Pankhani ya tinyanga ta microwave, Directivity ndi gawo lofunikira lomwe limatanthawuza momwe mlongoti umayikira mphamvu mbali ina yake. Ndi muyeso wa kuthekera kwa mlongoti kuyika ma radiation pafupipafupi (RF) mbali ina yake poyerekeza ndi radiator ya isotropic yokhazikika, yomwe imawunikira mphamvu mofanana mbali zonse. Kumvetsetsa chiwongolero ndikofunikira kwa **Opanga Antenna a Microwave**, chifukwa imakhudza mapangidwe ndi kugwiritsa ntchito mitundu yosiyanasiyana ya tinyanga, kuphatikiza **Ma Antenna a Planar**, **Mitundu ya Spiral Antennas**, ndi zigawo monga **Ma Adapter a Waveguide**.
Directivity vs. Gain
Kuwongolera nthawi zambiri kumasokonezedwa ndi kupindula, koma ndi malingaliro osiyana. Ngakhale kuwongolera kumayesa kuchuluka kwa ma radiation, kupindula kumaganizira momwe tinyanga zimagwirira ntchito, kuphatikiza kutayika chifukwa cha zida ndi kusagwirizana kwazinthu. Mwachitsanzo, mlongoti wolunjika kwambiri ngati chonyezimira chowonetsera mphamvu imayang'ana mphamvu mu mtengo wopapatiza, zomwe zimapangitsa kuti zikhale zoyenera kulankhulana patali. Komabe, phindu lake likhoza kukhala lotsika ngati dongosolo la chakudya kapena **Waveguide Adapter** liyambitsa kutayika kwakukulu.

Kufunika Pakupanga kwa Antenna
Kwa **Microwave Antenna Manufacturers**, kukwaniritsa chiwongolero chomwe mukufuna ndicho cholinga chachikulu chopangira. **Planar Antennas**, monga tinyanga tating'onoting'ono tating'onoting'ono, timatchuka chifukwa cha kutsika kwawo komanso kuphatikiza kosavuta. Komabe, kuwongolera kwawo kumakhala kocheperako chifukwa cha mawonekedwe awo ochulukirapo. Mosiyana ndi izi, ** Spiral Antennas **, yomwe imadziwika ndi bandwidth yawo yotakata komanso kuzungulira kozungulira, imatha kuwongolera kwambiri pakuwongolera ma geometry awo ndi njira zodyetsera.

Zofunsira ndi Kusinthanitsa
Ma antenna olunjika kwambiri ndi ofunikira pamapulogalamu monga kulumikizana ndi satelayiti, makina a radar, ndi maulalo olunjika. Mwachitsanzo, mlongoti wolunjika kwambiri wophatikizidwa ndi kutayika pang'ono **Waveguide Adapter** imatha kupititsa patsogolo mphamvu ya siginecha ndikuchepetsa kusokoneza. Komabe, kuwongolera kwakukulu nthawi zambiri kumabwera ndi malonda, monga bandwidth yopapatiza komanso kufalikira kochepa. M'mapulogalamu omwe amafunikira kufalikira konsekonse, monga maukonde am'manja, tinyanga tating'onoting'ono titha kukhala oyenera.

Kuyeza Directivity
Kuwongolera nthawi zambiri kumayesedwa ndi ma decibel (dB) ndikuwerengedwa pogwiritsa ntchito mawonekedwe a radiation ya tinyanga. Zida zoyeserera zapamwamba komanso zoyeserera zoyeserera, kuphatikiza zipinda za anechoic, zimagwiritsidwa ntchito ndi **Microwave Antenna Manufacturers** kuti adziwe zolondola. Mwachitsanzo, **Spiral Antenna** yopangidwa kuti igwiritse ntchito mabroadband imatha kuyesedwa mozama kuti iwonetsetse kuti chiwongolero chake chikukwaniritsa zofunikira pamitundu yonse ya ma frequency.
Mapeto
Directivity ndi gawo lofunikira kwambiri pamapangidwe a tinyanga ta microwave, zomwe zimakhudza magwiridwe antchito komanso kukwanira kwa tinyanga pakugwiritsa ntchito mwapadera. Ngakhale tinyanga zolunjika kwambiri ngati zowunikira komanso zokongoletsedwa **Ma Spiral Antenna** amapambana pama radiation omwe amayang'ana kwambiri, **Planar Antennas** imapereka chiwongolero komanso kusinthasintha. Pomvetsetsa ndi kukhathamiritsa chiwongolero, **Microwave Antenna Manufacturers** amatha kupanga tinyanga zomwe zimakwaniritsa zosowa zosiyanasiyana zamakina amakono olumikizirana opanda zingwe. Kaya zophatikizidwa ndi kulondola kwa **Waveguide Adapter** kapena zophatikizika m'magulu ovuta, kapangidwe koyenera ka mlongoti kumatsimikizira kugwira ntchito koyenera komanso kodalirika.
