Antenna ea microstripke mofuta o mocha oa microwavelenakanae sebelisang likhoele tsa conductive tse hatisitsoeng holim'a dielectric substrate joalo ka yuniti ea mahlaseli a antenna.Li-antenna tsa Microstrip li 'nile tsa sebelisoa haholo mekhoeng ea kajeno ea puisano ka lebaka la boholo ba tsona bo fokolang, boima bo bobebe, boemo bo tlaase, le ho kopanya habonolo.
Kamoo antenna ea microstrip e sebetsang kateng
Molao-motheo o sebetsang oa antenna ea microstrip o ipapisitse le phetiso le mahlaseli a maqhubu a motlakase.Hangata e na le patch ea radiation, substrate ea dielectric le poleiti ea fatše.Patch ea mahlaseli e hatisoa ka holim'a substrate ea dielectric, ha letlapa la fatše le le ka lehlakoreng le leng la dielectric substrate.
1. Patch ea mahlaseli: Patch ea mahlaseli ke karolo ea bohlokoa ea antenna ea microstrip.Ke tšepe e tšesaane e ikarabellang bakeng sa ho hapa le ho khantša maqhubu a motlakase.
2. Dielectric substrate: Dielectric substrate hangata e entsoe ka thepa e tlaase, e phahameng-dielectric-constant, e kang polytetrafluoroethylene (PTFE) kapa lisebelisoa tse ling tsa ceramic.Mosebetsi oa eona ke ho ts'ehetsa patch ea radiation le ho sebetsa joalo ka setsi sa phatlalatso ea maqhubu a motlakase.
3. Letlapa la fatše: Letlapa la fatše ke lera le leholoanyane la tšepe le fumanehang ka lehlakoreng le leng la substrate ea dielectric.E theha khokahano ea capacitive le patch ea radiation mme e fana ka kabo e hlokahalang ea tšimo ea motlakase.
Ha lets'oao la microwave le fepeloa ka har'a antenna ea microstrip, le etsa leqhubu le emeng lipakeng tsa patch ea radiation le poleiti ea fatše, e hlahisang mahlaseli a maqhubu a motlakase.Ts'ebetso ea radiation le mohlala oa antenna ea microstrip e ka fetoloa ka ho fetola sebopeho le boholo ba patch le litšobotsi tsa substrate ea dielectric.

Phapang lipakeng tsa antenna ea microstrip le patch antenna
Patch antenna ke mofuta oa microstrip antenna, empa ho na le liphapang tsa sebopeho le molao-motheo oa ts'ebetso lipakeng tsa tse peli:
1. Liphapang tsa sebopeho:
Microstrip antenna: hangata e na le patch ea mahlaseli, substrate ea dielectric le poleiti ea fatše.Patch e emisitsoe holim'a substrate ea dielectric.
Patch antenna: Karolo e khanyang ea antenna ea patch e hoketsoe ka kotloloho ho karolo e tlase ea dielectric, hangata ntle le sebopeho se hlakileng se emisitsoeng.
2. Mokhoa oa ho fepa:
Microstrip antenna: Phepelo hangata e hokahana le patch e khanyang ka li-probes kapa li-microstrip lines.
Patch antenna: Mekhoa ea ho fepa e fapane ho feta, e ka ba ho fepa, ho fepa ka slot kapa ho fepa ka coplanar, joalo-joalo.
3. Ho sebetsa hantle ha mahlaseli:
Microstrip antenna: Kaha ho na le lekhalo le itseng pakeng tsa patch ea mahlaseli le poleiti ea fatše, ho ka 'na ha e-ba le tekanyo e itseng ea tahlehelo ea lekhalo la moea, e amang katleho ea mahlaseli.
Patch antenna: Karolo e khanyang ea antenna ea patch e kopantsoe haufi-ufi le karoloana ea dielectric, eo hangata e nang le ts'ebetso e phahameng ea mahlaseli.
4. Ts'ebetso ea Bandwidth:
Microstrip antenna: Bandwidth e batla e le moqotetsane, 'me bandwidth e hloka ho eketsoa ka moralo o ntlafalitsoeng.
Patch antenna: Bophara ba bandwidth bo ka fihlelleha ka ho rala meaho e fapaneng, joalo ka ho eketsa likhopo tsa radar kapa ho sebelisa meaho e nang le mekhahlelo e mengata.
5. Linako tsa kopo:
Microstrip antenna: e loketse lits'ebetso tse nang le litlhokahalo tse tiileng tsa bophahamo ba profil, joalo ka likhokahano tsa sathelaete le likhokahano tsa mehala.
Li-antenna tsa patch: Ka lebaka la ho se tšoane ha meralo, li ka sebelisoa mefuteng e mengata ea lits'ebetso, ho kenyeletsoa radar, li-LAN tse se nang mohala, le litsamaiso tsa puisano tsa motho ka mong.
Ha re phethela
Li-antenna tsa Microstrip le li-antenna tsa patch ka bobeli ke li-antenna tsa microwave tse sebelisoang hangata lits'ebetsong tsa sejoale-joale tsa puisano, 'me li na le litšobotsi le melemo ea tsona.Li-antenna tsa Microstrip li ipabola lits'ebetsong tse thibetsoeng ke sebaka ka lebaka la boemo ba tsona bo tlase le ho kopanngoa habonolo.Li-antenna tsa patch, ka lehlakoreng le leng, li atile haholo lits'ebetsong tse hlokang bandwidth e pharalletseng le ts'ebetso e phahameng ka lebaka la ts'ebetso ea tsona e phahameng ea mahlaseli le sebopeho sa tsona.
