ABSTRACT: This paper describes a low-cost scheme for implementing in-building distributed antenna systems using the photonic-active-integrated-antenna (PhAIA) concept, whereby photonic devices are integrated directly with planar antennas. Deembedded input impedance is measured for an 850-nm vertical-cavity surface-emitting laser and photodiode from 0-10 GHz, and the devices are matched directly to the nonradiating edge of a rectangular-microstrip-patch antenna. Link gain, 1-dB compression point, and spurious-free dynamic range are measured in the links. The fully bidirectional system, which is far from being completely optimized, is then tested over a 300-m laboratory-based multimode fiber link and a 220-m in-building dark-fiber link. Results are shown for throughput and signal-to-noise ratio, and this paper shows that such systems can achieve up to 10-m RF range, at reduced throughput, with no RF amplification.Journal of Lightwave Technology 12/2007; · 2.56 Impact Factor
Conference Proceeding: Near field antennas measurements using photonic antenna[show abstract] [hide abstract]
ABSTRACT: The paper presents a near-field antenna measurements solution using a fiber-optic techniques to improve phase measurements accuracy. Main problem in near-field antenna measurements is phase distortions from changes of cable geometry during the measurements. Measurement solution has been proposed, which allows to illuminate phase errors and consequently to enhance measurement accuracy comparing with conventional technique.Microwave Conference, 2007.
