Abstract
Provided is a broadband microstrip-waveguide transition apparatus operating in a millimeter waveband. The millimeter-wave band broadband microstrip-waveguide transition apparatus includes a slot for transferring an electromagnetic signal propagating along a microstrip line, a main patch positioned between the slot and a waveguide and resonating from the signal transferred from the slot, and a parasitic patch positioned between the main patch and the waveguide and resonating together with the main patch. According to the millimeter-wave band broadband microstrip-waveguide transition apparatus, it is possible to transfer a signal from the microstrip line to the waveguide, and to increase a resonance bandwidth to a broadband level.
