Kusanthula kwa Njira Zitatu Zopangira Ma RFID Antennas

Ma antenna a RFID amagwiritsidwa ntchito pazinthu zapadera. Pakadali pano, nthawi zambiri pali njira zitatu zazikulu zopangira. Nkhaniyi ikupereka kusanthula mwachidule kwa njirazi, kuphatikizapo njira zopangira komanso zabwino ndi zoyipa zake.

1. Njira Yokhotakhota ya Coil

Popanga ma antenna a RFID tag pogwiritsa ntchito njira yozungulira ma coil, waya wa antenna umazunguliridwa mozungulira chida chozungulira chomwe chimapangidwa mwapadera kenako n’kukhazikika pamalo pake. Njirayi imafuna kuzungulira kwakukulu mu coil ya antenna. Coil ikhoza kupangidwa kukhala chizungulire chozungulira kapena chizungulire chamakona anayi.

Njira iyi nthawi zambiri imagwiritsidwa ntchito pa ma RFID tag omwe amagwira ntchito mu 125–134 kHz frequency range.

Zoyipa za njira yopangira iyi ndizodziwikiratu, makamaka kuphatikiza:

• Mtengo wokwera wopanga

• Kugwiritsa ntchito bwino zinthu zochepa

• Kusasinthasintha kwa chinthucho pambuyo pokonza

2. Njira Yopangira

Njira yocheka nthawi zambiri imagwiritsa ntchito mkuwa kapena aluminiyamu popanga antenna. Njira yopangirayi ndi yofanana ndi njira yocheka yomwe imagwiritsidwa ntchito mu ma flexible printed circuit boards (FPC).

Kujambula kungagwiritsidwe ntchito popanga ma tag amagetsi ambiri omwe amagwira ntchito pa 13.56 MHz komanso mu gulu la ma frequency la UHF. Ubwino wake ndi monga:

• Mawonekedwe abwino a dera

• Kusagwira ntchito bwino

• Kukana kwabwino kwa nyengo

• Kugwira ntchito kwa chizindikiro chokhazikika

Komabe, zovuta zake zikuwonekeranso, monga:

• Njira zovuta zopangira

• Mphamvu yotsika kwambiri yopangira

3. Njira Yosindikizira

Ma antenna osindikizidwa amapangidwa mwa kusindikiza mwachindunji inki yoyendetsa pa chinthu choteteza kutentha (kapena filimu) kuti apange ma antenna oyendetsera magetsi. Njira zosindikizira zasintha kuchokera ku kusindikiza kwachikhalidwe mpaka kuphatikiza kusindikiza kwa offset, kusindikiza kwa flexographic, kusindikiza kwa gravure, ndi njira zina.

Njira yosindikizira ndi yoyenera kupanga ma tag amagetsi ambiri omwe amagwira ntchito pa 13.56 MHz komanso mu gulu la ma frequency la UHF RFID.

Khalidwe lake lalikulu ndi liwiro lalikulu lopanga. Komabe, chifukwa inki yoyendetsa imapanga ma circuits okhala ndi kukana kwakukulu, kuchuluka kwa momwe imagwiritsidwira ntchito kumakhala kochepa.

Kupita patsogolo kwa ukadaulo wa antenna wosindikizidwa kwachepetsa mtengo wa ma tag a RFID, motero kwalimbikitsa kugwiritsa ntchito ma RFID ambiri.
