We experimentally demonstrated millimeter-wave band beam forming of photonic array antenna composed of compact antenna modules in a Radio-over-Fiber (RoF) system with 1.3 μm light source, variable delay line (VDL), and multi-core fiber. It was confirmed that the antenna beam forming was properly operated by just tuning the optical delay.
We propose a novel 60-GHz compact antenna module integrated with photodiode. The module is actually designed and fabricated, and it is successfully demonstrated that the antenna beams of 1×8 and 2×4 arrayed modules can be remotely controlled by tuning wavelength of 60-GHz RoF signals.
This paper studies the performance of 3.5-Gbit/s quadrature phase shift keying (QPSK) signal radio-over-fiber (RoF) transmission with beam forming of array antennas. An “integrated photonic array- antenna (IPA)” is utilized in this experiment, where uni-travelling carrier photodiodes are fully integrated with 60-GHz-band 4 × 2 array-antenna elements into a single board. The beam forming operation...
A beam steering scheme of photonic array-antennas for 60 GHz RF signals generated by optical two-tone technique is reported. It is experimentally demonstrated that 60 GHz antenna beam can be remotely steered by tuning wavelengths.
We demonstrated beam steering of array-antenna in millimeter-wave band at 39 GHz by WDM Radio over Fiber. The proposed photonic antenna can realize future ultra-broadband and smart antenna systems by a novel photonic approach.
