Multimode horn antenna
M'mapulogalamu ambiri, tinyanga ta nyanga timafunika kuti tipereke mawonekedwe ofananira mu ndege zonse, zochitika zapakati pagawo mu ndege za $ E $ ndi $ H $, ndi kuponderezana kwa lobe.
Maonekedwe a nyanga yosangalatsa yamitundu yambiri amatha kupititsa patsogolo kufananiza kwamitengo ya ndege iliyonse ndikuchepetsa mulingo wam'mbali.Chimodzi mwazinthu zodziwika bwino za nyanga za multimode ndi mlongoti wamitundu iwiri.
Dual Mode Conical Horn Antenna
Nyanga yapawiri-mode ya cone imapangitsa kuti ndege ya $ E $ iwonetsetse mawonekedwe apamwamba a TM11, kotero kuti mawonekedwe ake ali ndi mawonekedwe a axially symmetrical equalized mtengo.Chithunzi chomwe chili pansipa ndi chojambula chojambula cha kugawa kwamagetsi amagetsi amtundu waukulu wa TE11 mode ndi mawonekedwe apamwamba a TM11 mumayendedwe ozungulira ozungulira ndi kugawa kwake kotsegula komweko.
Kapangidwe ka nyanga yamitundu iwiri si yapadera.Njira zogwiritsiridwa ntchito zodziwika bwino zimaphatikizapo nyanga ya Potter ndi nyanga ya Pickett-Potter.
