摘要：
Thin-film slot-array receiving antennas Fed by coplanar waveguide (CPW) were fabricated on fused quartz substrates, and the antenna properties were investigated at 700 GHz. It was confirmed that the transmission efficiency of CPW was 0.83/lambda(m), and the rate of radiated power from a slot antenna was 0.5 at 700 GHz. The fabricated antennas worked as expected from the theory based on the transmission line model, and the two-dimensional 8x3 slot-array antenna fed by CPW increased the power gain by 11 dB over a single-slot antenna. The power gain of the antenna was 13 dBi and the aperture efficiency was 40% when the 700 GHz-submillimeter wave was irradiated through the substrate.
