Sectoral Waveguide Horn Antenna 3.95-5.85GHz Frequency Range, Pezani 10dBi Type RM-SWHA187-10

A Sectoral Waveguide Horn Antenna ndi mtundu wa antenna othamanga kwambiri a microwave kutengera mawonekedwe a waveguide. Mapangidwe ake oyambira amakhala ndi gawo la mafunde a rectangular lomwe limatseguka ndikutsegula kooneka ngati "nyanga" kumapeto kwina. Malingana ndi ndege ya moto, pali mitundu iwiri ikuluikulu: nyanga ya E-ndege (inawomba mu ndege ya Magetsi) ndi nyanga ya H-ndege (inawomba mu ndege ya Magnetic field).

Mfundo yayikulu yogwiritsira ntchito mlongoti uwu ndikusintha pang'onopang'ono mafunde amagetsi otsekeka kuchokera ku waveguide kupita kumalo aulere kudzera pakutsegula koyaka. Izi zimathandizira kufananitsa kwa impedance ndikuchepetsa kusinkhasinkha. Ubwino wake waukulu ndikuwongolera kwambiri (lobe yopapatiza), kupindula kwakukulu, komanso mawonekedwe osavuta, olimba.

Sectoral waveguide horn antennas amagwiritsidwa ntchito kwambiri pamapulogalamu omwe amafunikira kuwongolera kwamitengo. Nthawi zambiri amagwiritsidwa ntchito ngati nyanga zodyetsa zowunikira zowunikira, m'makina olumikizirana ma microwave, komanso kuyesa ndi kuyeza tinyanga zina ndi zida za RF.
