Wilkinson power dividerZokonda pa Analogi

Gulu lopanga "trace and load" limagwiritsidwa ntchito mu fayilo ya FDTD yoyeserera Wilkinson_ power_ divider. Magawo akuthupi ndi amagetsi a Wilkinson power divider amamangidwa ndikuyikidwa mu fsp. Chingwe chotumizira ma microstrip chimapangidwa pogwiritsa ntchito mbale yowoneka bwino yamagetsi yamitundu iwiri (PEC) yomwe imayikidwa pagawo laling'ono la 1.59mm yokhala ndi dielectric pafupipafupi ya 2.2. Kutalika kofunikira kwa gawo lililonse la mzere wopatsira kumawerengedwa pogwiritsa ntchito equation. 3.195 ndi 3.197 ku Pozar [1] (onani fayilo ya script ya microstrip.lms mu chitsanzo cha microstrip) ndi 4.9mm (Z0=50 ohms) ndi 2.804 mm (√ 2Z0=70.7 ohms) motsatira. Mzere wotumizira wa kotala wavelength umapangidwa pogwiritsa ntchito ma polygons a 2D opangidwa kukhala mphete. 3.194 mu Pozar [1] ndi λ g/4=55.5 mm. Chotsutsa chimapangidwa pogwiritsa ntchito mbale ya 2D yamakona anayi yomwe imatchula chinthu chokhala ndi R=100 ohms.
 
Madoko amayikidwa pazolowera ndi zotuluka kuti alowetse njira yotumizira ma frequency a 0.5 - 1.5 GHz ndikuwerengera magawo obalaza a zida. Kuti mumve zambiri pazokonda zake, onani tsamba la Ports. Monga tafotokozera pansipa, doko loyambira lidzasinthidwa pamanja kuti liwotche doko limodzi panthawi imodzi.
 
Malo ophimba mauna amaikidwa pa njanji iliyonse kuti athetse kutalika kwake ndi m'lifupi. Kupindika ndi kumakona kwa mayendedwe a nthambi kumafuna kuti kukula kwa gridi munjira za x ndi y kukhala zofanana (dx=dy). Ichi si chopinga pa ma feed ndi ma track omwe amachokera ku coordinate axis. Kope la malo ophimba ma mesh omwe amagwiritsidwa ntchito potsata nthambi amayikidwa kumanja kwa zotuluka kuti musunge mauna ofanana.
 
Mmalire a mayamwidwe a PML akuzungulira dera lonse lofananira, kupatula malire a z-minimum, omwe amasankhidwa ngati malire achitsulo omwe amafananiza njira yoyambira ya mzere wotumizira ma microstrip.
