Mode- Transition Adaption Method on the Non-Radiative Microstripline

摘要

The present invention relates to a mode conversion from the non-radiation-up structure of a microstrip line using a metal block, More specifically, the use frequency / 2 strip line of copper foil between the upper and lower grounding metal block with a gap equal to or less than the wavelength of the patterned dielectric substrate is disposed, ; on both ends of the copper strip line active The microstrip line is Te peohyeong metal block is placed on the microstrip line structure for mode conversion as a mutual combination of lower substrate structure for implementing the circuit. ; In the non-radiation microstrip line structure, non-radiation electric field mode in the microstrip line is going up and down around the strip line and the conductive plate, the magnetic field due to the use mode of the MMIC including the typical TEM mode which is a basic structure for rotating the upper and lower conductive plates inside around the conductive plate If the board electronic components are attached to the track strips attached to the rim peohyeong metal block for mode conversion in the conversion of a TEM mode should occur naturally in the Quasi-TEM. ; So defamatory using Te peohyeong metal block four microstrip line and there is an active element can naturally lead to a mode conversion from the strip line is attached, such as MMIC, microwave and millimeter wave band to be used in the frequency up to the optimum transmission line to produce an RF active circuitry and passive circuitry will be.
