In today’s world of communication, the wireless access network is a rapidly growing technology. As upcoming generations of wireless communication require more number of diminished cells than that used in the current generation, photonic antenna and RoF are being considered as the key technologies for such futuristic applications. RoF technology has the special feature of combining the characteristics of both a free space radio and an optical fiber link. Due to the larger bandwidth, competitive cost and low propagation loss, optical fiber has become the best option for the backhaul. In this work, architecture (architecture in an uncountable noun, so no article is required) has been proposed for analyzing the structure of a 2.4 GHz photonic antenna for RoF system. The architecture has a significant importance in meeting the demand for higher bandwidth. The system provides an optimum performance at a data rate of 2.5 Gbps over a fiber length of 50 km, employing 16-QAM modulation scheme. The quality of the received signal has also been analyzed by varying fiber length and transmitted power for different types of fibers.
