Muchitsauko chakapfuura, takakurukura nezvemapatani emwaranzi. Kuti tinyatsoongorora mwaranzi yeantenna, panoda kutariswa. Mwaranzi yeantena yeisotropic inoita basa iri.
Tsanangudzo
Isotropic mwaranzi inoreva mwaranzi inobva panzvimbo inopararira zvakaenzana kumativi ese, nesimba rakafanana pasinei negwara rekuyera. Kuvandudzwa kwemaitiro emwaranzi yeantenna kunogara kuchiongororwa uchishandisa isotropic mwaranzi sechiratidzo. Kana mwaranzi yakaenzana kumativi ese, inonzi isotropic mwaranzi.
•Point source muenzaniso we isotropic radiator. Zvisinei, isotropic radiation yakadaro haigoneke, nekuti chero antenna inopa simba rayo negwara rakati.
•Mirazvo yeIsotropic yakafanana nemwaranzi yeomnidirectional.
•Kana ichionekwa mu3D, ine patani yakaita sedonati; kana ichionekwa mu2D, ine patani ine nhamba-eight.
Mufananidzo uri pamusoro unoratidza patani yemwaranzi yeradiator inotenderera (kana kuti inotenderera). Mufananidzo 1 unoratidza patani yakaita sedonati mu3D, ukuwo Mufananidzo 2 unoratidza patani yenhamba-sere mu2D.
Kuwana
Radiator ye isotropic ine unity gain, zvichireva kuti gain factor i1 kumativi ese. Kana ikataurwa muma decibels (dB), izvi zvinonzi 0 dB gain (zero loss).
Simba Rakaenzana reIsotropically Radiated (EIRP)
Zvinoenderana netsananguro yakajairwa, huwandu hwesimba rinoburitswa neantena ye isotropic kuti ribudise huwandu hwesimba repamusoro hunoonekwa munzira yekuwedzera kweantena hunonzi Equivalent Isotropically Radiated Power.
Kana simba rinobuda mu antenna rakaiswa parutivi rumwe kana kuti munzira chaiyo, uye mwaranzi iri munzira iyoyo yakaenzana nesimba rinobuda mu antenna re isotropic, mwaranzi iyi inonzi EIRP.
Kuwana
Kunyangwe hazvo radiation yeisotropic iri kungofungidzira chete, inomiririra radiation yakanakisa inogona kuwanikwa neantenna. Antenna yakadaro ine gain ye3 dBi, apo 3 dB inoenderana nefactor ye2, uye "i" inomiririra multiple maererano nemamiriro eisotropic.
Kana mwaranzi yakatarisana mukati meimwe kona, EIRP inowedzera nekuwedzera kwe antenna. Kubudirira kwe antenna kunowanikwa zviri nani nekuisa mwaranzi yayo kune rimwe divi.
Simba Rinoshanda Rinopfuta (ERP)
Kana simba remagetsi rakayerwa richitariswa neantenna yehafu-wave dipole panzvimbo peantenna ye isotropic, rinonzi Effective Radiated Power (ERP).
ERP(dBW)=EIRP(dBW)−2.15 dBi
Kana EIRP ichizivikanwa, ERP inogona kuverengerwa uchishandisa fomura yakapihwa pamusoro.
Kuti udzidze zvakawanda nezve antenna, ndapota shanyira:
