| Outline of Final Research Achievements |
300GHz-band plate-laminated double-layer hollow-waveguide corporate-feed 16x16-slot array antennas have been designed for uniform excitation at 350GHz and fabricated by silicon process with tolerance of about several micrometers. Five silicon wafers with 4-inch diameter and 0.2mm thickness are used. 3dB-down gain bandwidth is about 10% (35GHz) in measurements.
Close-proximity communication has been done by facing two antennas to each other. By phase modulation, stable communication not affected by a standing waveguide is confirmed in a range of 0-10mm by theory and measurement.
