Design and development of printed antenna remote units for optically distributed mobile communications

The first demonstration of a printed antenna remote unit (ARU) for opticall y distributed mobile communications compliant with the 1.9-GHz PCN specific ations is presented, The ARU consists of a cavity-backed printed antenna wi th appropriate RF and photonic circuitry. The ARU is low cost, compact, rob ust, and can be easily positioned in typical microcell/picocell sites. A su mmary of the design procedure for the ARU and the measured results are give n. The developed ARU is a key component for the successful deployment of fu ture optically distributed microcellular mobile communications systems.
