Iyini i-Microstrip Antenna? Isakhiwo, Isimiso Sokusebenza kanye Nezicelo

Ukubuka Konke Komkhiqizo Nobuchwepheshe

I-antenna ye-microstrip iyi-antenna ehleliwe eyakhiwe yi-patch ekhipha imisebe eqhubayo, i-substrate ye-dielectric, kanye ne-ground plane. I-patch ivame ukuphrintwa ohlangothini olulodwa lwe-substrate, kuyilapho i-ground plane ibekwa ohlangothini oluphambene. Lesi sakhiwo senza i-antenna ibe mncane, ibe lula, futhi ifanele ukufakwa kumapulatifomu ayisicaba noma agobile kancane.

Kubunjiniyela be-RF obusebenzayo, ama-antenna e-microstrip ayaziswa ngoba angahlanganiswa namasekethe e-microwave, ama-array ahlukaniswe ngezigaba, ama-radome, kanye nama-compact system housings. Izici zawo zomsebe zingalungiswa nge-patch geometry, izinto ze-substrate, indlela yokudla, ukuhlelwa kwe-array, kanye nokuhlelwa kwemishini.

Isakhiwo Esiyisisekelo se-Microstrip Antenna

I-antenna ejwayelekile ye-microstrip iqukethe izendlalelo ezintathu eziyinhloko. I-patch yensimbi ephezulu isebenza njengesici esikhipha imisebe. I-substrate ye-dielectric isekela i-patch futhi ithinta i-bandwidth, ukusebenza kahle, kanye nosayizi. Indiza engezansi yephansi isiza ekuchazeni ukuziphatha kwemisebe futhi ihlukanisa i-antenna endaweni yokufaka.

I-patch ekhipha imisebe	Ngokuvamile iwunxande, iyindilinga, noma imise okwezifiso ukuze kube nemvamisa edingekayo kanye nokwahlukana.
I-substrate ye-dielectric	Kukhethwe ngokuya ngokulahlekelwa yi-RF, ukungaguquguquki kwe-dielectric, ukujiya, i-bandwidth, kanye nezidingo zemvelo.
Indiza yasemhlabeni	Inikeza indiza yokubhekisela futhi inegalelo ekusebenzeni okuzinzile kwemisebe.
Isakhiwo sokuphakelayo	Kungase kusetshenziswe umugqa we-microstrip, i-coaxial probe, i-aperture coupling, noma i-proxing ye-proxing kuye ngokuthi i-target iklanywe kanjani.

Isebenza Kanjani I-Antenna ye-Microstrip?

Uma amandla e-RF efakwa epatshini, kusungulwa insimu kagesi phakathi kwepatshi nendawo ephansi. Imisebe ikakhulukazi yenzeka eduze kwemiphetho yepatshi, lapho insimu egoqayo idlulela khona esikhaleni esizungezile.

Imvamisa yokusebenza ihlobene eduze nosayizi we-patch, i-substrate dielectric constant, kanye nobukhulu be-substrate. Kwi-patch engunxande, ubude be-resonant ngokuvamile buhlobene cishe nengxenye yobude be-wavelength obuqondisiwe ngaphakathi kwe-substrate.

Emiklamo yangempela, ubukhulu bokugcina kumele bulungiswe ngoba ukulayisha kwe-dielectric, indawo yokudla, indawo yokuhlala, izinto ze-radome, kanye nezakhiwo zensimbi eziseduze konke kungathinta ukusebenza okulinganisiwe.

Izindlela Zokudla Ezivamile

Indlela Yokondla	Inzuzo Ejwayelekile	Ukucatshangelwa Kobunjiniyela
Okuphakelayo Komugqa We-Microstrip	Isakhiwo esiphrintiwe esilula kanye nokuhlanganiswa kwe-PCB okulula.	Imisebe yomugqa wokudla kanye nokulingana kumele kulawulwe ngokucophelela.
Okuphakelayo Kwe-Coaxial Probe	Ukukhetha iphuzu lokuphakelayo eliguquguqukayo lokufanisa i-impedance.	Ukuhlanganiswa kwemishini kanye nokufakwa kweprobe kungathinta i-bandwidth.
Okuphakelayo Okuhlanganisiwe Kwembobo	Ukuhlukaniswa okuhle phakathi kwenethiwekhi yokuphakelayo kanye nesici esikhipha imisebe.	Isakhiwo esiyinkimbinkimbi kakhulu sezingqimba eziningi kanye nokulawulwa kokukhiqiza okuqinile.
Okuphakelayo Okusondelene	Kungasiza ekuthuthukiseni umkhawulokudonsa kumiklamo ekhethiwe.	Kudinga ukulungiswa okunembile kwezingqimba kanye nokukhetha izinto.

Izinzuzo kanye nokulinganiselwa

Izinzuzo Isakhiwo esiphansi futhi esilula. Ifanele izinhlelo ze-RF eziqinile kanye ne-microwave. Iyahambisana namasekethe e-planar kanye nokucushwa kwe-array. Ingasekela ukuhlukaniswa okuqondile noma okuyisiyingi kuye ngomklamo. Ukuma okuguquguqukayo kanye nokwakheka kokuhlanganiswa okwenziwe ngokwezifiso.

Ukulinganiselwa Ububanzi bomkhawulo bungase bube buncane kunezinye izinhlobo ze-horn noma ze-antenna ezibonisa ukukhanya. Ukusebenza kahle kungathinteka ukulahleka kwe-dielectric kanye nokulahlekelwa yi-conductor. Ukusebenza kuthinta izinto ezingaphansi komhlaba, ukujiya, kanye nezakhiwo eziseduze. Izici zokushisa, ezemvelo, kanye nezokukhanda kufanele zicatshangelwe uma kusetshenziswa izinto ezidinga umzamo omkhulu.

Izicelo Ezijwayelekile

Ngenxa yesimo sazo esihleliwe kanye nokuguquguquka komklamo, ama-antenna e-microstrip asetshenziswa kuzo zonke izinkundla eziningi ze-RF kanye ne-microwave lapho isikhala, isisindo, kanye nokuhlanganiswa kubalulekile khona.

Ama-Antenna e-Microstrip Array

Isici esisodwa se-microstrip singasetshenziswa sodwa, kodwa izinhlelo eziningi ze-microwave zidinga ukukhuphuka okuphezulu, imisebe ebunjiwe, noma ikhono lokuskena. Kulezi zimo, izinto eziningi ze-patch zingahlelwa zibe yi-i-antenna ye-microstrip array.

Ngokulawula isikhala sezinto, inethiwekhi yokondla, ubukhulu, kanye nokusatshalaliswa kwesigaba, onjiniyela bangafinyelela imigomo ehlukene ye-beamwidth, i-sidelobe, i-gain, kanye ne-polarization. Ama-antenna e-Microstrip array avame ukubhekwa njenge-radar, ukuxhumana kwesathelayithi, ukulinganisa nge-elekthronikhi, kanye nezinhlelo ze-RF eziqondile.
