Outline of Final Research Achievements

Radiation efficiency enhancement of a millimeter-wave on-chip antenna was investigated in this theme. Low radiation efficiency of an on-chip antenna is due to high conductivity of the silicon substrate. High precision electromagnetic simulation model was investigated at first. Two methods, 1) use of well protection layer, 2) He-3 ion beam irradiation, were performed to improve radiation efficiency. Radiation efficiency of 40 % was obtained by He-3 ion irradiation.
