概要	In this paper, a 60GHz CMOS on-chip dipole antenna with helium-3 ion irradiated silicon substrate is designed using knowledge of electromagnetic simulation modeling. Rectangular region with 500um×1000um around the dipole is irradiated by helium-3 ion and conductivity is reduced to 0.01S/m (1kΩ-cm). The　width of dipole section is wide for broad bandwidth and reduction of conductor loss. There are a taper section and stub for impedance matching. A backing metal reduces back radiation. At 62GHz, the calculated reflection, radiation efficiency and gain are -15dB, 48% and 2.7dBi, respectively. 副筆
