NRD GUIDE CIRCUIT ELEMENT AND POSITIONING AND FIXING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To precisely and inexpensively manufacture a circuit element by a comparatively simple constitution. SOLUTION: This circuit element is used in a microwave millimeter wave band, a dielectric line is formed inside the upper and lower conductive plates arranged in parallel at the space of a half-wave length of the free space wavelength of a frequency to be used and an NRD guide circuit in which a signal is transmitted along this dielectric line is composed. At this time, at the center location which is perpendicular to the lower side conductive plate 2 within a dielectric strip 20 composing the dielectric line and is in a width direction, a conductive pin 22 in which the length S1 along a signal transmission direction is 1/4 of the wavelength between dielectric lines of a transmission mode or below is arranged by the pitch P1 which is 1/4 of the wavelength between the dielectric lines of the transmission mode.
