Record 1 of 1 Investigation of the use of microwave image line integrated circuits for use in radiometers and other microwave devices in X-band and above NTRS Full-Text:   View Document      [PDF Size: 31.4 MB] Author and Affiliation: Knox, R. M. (IIT Research Inst., Chicago, IL, United States) Toulios, P. P. (IIT Research Inst., Chicago, IL, United States) Onoda, G. Y. (IIT Research Inst., Chicago, IL, United States) Abstract: Program results are described in which the use of a/high permittivity rectangular dielectric image waveguide has been investigated for use in microwave and millimeter wavelength circuits. Launchers from rectangular metal waveguide to image waveguide are described. Theoretical and experimental evaluations of the radiation from curved image waveguides are given. Measurements of attenuation due to conductor and dielectric losses, adhesives, and gaps between the dielectric waveguide and the image plane are included. Various passive components are described and evaluations given. Investigations of various techniques for fabrication of image waveguide circuits using ceramic waveguides are also presented. Program results support the evaluation of the image line approach as an advantageous method for realizing low loss integrated electronic circuits for X-band and above.
