Waveguide Twist RF RF Microwave Millimeter Umuhengeri

RF waveguide, ijambo risanzwe rikubiyemo uburyo butandukanye bwibyuma bitagira umumaro hamwe nubuso bwo hejuru. Muri byo, iyambere yitwa umuyaga ufunze kubera ko umuyagankuba wa electromagnetiki wohereza ufungiwe rwose imbere mu cyuma. Iyanyuma nayo yitwa open waveguide kuko umuyagankuba wa electromagnetiki uyobora ugarukira kuri perimeteri yimiterere ya waveguide. Imiyoboro nkiyi ya radiyo ifite uruhare runini mu ziko rya microwave, radar, satelite y'itumanaho, hamwe nibikoresho bya radiyo bihuza radiyo, aho bashinzwe guhuza imiyoboro ya microwave hamwe niyakira kuri antene zabo. Waveguide twist nayo yitwa waveguide torsion ihuriweho. Irahindura icyerekezo cya polarisiyasi muguhindura icyerekezo cyimpande nini kandi zifunganye kumpande zombi, kugirango umuyaga wa electromagnetique unyure muriwo, icyerekezo cya polarisiyasi kirahinduka, ariko icyerekezo cyo gukwirakwiza ntigihinduka.
Iyo uhuza milimetero yumurongo wumurongo, niba impande nini kandi zifunganye zimpande zombi zinyuranye, ni ngombwa gushyiramo iyi mpinduramatwara ihindagurika nkinzibacyuho. Uburebure bwa waveguide twist bugomba kuba integer nyinshi ya λ g / 2, kandi uburebure bugufi ntibugomba kuba munsi ya 2 λ g (aho λ g nuburebure bwumurongo wa waveguide).
