Abstract
A dielectric line converter which includes a dielectric stripline; an upper conductor surface and a lower conductor surface sandwiching the dielectric stripline; the upper and lower conductor surfaces having a first spacing in a first region along the dielectric stripline so as to form a first-kind dielectric line, a second spacing which is substantially zero in a second region so as to form a second-kind dielectric line, and a third spacing which is less than the first spacing in a line conversion region between the first and second regions. Grooves may be formed in the opposing surfaces of the upper and lower conductor surfaces, and the dielectric stripline may be arranged in the grooves. Impedance matching between the first-kind and second-kind dielectric lines is arranged n the line conversion region. The length of the line conversion portion may be set to be an odd multiple of &lgr;/4.
