applications

This paper describes initial research into exploiting EBG structures to reduce the dimensional profile of street furniture antennas. One antenna of interest is normally mounted on the walls of buildings and is designed to radiate energy as close to endfire as possible. This enables efficient communication with mobile phones along the street, rather than illuminating buildings located opposite the antenna. The paper focuses on detailing the theoretical approach of how one would use an EBG surface to direct antenna energy away from boresight. This approach is validated via simulations of a dipole spaced 0.25lambda away from a square patch EBG, reducing the profile of the structure by 36.5%. The frequency range of interest for this paper is 880-960MHz.
