Kwintsimi yee-eriyali ze-microwave, i-directivity yiparameter esisiseko echaza ukuba i-eriyali igxininisa njani ngokufanelekileyo kumandla kwicala elithile. Ngumlinganiselo wokukwazi kwe-eriyali ukugxila kwimitha yerediyo yerediyo (RF) kwicala elithile xa kuthelekiswa neradiyetha ye-isotropic enqwenelekayo, ekhupha amandla ngokulinganayo kuwo onke amacala. Ukuqonda ukhokelo kubalulekile ku **IMicrowave Antenna Abavelisi**, njengoko ichaphazela uyilo kunye nokusetyenziswa kweentlobo ezahlukeneyo ze-eriyali, kuquka **Ii-Antenna ezicwangcisiweyo**, **Ii-Antenna ezijikelezayo**, kunye nezinto ezifana **Iiadaptha zeWaveguide**.
Ulwalathiso vs. Ukuzuza
I-Directivity ihlala ibhidaniswa kunye nenzuzo, kodwa yimiba eyahlukileyo. Ngelixa i-directivity ilinganisa ingxinano yemitha, inzuzo ithathela ingqalelo ukusebenza kakuhle kwe-eriyali, kubandakanya ilahleko ngenxa yemathiriyeli kunye nokungahambelani kwe-impedance. Umzekelo, i-eriyali ekhokelayo ephezulu efana ne-parabolic reflection igxininisa amandla kumqadi omxinwa, nto leyo eyenza ukuba ilungele unxibelelwano lomgama omde. Nangona kunjalo, inzuzo yayo ingaba ngaphantsi ukuba inkqubo yokutya okanye ** Waveguide Adapter ** izisa ilahleko enkulu.

Ukubaluleka kuYilo lwe-Antenna
Kuba ** Abavelisi be-Antenna yeMicrowave **, ukufezekisa ulwalathiso olufunwayo yinjongo ephambili yoyilo. **Ii-Antenna zePlanar**, ezinjengee-eriyali ze-microstrip patch, zithandwa ngenxa yeprofayili yazo ephantsi kunye nokulula ukudibanisa. Nangona kunjalo, i-directivity yabo ihlala iphakathi ngenxa yeepateni zabo zemitha ebanzi. Ngokwahlukileyo koko, **Ii-Antenna ze-Spiral **, ezaziwa nge-bandwidth yazo ebanzi kunye ne-polarization yesetyhula, zinokufikelela kwi-directivity ephezulu ngokukhulisa ijometri yazo kunye neendlela zokutyisa.

Izicelo kunye noRhwebo
Ii-antenna eziphezulu zokuqondisa zibalulekile kwizicelo ezifana nonxibelelwano lwesathelayithi, iinkqubo ze-radar, kunye ne-point-to-point links. Ngokomzekelo, i-antenna ephezulu ehamba phambili edityaniswe nelahleko ephantsi **I-Adapter ye-Waveguide** inokuphucula kakhulu amandla esignali kunye nokunciphisa ukuphazamiseka. Nangona kunjalo, ukhokelo oluphezulu luhlala luza kunye norhwebo, olufana ne-bandwidth emxinwa kunye nokhuseleko olulinganiselweyo. Kwizicelo ezifuna i-omnidirectional coverage, efana neenethiwekhi eziphathwayo, ii-eriyali ezinolwalathiso olusezantsi zinokufaneleka ngakumbi.

Umlinganiselo woNgqo
I-Directivity idla ngokulinganiswa ngeedecibels (dB) kwaye ibalwe kusetyenziswa ipateni yemitha ye-eriyali. Izixhobo zokulinganisa eziphuculweyo kunye nezicwangciso zokuvavanya, kubandakanywa namagumbi e-anechoic, asetyenziswa yi **Microwave Antenna Manufacturers ** ukujonga ngokuchanekileyo ukuqondisa. Umzekelo, i- **Spiral Antenna** eyenzelwe usetyenziso lwe-broadband inokuvavanywa ngokungqongqo ukuqinisekisa ukuba ulwalathiso lwayo luyahlangabezana neenkcukacha ezifunekayo kulo lonke uluhlu lwamaza.
Ukuqukumbela
I-Directivity yiparameter ebalulekileyo kuyilo lwe-antenna ye-microwave, echaphazela ukusebenza kunye nokufaneleka kwee-eriyali kwizicelo ezithile. Ngelixa ii-eriyali ezinolawulo oluphezulu ezifana nezibonisi zeparabolic kwaye ziphuculwe **Ii-Antenna ze-Spiral** zigqwesa kwizicelo ezigxile kwimitha yemitha, **Ii-Antenna zePlanar** zibonelela ngolungelelwaniso oluthe ngqo kunye nokuguquguquka. Ngokuqonda kunye nokwandisa ulwalathiso, **Abenzi be-Antenna yeMicrowave** banokuvelisa ii-eriyali ezihlangabezana neemfuno ezahlukeneyo zeenkqubo zonxibelelwano lwale mihla. Ingaba idityaniswe ngokuchaneka **I-Adapter yeWaveguide** okanye idityaniswe kuluhlu oluntsonkothileyo, uyilo oluchanekileyo lwe-eriyali luqinisekisa ukusebenza ngokufanelekileyo nangokuthembekileyo.
