NRD GUIDE-MICROSTRIP LINE CONVERTER CAPABLE OF MATCHING BETWEEN NRD GUIDE AND MICROSTRIP LINE

摘要

PURPOSE: An NRD(Non-Radioactive-dielectric Waveguide) guide-microstrip line converter is provided to optimize the impedance matching between an NRD guide and a microstrip line by optimizing a signal conversion process among the NRD guide, a feeder, and a strip line. CONSTITUTION: An NRD guide dielectric line(13) is coupled to a mode splasher(14). The mode splasher is coupled to a plurality of dielectric blocks. A plurality of feeders(16a,16b) are coupled to ends of the dielectric blocks according to the predetermined coupling depth. The feeders are coupled to a microstrip line. The microstrip line is formed on a dielectric substrate(18) adhered vertically to a sidewall of the metal block(17).
