Mlongoti wa Microstripndi mtundu watsopano wa microwavemlongotiyomwe imagwiritsa ntchito zingwe zosindikizira zomwe zimasindikizidwa pagawo la dielectric ngati gawo lounikira la mlongoti.Antennas a Microstrip akhala akugwiritsidwa ntchito kwambiri m'machitidwe amakono olankhulirana chifukwa cha kukula kwawo kochepa, kulemera kwake, kutsika, komanso kusakanikirana kosavuta.
Momwe microstrip antenna imagwirira ntchito
Mfundo yogwira ntchito ya mlongoti wa microstrip imatengera kufalikira ndi ma radiation a mafunde a electromagnetic.Nthawi zambiri imakhala ndi chigamba cha radiation, gawo lapansi la dielectric ndi mbale yapansi.Chigamba cha radiation chimasindikizidwa pamtunda wa dielectric substrate, pomwe mbale yapansi ili mbali ina ya gawo lapansi la dielectric.
1. Chigamba cha radiation: Chigamba cha radiation ndi gawo lofunikira la mlongoti wa microstrip.Ndi chingwe chowonda chachitsulo chomwe chimagwira komanso kutulutsa mafunde a electromagnetic.
2. Dielectric substrate: Gawo la dielectric nthawi zambiri limapangidwa ndi zinthu zotsika kwambiri, zotsika kwambiri za dielectric, monga polytetrafluoroethylene (PTFE) kapena zinthu zina za ceramic.Ntchito yake ndikuthandizira chigamba cha radiation ndikuchita ngati sing'anga yofalitsa mafunde amagetsi.
3. Chipinda chapansi: Chophimba pansi ndi chitsulo chokulirapo chomwe chili kumbali ina ya dielectric substrate.Imapanga kulumikizana kwa capacitive ndi chigamba cha radiation ndipo imapereka kugawa kofunikira kwamagetsi.
Chizindikiro cha microwave chikadyetsedwa mu mlongoti wa microstrip, imapanga mafunde oyimirira pakati pa chigamba cha radiation ndi pansi, zomwe zimapangitsa kuti mafunde amagetsi azitha kuyatsa.Mphamvu ya radiation ndi mawonekedwe a antenna a microstrip amatha kusinthidwa posintha mawonekedwe ndi kukula kwa chigambacho ndi mawonekedwe a gawo lapansi la dielectric.

Kusiyana pakati pa mlongoti wa microstrip ndi mlongoti wa patch
Chigamba cha mlongoti ndi mtundu wa mlongoti wa microstrip, koma pali kusiyana pakati pa kamangidwe ndi mfundo zogwirira ntchito pakati pa ziwirizi:
1. Kusiyana kwamapangidwe:
Microstrip antenna: nthawi zambiri imakhala ndi chigamba cha radiation, gawo la dielectric ndi mbale yapansi.Chigambacho chimayimitsidwa pagawo la dielectric.
Patch antenna: Chingwe chowunikira cha mlongoti wa patch chimamangiriridwa mwachindunji ku dielectric substrate, nthawi zambiri popanda mawonekedwe oyimitsidwa.
2. Njira yodyetsera:
Mlongoti wa Microstrip: Chakudyacho nthawi zambiri chimalumikizidwa ndi chigamba chowunikira kudzera pa ma probe kapena mizere ya microstrip.
Patch antenna: Njira zodyetsera ndizosiyana kwambiri, zomwe zitha kukhala kudyetsa m'mphepete, kudyetsa kagawo kapena kudyetsa coplanar, ndi zina.
3. Mphamvu ya radiation:
Mlongoti wa Microstrip: Popeza pali kusiyana kwina pakati pa chigamba cha radiation ndi mbale ya pansi, pangakhale kutayika kwa mpweya, komwe kumakhudza mphamvu ya ma radiation.
Patch antenna: Chingwe chowunikira cha chigamba cha antenna chimaphatikizidwa kwambiri ndi gawo lapansi la dielectric, lomwe nthawi zambiri limakhala ndi mphamvu yayikulu ya radiation.
4. Bandwidth performance:
Mlongoti wa Microstrip: Bandiwifi ndi yopapatiza, ndipo bandwidth iyenera kukulitsidwa kudzera mu mapangidwe okonzedwa bwino.
Patch antenna: Bandiwidth yotakata imatha kupezeka popanga zinthu zosiyanasiyana, monga kuwonjezera nthiti za radar kapena kugwiritsa ntchito mitundu ingapo.
5. Nthawi zofunsira:
Mlongoti wa Microstrip: woyenera kugwiritsa ntchito zomwe zili ndi zofunika kwambiri pautali wa mbiri, monga kuyankhulana kwa satellite ndi mafoni.
Patch antennas: Chifukwa cha kusiyanasiyana kwawo, amatha kugwiritsidwa ntchito pazinthu zambiri, kuphatikiza ma radar, ma LAN opanda zingwe, ndi njira zoyankhulirana zamunthu.
Pomaliza
Minyanga ya Microstrip ndi tinyanga tating'onoting'ono ndi tinyanga ta microwave zomwe zimagwiritsidwa ntchito kwambiri pamakina amakono olankhulirana, ndipo ali ndi mawonekedwe awoawo komanso zabwino zake.Ma antennas a Microstrip amapambana muzochita zolephereka chifukwa cha kutsika kwawo komanso kuphatikiza kosavuta.Komano, tinyanga ta zigamba, ndizofala kwambiri pamapulogalamu omwe amafunikira bandwidth yotakata komanso kuchita bwino kwambiri chifukwa chakuchita bwino kwa ma radiation komanso mawonekedwe ake.
