Antena ya Microstripndi mtundu watsopano wa microwavemlongotiyomwe imagwiritsa ntchito mizere yoyendetsera magetsi yosindikizidwa pa dielectric substrate ngati chipangizo chowunikira ma antenna. Ma antenna a microstrip akhala akugwiritsidwa ntchito kwambiri m'makina amakono olumikizirana chifukwa cha kukula kwawo kochepa, kulemera kopepuka, mawonekedwe ochepa, komanso kuphatikiza kosavuta.
Momwe antenna ya microstrip imagwirira ntchito
Mfundo yogwirira ntchito ya microstrip antenna imachokera pa kutumiza ndi kuwunikira kwa mafunde amagetsi. Nthawi zambiri imakhala ndi chigamba cha radiation, dielectric substrate ndi ground plate. Chigamba cha radiation chimasindikizidwa pamwamba pa dielectric substrate, pomwe ground plate ili mbali ina ya dielectric substrate.
1. Chigamba cha radiation: Chigamba cha radiation ndi gawo lofunika kwambiri la antenna ya microstrip. Ndi chingwe chopyapyala chachitsulo chomwe chimagwira ndikutulutsa mafunde a electromagnetic.
2. Chitsulo chamagetsi: Chitsulo chamagetsi nthawi zambiri chimapangidwa ndi zinthu zosataya kwambiri, monga polytetrafluoroethylene (PTFE) kapena zinthu zina zadothi. Ntchito yake ndikuthandizira chigamba cha ma radiation ndikugwira ntchito ngati njira yofalitsira mafunde amagetsi.
3. Mbale ya pansi: Mbale ya pansi ndi chitsulo chachikulu chomwe chili mbali ina ya gawo la dielectric. Chimapanga kulumikizana kwa capacitive ndi chigamba cha radiation ndipo chimapereka kufalikira kofunikira kwa malo amagetsi.
Chizindikiro cha microwave chikalowetsedwa mu antenna ya microstrip, chimapanga mafunde oyima pakati pa chigamba cha radiation ndi ground plate, zomwe zimapangitsa kuti mafunde a ma electromagnetic wave ayambe. Kugwiritsa ntchito bwino kwa mafunde ndi kapangidwe ka antenna ya microstrip kumatha kusinthidwa mwa kusintha mawonekedwe ndi kukula kwa chigambacho ndi mawonekedwe a gawo la dielectric.

Kusiyana pakati pa antenna ya microstrip ndi antenna ya patch
Antena ya Patch ndi mtundu wa antena ya microstrip, koma pali kusiyana pakati pa kapangidwe ndi mfundo yogwirira ntchito pakati pa ziwirizi:
1. Kusiyana kwa kapangidwe kake:
Antena ya microstrip: nthawi zambiri imakhala ndi chigamba chowunikira, gawo la dielectric ndi mbale yonyowa. Chigambacho chimapachikidwa pa gawo la dielectric.
Antena Yopachika: Chigawo chowala cha antena yopachika chimalumikizidwa mwachindunji ku gawo la dielectric, nthawi zambiri chopanda kapangidwe koonekeratu koyimitsidwa.
2. Njira yodyetsera:
Antena ya Microstrip: Chakudyacho nthawi zambiri chimalumikizidwa ku chigamba chowala kudzera mu ma probe kapena mizere ya microstrip.
Patch antenna: Njira zodyetsera zimakhala zosiyanasiyana, zomwe zingakhale kudyetsa m'mphepete, kudyetsa malo kapena kudyetsa koplanar, ndi zina zotero.
3. Kugwiritsa ntchito bwino kwa kuwala kwa dzuwa:
Antena ya Microstrip: Popeza pali kusiyana pakati pa chigamba cha radiation ndi ground plate, pakhoza kukhala kutayika kwa kusiyana kwa mpweya, zomwe zimakhudza momwe ma radiation amagwirira ntchito.
Antena ya Patch: Chigawo chowala cha antena ya patch chimagwirizanitsidwa bwino ndi gawo la dielectric, lomwe nthawi zambiri limakhala ndi mphamvu zambiri zowala.
4. Kugwira ntchito kwa Bandwidth:
Antena ya Microstrip: Bandwidth ndi yopapatiza, ndipo bandwidth iyenera kuwonjezeredwa kudzera mu kapangidwe kabwino.
Antena Yopachika: Bandwidth yokulirapo ingapezeke mwa kupanga mapangidwe osiyanasiyana, monga kuwonjezera nthiti za radar kapena kugwiritsa ntchito mapangidwe okhala ndi zigawo zambiri.
5. Nthawi yogwiritsira ntchito:
Antena ya Microstrip: yoyenera kugwiritsa ntchito mapulogalamu omwe ali ndi zofunikira kwambiri pa kutalika kwa mbiri, monga kulumikizana ndi satelayiti ndi kulumikizana ndi mafoni.
Ma antenna olumikizana: Chifukwa cha kusiyanasiyana kwa kapangidwe kake, angagwiritsidwe ntchito m'njira zosiyanasiyana, kuphatikizapo radar, ma LAN opanda zingwe, ndi njira zolumikizirana zaumwini.
Pomaliza
Ma antenna a microstrip ndi ma antenna a patch onse ndi ma antenna a microwave omwe amagwiritsidwa ntchito kwambiri m'njira zamakono zolumikizirana, ndipo ali ndi makhalidwe awoawo komanso zabwino zawo. Ma antenna a microstrip ndi abwino kwambiri pakugwiritsa ntchito malo ochepa chifukwa cha mawonekedwe awo otsika komanso kuphatikiza kosavuta. Koma ma antenna a patch amapezeka kwambiri pakugwiritsa ntchito komwe kumafuna bandwidth yayikulu komanso magwiridwe antchito apamwamba chifukwa cha mphamvu zawo zambiri za radiation komanso kapangidwe kake.
Kuti mudziwe zambiri zokhudza ma antenna, chonde pitani ku:
