Coplanar Lines : Application to Broadband Microwave Integrated Circuits

Abstract

The paper begins with a brief review of some of the shortcomings of the microwave microcircuit techniques most widely used in research and industry (e.g. microstrip, suspended stripline, and slot line). This is followed by a discussion of the advantages likely to be associated with the utilization of the coplanar line technique. The propagation characteristics are then determined using a digital calculation program. Finally, several applications are discussed involving or impedance matchers capable of operating at Ku-band frequencies.
