Broadband High Power Low Insertion Loss Dual Directional Loop Couplers

Makamaka, dual directional loop coupler imapangidwa ndi ma waveguide ozungulira komanso mafunde angapo ophatikizana. Posintha mphamvu yolumikizirana pakati pa kugwirizana .
Waveguide ndi loop waveguide, kufalikira kolowera mphamvu pakati pa ma waveguide osiyanasiyana kumatha kukwaniritsidwa. Chigawo chapakati cha njira yolumikizira loop ndi chozungulira chozungulira cha dielectric, chomwe nthawi zambiri chimapangidwa ndi tubular kapena pepala ngati chipika, chokhala ndi mzere wozungulira wa microstrip mkati mwa chipikacho. Pamene chizindikiro chapamwamba chimalowa mu chipika cha dielectric cha annular kuchokera ku imodzi mwa madoko, chidzasuntha pang'onopang'ono panjira yozungulira m'kanthawi kochepa ndipo pamapeto pake chidzagawidwa ku madoko ena. Panthawi yosinthira, chifukwa cha mawonekedwe a resonance ya chipika cha dielectric ndi njira yokhazikika yozungulira, kusinthika kwa gawo kumasungidwa pafupifupi madigiri 90, kukwaniritsa kugawa mphamvu moyenera.
