We propose and fabricate a 60 GHz-band compact photonic antenna module where a cavity antenna element and a photodiode as well as an optical fiber for RF power feeding are integrated. The operation of the fabricated photonic antenna is demonstrated, which is almost coincident to the simulation result.
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.
A compact-range wireless access system in the 60 GHz-band has been proposed for multi-Gb/s data transfer. Large array antennas adopting in the transmitter operate in their near-field regions, and provide us with a large communication zone and a pure propagation environment. However, intersymbol interference (ISI) may significantly degrade the system performance especially when the receiver is close...
We demonstrate digital signal transmission in RoF system with antenna beam steering capability. Beam steering operation for 40-GHz array-antenna has been experimentally confirmed by quantitatively analyzing the relationship between wavelength tuning range and signal quality.
Beam steering of phased array antenna was achieved by changing the wavelengths of tunable light sources, where RF power was transmitted to the array antenna(through optical fibers with finite chromatic dispersion. A concept of photonic approach to beam steering was first explained and then experimental demonstrations were shown for a 2 GHz array antenna with 4 patch antenna elements and for a 20 GHz...
