RFID Antennas a lam hpe kade daram chye ai

Internet of Things hpe computer hte Internet ngut ai hpang shiga hpaga lam a masum ngu na wave hku nna mu mada ma ai. Shi hpe chye na ai lam hta, matut mahkai lam, sensor, RFID, hte positioning zawn re ai high{1}} hpaji masa law law hpe jawm galaw ra ai. RFID, Internet, matut mahkai lam hte kaga hpaji masa ni hpe kahkyin gumdin ai gaw, mungkan ting na arung arai ni hpe hkan tam ai lam hte shiga ni hpe garan gachyan ai lam hpe chye na la lu na re. Dai majaw, Internet of Things hpe chye na na matu ahkyak ai npawt nhpang langai hku sawn la nna, tsaban 21 hta ahkyak ai hpaji masa shi kaw na langai hku nna masat da ai.

Wireless matut mahkai lam hta, antenna gaw n mai malap ai daw langai mi re. RFID gaw radio wave ni hpe jai lang nna shiga ni hpe htawn tsun dan ai, radio wave ni hpe shapraw ai hte hkap la ai lam hpe antenna hku nna ngut kre hkra galaw ra ai. Electronic tag gaw laika hti ai wa/ka ai antenna a bungli galaw ai shara de shang wa ai shaloi, dai electronic tag antenna gaw n-gun hpe lu la na matu ra ai induced current hpe shapraw ya ai. RFID masa a matu, antenna gaw ahkyak ai daw langai mi rai nga ai, dai gaw system a bungli galaw ai lam hte grai ni htep ai.

Ga shadawn, warehouse management project langai hta, RFID antenna ni a manu gaw, yawng a manu hta na 1% hta n-pu na re. Raitim, manu jahpu hpe n-gun n rawng ai hku (sh) kaga lam ni a majaw shayawm lu na matu, n kaja ai hku galaw ai RFID antenna hpe lata ai rai yang, n-gun n rawng ai laika hti ai, laika n lu hti ai, cross{2}} reading zawn re ai manghkang ni, hti ai lam hta hkrat sum ai lam ni gaw RFID antenna a layout galaw ai aten hta loi loi hte byin wa na re. Ndai mabyin hta, manu hpe shayawm kau na sha n-ga, kalang lang jat wa na re. Dai majaw, RFID system ni hpe jai lang ai shaloi RFID antenna ni hpe myit maju jung ra ai.

RFID antenna amyu ni gaw hpa ni rai kun?

RFID masa a antenna ni hpe n-gun n rawng ai hku garan nna, electronic tag antenna hte laika hti ai ni a antenna ngu ai lahkawng hku garan mai ai. Ndai antenna amyu lahkawng hpe hkrang shapraw ai lam hte maren, shara shagu na antenna ni hte lam madun ai antenna ni hku nna garan mai ai, hkrang n bung ai hte maren linear antenna ni hku nna mung garan mai ai. Bai nna planar antenna ni. RFID hti ai/ka ai antenna ni hta broadband hte grup yin garan ginhka ai atsam ni nga ra ai. N-gun n law ai hte n-gun kaba ai band ni hta, electronic tags ni hte laika hti ai ni gaw, madung hku nna coil antenna ni hpe lang nna, magri wire ni hpe madung lang ai. Raitim, n-gun kaba ai frequency grai law ai majaw, antenna a turns ni gaw n law ai frequency hta grau n law na re, dai gaw RFID antenna kaba ai hpe galaw shapraw na matu loi ai hte manu mung yawm mat ai. UHF frequency band hta, grau nna etching galaw ai lam ni hpe jai lang ai, dai hta copper etching antenna hte aluminum etching antenna ni lawm ai, dai hta n-ga, galaw sa wa ai lam ni gaw grai kungkyang ai. Microwave frequency band hta, antenna ni a hkrang ni gaw grau nna amyu myu nga ai, dai hta, symmetrical dippele antenna, microstrip antenna, array antenna, broadband antenna ni, hte kaga ni lawm ai.

frequency band ni hte n bung ai application field ni hta electronic tag antenna a hkrang hpe ra sharawng ai lam n bung ai. Madung hku nna, antenna design gaw lawu na yaw shada lam ni hpe hkan sa chye ai:

(1) Antenna volume hpe mai byin ai daram shayawm kau na;

(2) Antenna gaw chip hpe mai byin ai signal kaba dik htum hpe jaw ya ai;

(3) Antenna coverage a directivity gaw mai byin ai daram kaba ra ai;

(4) Antenna a polarization gaw laika hti ai wa a san jep ai signal hte bung ai;

(5) Antenna manu gaw mai byin ai daram yawm ai hte kaga lam ni hpe galaw ai.

RFID antenna galaw shapraw ai lam a madung lam masum hpe

RFID galaw ai lam a masa amyu myu hta ra kadawn ai lam amyu myu hpe hkan sa na matu, RFID antenna galaw shapraw ai lam amyu myu pru wa sai. Ya aten hta, grau nna lang ai RFID antenna galaw shapraw ai ladat ni hta, madung hku nna, coil htinggrang ladat, etching ladat hte laika ka ai ladat ni lawm ai.

