High performance CPW and novel microstrip ring resonators at ∼30 GHz and 40 GHz have been fabricated on Si substrates, using an optimized proton-implantation process. Very good insertion loss and resonator characteristics, close to those from ideal electro-magnetic simulations, were measured. In contrast, the ring resonators on VLSI-standard Si, without implantation, have worse transmission and reflection loss, thus prohibiting applications in RF circuits.
