Antenna imhando yemidziyo yakajairwa, inoshandiswa zvakanyanya muredhiyo, terevhizheni, kutaurirana neredhiyo, radar, kufambisa, magetsi ekupikisa, kuona kure, radio astronomy uye mamwe minda.Antenna chishandiso chinogona kunyatso vheneka mafungu emagetsi kune imwe nzira munzvimbo kana kugamuchira mafungu emagetsi kubva kune imwe nzira munzvimbo.Chero mudziyo unofambisa masaini kuburikidza nemagetsi mafungu emagetsi unofanirwa kutakura antenna.
Isu tinoona muhupenyu hwedu hwemazuva ese kuti kutenderedza kana kutambanudza redhiyo kana terevhizheni antenna, nemaune kana tisingazive, zvinogona kukanganisa kunaka kwechiratidzo.Muchokwadi, inoshandura antenna paramita uye inokanganisa kugamuchirwa kwemafungu emagetsi.Iyo yekufambisa uye yekugamuchira mhedzisiro yeantenna ine hukama zvakanyanya neiyo antenna paramita.Pano isu tinosuma mamwe ekutanga ma parameter eiyo antenna.
1. Kushanda frequency band
Iyo antenna inogara ichishanda mukati meimwe frequency renji (bhendi hupamhi), zvinoenderana nezvinodiwa zveiyo index.Iyo frequency renji inosangana nezvinodiwa zve index ndiyo yekushanda frequency yeantenna.Ma frequency mabhendi anoshandiswa nevashandisi anosiyana neasina waya masisitimu.Naizvozvo, antenna ane ma frequency mabhendi akakodzera anofanirwa kusarudzwa.
2. Gain
Antenna kuwana inoreva simba density reshiyo yechiratidzo inogadzirwa neiyo antenna chaiyo uye yakanakira radiation unit panzvimbo imwechete muchadenga pasi pemamiriro esimba rekupinza rakaenzana.Iko kuwana kwakabatana zvakanyanya neiyo antenna pateni.Iyo yakatetepa iyo huru lobe uye idiki iyo sidelobe, iyo inowedzera kuwana.Antenna kuwana chiyero chekugona kweantenna kupenya mafungu emagetsi mune imwe nzira.Izvo zvinofanirwa kucherechedzwa kuti iyo antenna pachayo haiwedzere simba reiyo inopenya chiratidzo, asi inongoisa simba mune imwe nzira kuburikidza nekubatanidzwa kweantenna vibrators uye kushandura nzira yekudyisa.
3. Bandwidth
Bandwidth ndeimwe yakakosha antenna parameter.Bandwidth inotsanangura huwandu hwemafrequency pamusoro peiyo antenna inogona kunyatsopenya kana kugamuchira simba.Antennas ane diki bandwidth haigone kushandiswa kune Broadband application.
Muhupenyu chaihwo, kuti isangane nezvido zvakasiyana-siyana zvinoshanda, mainjiniya akagadzira akasiyana antenna.Inonyanya kuzivikanwa iyi Antenna refu, inonzi Vertical monopole antenna, kana GP antenna, inowanikwa mumidziyo inobatwa nemaoko.
Iyi ndiyo yakakurumbira Yagi antenna, inogadzirwa neakawanda mayuniti, uye ine dhairekitori yakasimba, iyo yakawanda dhairekitori, iyo yakawedzera kutungamira, inokwirisa kuwana.
Isu tinowanzo kuona rudzi urwu rwedhishi antenna padenga remba.Iyo antenna inotungamira inonyanyo shandiswa kutaurirana kureba.Iyo ine yakatetepa kwazvo danda hupamhi uye yakakwira kwazvo kuwana kukosha, iyo inogona zvakare kunzi yakakwira kuwana inotungamira antenna.
Zvimiro zveantenna zvinoshamisa,
Iwe chete unogona kufungidzira,
Haikwanise kuzviita pasina MHZ-TD
