- "In ROF, photonic antenna as intimate integration of optoelectronics, electronics, and planar antenna to produce a highly function module  become increasingly important due to its capability to provide more light-weight and compact package, reduced interconnection losses of connectors and thus producing higher radiated power, wider bandwidth, and potentially lower cost  . However, current photonic antennas             are generally intended for short distance and/or narrowband communications. Therefore, low loss nature which correspond to long distance communication and large available bandwidth which correspond to large information-carrying capacity of optical fiber have not been maximally utilized and the promise of ROF  has not been met yet.

ABSTRACT: A high-gain active photonic antenna is proposed to provide long distance optical and wireless backhaul link. To support service for long wireless distance, RF amplifier and high gain antenna is integrated to the photonic antenna concept. High speed feature is achieved through utilization of simultaneous multi-channel WLAN transmitted through the photonic antenna. Using this notion, the use of four simultaneous channels can potentially provide 216 Mbps at 5 km and 120 Mbps at 7.7 km. Utilization of two simultaneous channels is potentially capable of supporting 108 Mbps at 13.4 km and 72 Mbps at 16.3 km. The speed can be increased if modified WLAN protocol, such as Nstreme2, is employed. These results are significantly higher speed compared to current common practice. This study also remarks that the downlink side is the performance limiter of the photonic antenna system, therefore become the priority to be optimized. Cognitive radio can be adopted to improve the optical link bandwidth utilization and increase aggregate data rate.Telecommunications (ICT), 2010 IEEE 17th International Conference on; 05/2010

ABSTRACT: Article reports on the successful demonstration of the use of the photonic active integrated antenna in wireless LAN (IEEE 802.11a), when microwave communication signals are delivered between the access points and the antenna points in antenna distributing systems via optical fiber. The results of the comparison investigation of the degradation of the dynamic range of the different systems configurations caused by the insertion of the fiber-optic link and photonic active integrated antenna have been presented.Wireless Technology Conference, 2009.
