115GHz Low-Cost Oscillator-Integrated Reflectarray

This paper presents a low-cost 115 GHz oscillator-integrated folded reflectarray (FRA) for the first time. The oscillator generates a millimeter-wave signal beyond 100 GHz, which is significantly higher than the maximum oscillation frequency ($f_{\max}\approx 70$ GHz) of the employed $0.18\ \mu\mathrm{m}$ CMOS process. Then this oscillator is directly wire-bonded with a wideb...
