UWB RoF bench experimental testing with radio link based on phased antenna array

摘要

The paper describes the results of experimental investigation of the bench, which represents UWB RoF communication system. This bench performs the first prototype of such system and allows it to study from different sides and on different scales. The whole scheme of the bench as well as the detailed description of its elements and characteristics are presented, also the specific issues regarding the connection of the elements are observed. The specific feature of this scheme is application of the phased antenna array as the radiating element of the radio part, which revealed the uncommon questions of matching RoF signal, being transformed from optical into radio domain. The experiment methods are explained in detail. The obtained results are presented and thoroughly analyzed, which revealed that the bench characteristics satisfy the thresholds, set before. Also the experiments on data transmission proved the possibility of successful high-speed data transmission in IR-UWB frequency range on the basis of Radio-over-Fiber technology.
