Kwicandelo lee-antenna ze-microwave, i-directivity yiparameter esisiseko echaza indlela i-antenna egxila ngayo amandla kwicala elithile. Yindlela yokulinganisa amandla e-antenna okugxila kwimitha yerediyo (RF) kwicala elithile xa kuthelekiswa ne-radiator ye-isotropic elungiselelweyo, ekhupha amandla ngokulinganayo kuzo zonke iindlela. Ukuqonda i-directivity kubalulekile kwi-**Abavelisi be-Antenna ye-Microwave**, njengoko inefuthe kuyilo kunye nokusetyenziswa kweentlobo ezahlukeneyo ze-antenna, kuquka **Ii-Antennas zePlanar**, **Ii-Antennas ezijikelezayo**, kunye nezinto ezifana **Iiadaptha zeWaveguide**.
Ulwalathiso vs. Ukuzuza
I-Directivity idla ngokubhidaniswa ne-gain, kodwa ziingcamango ezahlukeneyo. Ngelixa i-directivity ilinganisa uxinzelelo lwe-radiation, i-gain ithathela ingqalelo ukusebenza kakuhle kwe-antenna, kubandakanya ukulahleka okubangelwa zizinto kunye nokungafani kwe-impedance. Umzekelo, i-antenna ene-directivity ephezulu efana ne-parabolic reflector igxila amandla kwi-beam emxinwa, okwenza ukuba ilungele unxibelelwano olude. Nangona kunjalo, i-gain yayo inokuba iphantsi ukuba inkqubo yokutya okanye i-**Waveguide Adapter** izisa ilahleko ezinkulu.

Ukubaluleka kuYilo lwe-Antenna
Kubavelisi be-**Microwave Antenna**, ukufezekisa ulwalathiso olufunekayo luyinjongo ephambili yoyilo. **Ii-Antenna zePlanar**, ezifana nee-antenna ze-microstrip patch, zithandwa ngenxa yeprofayili yazo ephantsi kunye nokulula kokudibanisa. Nangona kunjalo, ulwalathiso lwazo ludla ngokuba phakathi ngenxa yeepateni zazo zemitha ebanzi. Ngokwahlukileyo koko, ii-**Ii-Antenna zeSpiral**, ezaziwa nge-bandwidth yazo ebanzi kunye ne-polarization ejikelezayo, zinokufikelela ulwalathiso oluphezulu ngokuphucula i-geometry yazo kunye neendlela zokutyisa.

Izicelo kunye neeNtengiselwano
Ii-antenna eziqondisa phezulu zibalulekile kwizicelo ezifana nonxibelelwano lwesathelayithi, iinkqubo zeradar, kunye neekhonkco ze-point-to-point. Umzekelo, i-antenna eqondisa phezulu edibene ne-**Waveguide Adapter** elahlekileyo kancinci inokuphucula kakhulu amandla esignali kwaye inciphise ukuphazamiseka. Nangona kunjalo, i-directivity ephezulu idla ngokuza nee-trade-offs, ezifana ne-bandwidth encinci kunye nokugubungela okulinganiselweyo. Kwizicelo ezifuna ukugubungela okubanzi, njengeenethiwekhi zeselfowuni, ii-antenna eziqondisa phantsi zinokuba zifanelekile ngakumbi.

Ukulinganisa izikhokelo
Ulawulo oluqondisa izinto ludla ngokulinganiswa ngee-decibels (dB) kwaye lubalwa kusetyenziswa ipateni yemitha ye-antenna. Izixhobo zokulinganisa eziphambili kunye nokuseta kovavanyo, kuquka amagumbi angenamaza, zisetyenziswa ngabavelisi be-**Microwave Antenna** ukumisela ngokuchanekileyo ulwalathiso. Umzekelo, i-**Spiral Antenna** eyenzelwe usetyenziso lwe-broadband inokuvavanywa ngokungqongqo ukuqinisekisa ukuba ulwalathiso lwayo luhlangabezana neemfuno ezifunekayo kulo lonke uluhlu lwefrikhwensi.
Isiphelo
I-Directivity yiparameter ebalulekileyo kuyilo lwe-antenna ye-microwave, echaphazela ukusebenza kunye nokufaneleka kwee-antenna kwizicelo ezithile. Ngelixa ii-antenna ezijolise kakhulu ezifana nee-parabolic reflectors kunye ne-**Spiral Antennas** ezilungiselelweyo zigqwesile kwizicelo zemitha egxile kwi-focused, ii-**Planar Antennas** zibonelela ngokulinganisela kwe-directivity kunye nokuguquguquka. Ngokuqonda nokwenza ngcono i-directivity, **Abenzi be-Microwave Antenna** banokuphuhlisa ii-antenna ezihlangabezana neemfuno ezahlukeneyo zeenkqubo zanamhlanje zonxibelelwano ezingenazingcingo. Nokuba zidibene ne-**Waveguide Adapter echanekileyo** okanye zidibene ne-array eyinkimbinkimbi, uyilo lwe-antenna olufanelekileyo luqinisekisa ukusebenza okusebenzayo nokuthembekileyo.
