Wilkinson simba divideris a power divider circuit. Kana madoko ese achifananidzwa, inogona kuona yekuzviparadzanisa pakati pezviviri zvekubuda ports. Kunyangwe Wilkinson simba divider rinogona kugadzirwa kuti rione chero kupatsanurwa kwesimba (semuenzaniso, ona Pozar [1]), uyu muenzaniso uchadzidza nyaya yekupatsanurwa kwakaenzana (3dB). FDTD ichashandiswa kuwana maparamita ekuparadzira emudziyo.

Boka rekugadzirisa "trace and load" rinoshandiswa muFDTD simulation faira Wilkinson_ power_ divider. Iwo emuviri uye emagetsi paramita eWilkinson simba divider anovakwa uye akaiswa mufsp. Iyo microstrip transmission line inogadzirwa uchishandisa maviri-dimensional akakwana magetsi conductor (PEC) rectangular plate yakaiswa pane 1.59mm gobvu substrate ine hama dielectric constant ye2.2. Upamhi hunodiwa hwechikamu chega chega chekufambisa chinoverengerwa uchishandisa equation. 3.195 uye 3.197 muPozar [1] (ona microstrip.lms script file mu microstrip muenzaniso) ari 4.9mm (Z0=50 ohms) uye 2.804 mm (√ 2Z0=70.7 ohms) zvichiteerana. Iyo kota wavelength yekufambisa tambo inogadzirwa uchishandisa 2D polygons akaumbwa kuita mhete. 3.194 muPozar [1] iri λ g/4=55.5 mm. Chipopori chinogadzirwa uchishandisa 2D rectangular plate inotsanangura chinhu chine R=100 ohms.
Zviteshi zvinoiswa pane yekupinza uye yekuburitsa zviteshi kuti ubaye nzira yekufambisa mutsetse we 0.5 - 1.5 GHz uye kuverenga maparamita ekuparadzira emidziyo. Kuti uwane rumwe ruzivo nezve marongero ayo, ona iyo Ports peji. Sezvinotsanangurwa pazasi, chiteshi chengarava chichashandurwa nemaoko kuti chipise chiteshi chimwe panguva.
Iyo mesh yekuvhara nzvimbo inoiswa pane imwe neimwe track kugadzirisa kureba uye upamhi hwayo. Iko kukotama uye angular zvimiro zvebazi rekutsvaga zvinoda kuti saizi yegridi mu x uye y mafambiro aenzane (dx=dy). Ichi hachisi chinomanikidzira pane chikafu uye chinobuda mateki akaenderana neiyo coordination axis. Kopi yenzvimbo yekuvhara mambure inoshandiswa kutsvagisa bazi inoiswa kurudyi rwekuburitsa trace kuchengetedza symmetrical mesh.
Iyo PML yekunyura yemuganhu mamiriro inotenderedza iyo yese yekufananidza nzvimbo, kunze kweiyo z-minimum muganhu, iyo inotarwa sesimbi yemuganhu mamiriro ekutevedzera pasi pasi peiyo microstrip transmission line.
Wilkinson simba divider Migumisiro uye kuongorora
Nhamba iri pamusoro inoratidza kupindurwa kwemaitiro ekuparadzira maparamita anoshandiswa pakuzviparadzanisa uye kutapurirana simulation uye kugovera kwemagetsi munda pa1GHz. Nhamba idzi dzinogadzirwa ne script mushure mekunge simulation yapera. Izvo zvinofanirwa kucherechedzwa kuti izvi mhedzisiro zvinogona kuwanikwa pane trajectory uchishandisa akakwenenzverwa meshes pane ayo anotsanangurwa musimulation faira.
AnalogiWilkinson simba dividerinonyatso kuenderana pakupinza kwayo (S11=- 40dB, f=1.0GHz) uye yakabuda (S22=- 32dB, f=1GHz) ports, ine yakanaka yekuzviparadzanisa nevamwe (S32=- 43dB, f=1GHz), uye nzvimbo yayo yepakati i1.01GHz, iri mukati me1% yedhizaini inoshanda frequency ye1GHz. Pamusoro pezvo, takaona 3dB yakaenzana simba division (S31 = - 3dB pa f = 1GHz) neshanduko isingasviki gumi muzana muanalog frequency band.
Si Chuan Keenlion Microwave sarudzo yakakura mune narrowband uye Broadband masisitimu, inovhara ma frequency kubva 0.5 kusvika 50 GHz. Iwo akagadzirirwa kubata kubva pagumi kusvika pamakumi matatu ekuisa simba mu50-ohm transmission system. Microstrip kana stripline madhizaini anoshandiswa, uye akakwenenzverwa kuita zvakanaka.
Isu tinogona zvakare kugadzirisa iyo Power Divider zvinoenderana nezvaunoda. Unogona kupinda mupeji rekugadzirisa kuti ripe izvo zvaunoda.
