Coupler nigikoresho gikunze gukoreshwa na microwave ya RF ikoreshwa mugukwirakwiza gukwirakwiza ibimenyetso byinjira mubyambu byinshi bisohoka, hamwe nibisohoka biva kuri buri cyambu bifite amplitude hamwe nibice bitandukanye.Ikoreshwa cyane muri sisitemu yitumanaho ridafite insinga, sisitemu ya radar, ibikoresho byo gupima microwave, nibindi bice.
Abashakanye barashobora kugabanwa muburyo bubiri ukurikije imiterere yabyo: microstrip na cavity.Imbere ya microstrip coupler igizwe ahanini numuyoboro uhuza ugizwe n'imirongo ibiri ya microstrip, mugihe imbere yimbere ya cavity igizwe nibice bibiri byicyuma.
