Abstract

A wideband microstrip to coplanar stripline (CPS) balun has been developed for use in plasma diagnostic radiometric imaging array systems. This balun design includes an impedance transformer and several via holes to realize impedance and field matching. Under TRL measurement, the 2 dB and 3 dB back-to-back insertion loss bandwidth can cover from 2 to 18.45 GHz (1:9.225) and from 2 to 26.5 GHz (1:13.25), respectively.
