Kanyanga ye microstripimhando itsva ye microwavekanyangaiyo inoshandisa mitsetse yekufambisa yakadhindwa pa dielectric substrate sechikamu chekupenya kweantenna. Ma microstrip antennas ave achishandiswa zvakanyanya muhurongwa hwemazuva ano hwekutaurirana nekuda kwehukuru hwawo hudiki, huremu hwawo hwakareruka, husina kunyatsojeka, uye nyore kubatanidzwa.
Mashandiro anoita antenna ye microstrip
Nheyo yekushanda kwe microstrip antenna yakavakirwa pakutumirwa uye mwaranzi yemafungu emagetsi. Kazhinji inoumbwa ne radiation patch, dielectric substrate uye ground plate. Radiation patch inodhindwa pamusoro pe dielectric substrate, nepo ground plate iri kune rimwe divi re dielectric substrate.
1. Chigamba chemwaranzi: Chigamba chemwaranzi chikamu chakakosha cheantena ye microstrip. Chigamba chesimbi chakatetepa chinoita basa rekubata nekuburitsa mafungu emagetsi.
2. Dielectric substrate: Dielectric substrate inowanzogadzirwa nezvinhu zvisinganyanyi kurasikirwa, zvine dielectric yakawanda-inogara kwenguva refu, zvakaita sepolytetrafluoroethylene (PTFE) kana zvimwe zvinhu zveceramic. Basa rayo nderekutsigira chigamba chemwaranzi uye kushanda senzira yekupararira kwemafungu emagetsi.
3. Purati yevhu: Purati yevhu isimbi yakakura iri kune rimwe divi repasi pevhu. Inogadzira capacitive coupling ne radiation patch uye inopa kugoverwa kwesimba remagetsi rinodiwa.
Kana chiratidzo che microwave chikaiswa mu microstrip antenna, chinoita wave yakamira pakati pe radiation patch ne ground plate, zvichikonzera radiation yema electromagnetic waves. Kushanda zvakanaka kwe radiation uye pattern ye microstrip antenna zvinogona kugadziriswa nekuchinja chimiro nehukuru hwe patch uye hunhu hwe dielectric substrate.
RFMISOZvinokurudzirwa neMicrostrip Antenna Series:
RM-DAA-4471（4.4-7.5GHz）
RM-MPA1725-9（1.7-2.5GHz）
RM-MA25527-22（25.5-27GHz）
RM-MA424435-22（4.25-4.35GHz）
Musiyano uripo pakati pe microstrip antenna ne patch antenna
Kanyanga yepaneti imhando yekanyanga ye microstrip, asi pane musiyano muchimiro uye musimboti wekushanda pakati pezviviri izvi:
1. Kusiyana kwemaumbirwo:
Antena ye microstrip: inowanzo kuve ne radiation patch, dielectric substrate uye ground plate. Chigamba chacho chakarembera pa dielectric substrate.
Antena yePatch: Chinhu chinopenya cheantena yePatch chakabatana zvakananga ne dielectric substrate, kazhinji chisina chimiro chakarembera pachena.
2. Nzira yekudyisa:
Antena yeMicrostrip: Chikafu chinowanzo batanidzwa nechigamba chinopenya kuburikidza nema probes kana mitsetse ye microstrip.
Kanyanga yekubatanidza: Nzira dzekudya dzakasiyana-siyana, dzinogona kuva kudya kwemucheto, kudya kweslot kana kudya kwecoplanar, nezvimwewo.
3. Kushanda zvakanaka kwemwaranzi:
Antena yeMicrostrip: Sezvo paine mukaha pakati pechigamba chemwaranzi neplate yepasi, panogona kunge paine mukana wekuti mhepo irasike, izvo zvinokanganisa kushanda zvakanaka kwemwaranzi.
Antena yePatch: Chinhu chinopenya cheantena yePatch chakabatana zvakanyanya ne dielectric substrate, iyo inowanzova nemwaranzi yakawanda.
4. Kushanda kwebandwidth:
Antena yeMicrostrip: Bandwidth yakamanikana, uye bandwidth inofanira kuwedzerwa kuburikidza nekugadzirwa kwakagadziridzwa.
Antena yekubatanidza: Kureba kwebandwidth kunogona kuwanikwa nekugadzira zvivakwa zvakasiyana-siyana, zvakaita sekuwedzera radar ribs kana kushandisa zvivakwa zvine layer yakawanda.
5. Zviitiko zvekushandisa:
Antena yeMicrostrip: yakakodzera maapplication ane zvinodiwa zvakasimba pakukwirira kweprofile, zvakaita sekutaurirana nesatellite uye kutaurirana nefoni.
Maantenna ekubatanidza: Nekuda kwekusiyana kwemaumbirwo awo, anogona kushandiswa mumhando dzakasiyana siyana dzemashandisirwo, kusanganisira radar, wireless LANs, uye masystem ekutaurirana emunhu.
Mukupedzisa
Ma antenna e microstrip nema patch antenna ese ari maviri anoshandiswa zvakanyanya muma microwave antenna mumasystem emazuva ano ekutaurirana, uye ane hunhu hwawo uye zvakanakira. Ma antenna e microstrip anobudirira mukushandiswa kwakaoma nzvimbo nekuda kwekusataridzika zvakanaka uye nyore kubatanidzwa. Ma patch antenna, kune rumwe rutivi, anowanzo kuwanikwa mukushandiswa kunoda bandwidth yakakura uye kushanda zvakanaka nekuda kwekushanda kwawo kwakanyanya kwemwaranzi uye dhizaini.
Kuti udzidze zvakawanda nezve antenna, ndapota shanyira:
