Abstract (in Japanese) (See Japanese page) 
(in English) A compact, high-power, and high-directivity surface-emitting terahertz (THz) source based on an active antenna array with integrated patch antenna and resonant-tunneling diode (RTD) is proposed. The radiation power over 10 mW and the DC to RF efficiency of 1 % in a prototype 6×6 array at an oscillation frequency of 0.45 THz are realized. The 3 dB beam width of 13° measured with the 6×6 array indicates the directivity is improved by coherent oscillation based on mutual injection locking.
