  • Microstripline waveguide converter
    Publication number: 20050200424
    Abstract: In the inside of the converting portion of a microstripline waveguide converter, on the backside surface of a dielectric substrate, which constitutes, for example, a “stripline antenna,” a strip conductor pattern, which serves as a half-wavelength strip resonator, is disposed, to thereby add a band rejection function to the converter. The size of the converter is thereby reduced.
