Kodi Antena ya Microstrip ndi chiyani? Kapangidwe, Mfundo Yogwirira Ntchito ndi Kugwiritsa Ntchito

Chidule cha Zamalonda ndi Ukadaulo

Antena ya microstrip ndi antena yozungulira yopangidwa ndi chigamba choyatsira magetsi, gawo la dielectric, ndi gawo la pansi. Chigambacho nthawi zambiri chimasindikizidwa mbali imodzi ya gawo la pansi, pomwe gawo la pansi limayikidwa mbali inayo. Kapangidwe kameneka kamapangitsa antena kukhala yopyapyala, yopepuka, komanso yoyenera kuyikidwa pamapulatifomu athyathyathya kapena opindika pang'ono.

Mu ukadaulo wa RF wothandiza, ma microstrip antenna amaonedwa kuti ndi ofunika chifukwa amatha kuphatikizidwa ndi ma microwave circuits, phased arrays, radomes, ndi compact system housings. Makhalidwe awo a radiation amatha kusinthidwa kudzera mu patch geometry, substrate material, feeding method, array array, ndi mechanical layout.

Kapangidwe Koyambira ka Antena ya Microstrip

Antena wamba wa microstrip uli ndi zigawo zitatu zazikulu. Chigamba chachitsulo chapamwamba chimagwira ntchito ngati chinthu chowunikira. Chophimba cha dielectric chimathandizira chigambacho ndipo chimakhudza bandwidth, magwiridwe antchito, ndi kukula kwake. Gawo la pansi limathandiza kufotokozera momwe kuwala kumayendera ndikulekanitsa antena ndi malo oikira.

Chigamba chowala	Kawirikawiri imakhala yozungulira, yozungulira, kapena yopangidwa mwamakonda kuti igwirizane ndi ma frequency ndi polarization.
Chitsulo chamagetsi	Yosankhidwa malinga ndi kutayika kwa RF, nthawi zonse ya dielectric, makulidwe, bandwidth, ndi zofunikira zachilengedwe.
Ndege yapansi	Amapereka njira yowunikira komanso amathandizira kuti ma radiation agwire bwino ntchito.
Kapangidwe ka chakudya	Ikhoza kugwiritsa ntchito chingwe cha microstrip, coaxial probe, aperture coupling, kapena proxing yapafupi kutengera cholinga chomwe chapangidwira.

Kodi Antena ya Microstrip Imagwira Ntchito Bwanji?

Mphamvu ya RF ikalowetsedwa mu chigamba, mphamvu yamagetsi imakhazikika pakati pa chigamba ndi nthaka. Kuwala kumachitika makamaka pafupi ndi m'mphepete mwa chigamba, komwe mphamvu yamagetsi imafikira m'malo ozungulira.

Mafupipafupi ogwirira ntchito amagwirizana kwambiri ndi kukula kwa chigamba, chokhazikika cha dielectric cha substrate, ndi makulidwe a substrate. Pa chigamba cha rectangle, kutalika kwa resonant nthawi zambiri kumagwirizana ndi pafupifupi theka la kutalika kwa mafunde otsogozedwa mkati mwa substrate.

Mu mapangidwe enieni, miyeso yomaliza iyenera kukonzedwa bwino chifukwa kunyamula kwa dielectric, malo odyetsera, nyumba, zinthu za radome, ndi zomangamanga zachitsulo zapafupi zonse zimatha kukhudza magwiridwe antchito oyesedwa.

Njira Zodziwika Zodyetsera

Kudyetsa Mzere wa Microstrip	Kapangidwe kosindikizidwa kosavuta komanso kuphatikiza kosavuta kwa PCB.	Kuwala kwa mzere wodyetsa ndi kufanana kwake kuyenera kulamulidwa mosamala.
Chakudya cha Coaxial Probe	Kusankha malo osinthira odyetsera kuti mufanane ndi impedance.	Kusonkhana kwa makina ndi kufalikira kwa probe kungakhudze bandwidth.

Ubwino ndi Zofooka

Ubwino Kapangidwe kake ndi kopepuka komanso kotsika. Yoyenera makina ang'onoang'ono a RF ndi ma microwave. Imagwirizana ndi ma circuits ozungulira ndi ma array configurations. Ikhoza kuthandizira kugawanika kwa mzere kapena kozungulira kutengera kapangidwe kake. Kapangidwe ndi mawonekedwe osinthasintha kuti muphatikize mwamakonda.

Zoletsa Bandwidth ikhoza kukhala yopapatiza kuposa mitundu ina ya horn kapena reflector antenna. Kuchita bwino kungakhudzidwe ndi kutayika kwa dielectric ndi kutayika kwa conductor. Magwiridwe antchito amakhudzidwa kwambiri ndi zinthu za substrate, makulidwe, ndi zomangamanga zapafupi. Zinthu zokhudzana ndi kutentha, zachilengedwe, ndi makina ziyenera kuganiziridwa pakugwiritsa ntchito zinthu zovuta.

Mapulogalamu Odziwika

Chifukwa cha mawonekedwe awo olinganizika komanso kusinthasintha kwa kapangidwe kawo, ma antenna a microstrip amagwiritsidwa ntchito m'mapulatifomu ambiri a RF ndi ma microwave komwe malo, kulemera, ndi kuphatikiza ndizofunikira.

Ma Microstrip Array Antennas

Chinthu chimodzi cha microstrip chingagwiritsidwe ntchito chokha, koma makina ambiri a microwave amafunika mphamvu zambiri zowunikira, mawonekedwe, kapena luso lotha kusanthula. Pazochitika izi, zinthu zingapo za patch zitha kuyikidwa muantenna ya microstrip array.

Mwa kuwongolera malo pakati pa zinthu, maukonde odyetsera, kukula kwa malo, ndi kugawa kwa magawo, mainjiniya amatha kukwaniritsa zolinga zosiyanasiyana za beamwidth, sidelobe, gain, ndi polarization. Ma microstrip array antenna nthawi zambiri amaganiziridwa kuti ndi radar, satellite communication, electronic measurement, ndi compact directional RF systems.