(1) Coil turning ladat

RFID tag antenna hpe galaw na matu coil winding ladat hpe lang ai shaloi, tag coil gaw hkala nba hte n-gun rawng ai arung arai langai a ntsa e jung da ra ai. Antenna coil hpe turn law law lu na matu ra ai. Dai coil gaw grup yin shingnip (sh) rectangular ring. . Ndai ladat hpe RFID tags ni a matu 125 kaw nna 134KHz du hkra frequency frequency hte madung lang mai ai. Ndai processing ladat hpe antenna ni hpe galaw na matu jai lang ai a n-gun kya ai lam ni gaw dan dawng nga ai, dai hpe madung hku nna manu kaba ai, galaw shapraw ai atsam n law ai, galaw shapraw ai arung arai ni a n-gun n law ai hku nna shingdaw mai ai.

(2) Etching ladat

Etching ladat gaw, antenna galaw na matu, magri (sh) aluminum hpe lang chye ai. Ndai ladat gaw, n-gun rawng ai circuit board ni a etching process hte bung ai. Etching ladat hpe 13.56MHz hte UHF bandwidth hte electronic tags ni hpe mass galaw shapraw ai hta lang mai ai. Dai hta n-gun ja ai circuit, n-gun n law ai, nbung laru hpe ninghkap lu ai, n-gun n rawng ai masa ni a akyu ni nga ai. Raitim, ndai ladat a n-gun kya ai lam ni mung dan dawng nga ai, ga shadawn, n-gun n rawng ai galaw shapraw ai ladat ni hte n-gun n law ai.

(3) Printing ladat

Dai majaw, n-gun n rawng ai antenna gaw, antenna circuit hpe hpaw na matu, insulating substrate (sh) film ntsa kaw hkrak hkrak dip shapraw ai circuit langai mi re. Madung dip shapraw ai ladat gaw, screen printing hpe lang nna, laika dip ai, flexographic printing, gravure printing hte kaga galaw shapraw ai ladat ni hpe jai lang ai kaw nna, jat wa ai. Laika dip ai ladat gaw 13.56MHz hte RFID UHF electronic tags ni hpe masha law law galaw na matu htuk manu ai. Dai gaw lawan ai hku galaw shapraw ai lawan ai lam hte laklai ai, raitim, conductive ink hku nna byin pru wa ai circuit kaba a majaw, shi a jai lang ai lam gaw madang langai ngai hta sha madung tawn ai. Laika shapraw da ai antenna hpaji masa rawt jat wa ai majaw, RFID tags ni a manu hpe atsawm sha shayawm kau lu ai majaw, RFID application ni hpe masha law law chye na hkra galaw lu wa sai.

RFID antenna ni a htawm hpang na rawt jat lam masa

(1) Kaji ai hpe shayawm kau ai

Hpaji rawng ai ra kadawn ai lam hte galaw sa wa ai hpaji masa ni hpe gyin shalat wa ai hte maren, RFID antenna ni a galu kaba ai lam gaw, kaji kajaw hpe n-gun shayawm ai lam de naw rawt jat wa nga ai. Lawu low{1}} n-gun hte n-gun kaba ai- a electronic tags ni hta, antenna a kaba ai gaw chip hta grau kaba ai. Dai majaw, tag a kaba ai hpe antenna kaba ai hku nna pat shingdang chye ai. Gat lawk ra kadawn ai lam a ningmu hku yu yang, RFID tags ni hpe kaji kajaw sha galaw ai lam gaw, grau law ai application masa ni de shang wa na matu mung mai byin ai.

(2) Missa galaw ai lam

Htunghking ladat hte shingdaw yu yang, conductive ink printed antenna gaw manu n law ai hte grau kaja ai hku galaw shapraw ai lam nga ai, dai hpe madung hku nna conductive ink hta lang ai arung arai ni a manu n law ai hta mu lu ai, screen printing galaw ai hta lang ai printing jak ni mung etching jak ni hta manu n hkrat ai. Dai hta n-ga, ndai printing galaw ai lam gaw asan sha rai nna, lawan ai hku galaw lu ai, process flow yawng gaw loi loi sha rai nga ai, dai gaw mass galaw na matu grau htap htuk ai.

(3) Hpun kawa ni hte grup yin hpe makawp maga ai lam galaw ai

Dai hta n-ga, etching galaw ai hta chemical n-gun shayawm ai lam gaw, n kaja ai lam ni hpe shabyin ya na re, dai gaw grup yin hpe awu asin byin shangun na matu loi ai. Dai hte nhtan shai ai hku nna, conductive ink printing hpaji gaw grup yin hpe grau hkra machyi shangun ai.

(4)

RFID gaw grau kaba ai application ni hpe lu la mayu yang, manu jahpu hpe grau shayawm ra ai. Hpa majaw nga yang, aten law law hta masha ni gaw RFID hpaji masa a matu myit n lawm ai raitim, electronic tags ni a hpang na manu kaba ai n-gun hpe hkap la na matu yak nga ai. Ya gaw conductive ink hpaji gaw RFID application ni hpe manu jahpu n-gun yawm mat hkra galaw ya lu ai, RFID antenna ni a galaw shapraw ai manu hpe grai shayawm ya lu ai. RFID antenna galaw shapraw ai lam hte rawt jat galu kaba wa ai laika ka hpaji ni hpe kahkyin gumdin ai lam gaw htawm hpang de grau ni wa na hpe tau hkrau chye lu ai.

Conductive ink hte printing hpaji hpe gyin shalat ai hte rau, RFID dip shapraw ai antenna hpaji hpe grau nna hkap la na re. Ndai lam gaw RFID tags ni a manu hpe shayawm ya lu ai, dai hku nna RFID a application threshold hpe shayawm kau ya lu ai, RFID hpaji masa hpe hkan sa ai lam hpe n-gun jaw ya ai, prat masa yawng hta Internet a lam hpe lawan dik ai hku du wa na ahkang jaw ai.
