Microfabricated Ion Trap Chip With An Integrated Microwave Antenna

Description

An ion trap chip, which may be used for quantum information processing and the like, includes an integrated microwave antenna.  The antenna is formed as a radiator connected by one of its ends to the center trace of a microwave transmission line and connected by its other end to a current return path through a ground trace of the microwave transmission line.  The radiator includes several parallel, coplanar radiator traces connected in series.  The radiator traces are connected such that they all carry electric current in the same direction, so that collectively, they simulate a single, unidirectionally flowing sheet of current.  In embodiments, induced currents in underlying metallization planes are suppressed by parallel slots that extend in a direction perpendicular to the radiator traces.
