Technologies for RF to Millimeter Wave Circuits

In this paper, different technologies currently available for building RF to millimeter wave circuits are briefly described. These include: microstrip, suspended substrate line, dielectric integrated guide and microelectromechanical system technologies. Several major projects using the aforementioned technologies have been successfully completed at the Centre for Applied Research in Electronics (CARE). Novel techniques developed to analyze and build complex microwave and millimeter wave circuits using microstrip, suspended stripline, non-radiative dielectric guides and micromachined transmission lines are presented
