I. Ma Antena a Ceramic
Ubwino
•Kukula Kochepa Kwambiri: Chosasinthika cha dielectric (ε) cha zinthu zadothi chimapangitsa kuti zinthu zisamayende bwino kwambiri pamene zikugwira ntchito bwino, zomwe ndi zabwino kwambiri pa zipangizo zomwe zili ndi malo ochepa (monga ma earbuds a Bluetooth, zovala).
Kutha Kuphatikiza Kwambiri:
•Ma Antena a Monolithic Ceramic: Kapangidwe ka ceramic kamene kali ndi zigawo zachitsulo zosindikizidwa pamwamba, zomwe zimapangitsa kuti kuphatikizana kukhale kosavuta.
•Ma Antena a Ceramic Osiyanasiyana: Amagwiritsa ntchito ukadaulo wa Low-Temperature Co-fired Ceramic (LTCC) kuti alowetse ma conductors m'magawo otsatizana, kuchepetsa kukula ndikuthandizira mapangidwe a antenna obisika.
•Chitetezo Chowonjezereka Chosalowererapo: Kuchepa kwa kufalikira kwa maginito chifukwa cha dielectric constant yayikulu, kuchepetsa phokoso lakunja.
•Kuyenerera Kwambiri: Yakonzedwa bwino kuti ikhale ndi ma band amphamvu kwambiri (monga 2.4 GHz, 5 GHz), zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito Bluetooth, Wi-Fi, ndi IoT.
Zoyipa
•Bandwidth Yopapatiza: Kulephera kochepa kuphimba ma frequency band angapo, zomwe zimalepheretsa kusinthasintha kwa mawu.
•Kuvuta Kwambiri Kwakapangidwe: Imafuna kuphatikizidwa koyambirira mu kapangidwe ka bolodi la amayi, zomwe zimasiya malo ochepa oti zisinthidwe pambuyo pa kapangidwe kake.
•Mtengo WokweraZipangizo zopangidwa ndi ceramic ndi njira zapadera zopangira (monga LTCC) zimawonjezera ndalama zopangira poyerekeza ndi ma antenna a PCB.
II. Ma Antena a PCB
Ubwino
•Mtengo wotsika: Yophatikizidwa mwachindunji mu PCB, kuchotsa njira zina zowonjezera zosonkhanitsira ndikuchepetsa ndalama zogwirira ntchito/zogwirira ntchito.
•Kugwiritsa Ntchito Mwachangu Mu Malo: Yopangidwa pamodzi ndi ma circuit traces (monga ma FPC antenna, ma printed inverted-F antenna) kuti achepetse malo olowera.
•Kusinthasintha kwa KapangidweMagwiridwe antchito amatha kukonzedwa bwino kudzera mu kusintha kwa ma trace geometry (kutalika, m'lifupi, kuzungulira) kwa ma frequency band enaake (monga, 2.4 GHz).
•Kulimba kwa Makina: Palibe zigawo zomwe zawonekera, zomwe zimachepetsa chiopsezo cha kuwonongeka kwakuthupi panthawi yogwira ntchito kapena yogwira ntchito.
Zoyipa
•Kugwira Ntchito Mochepa: Kutayika kwakukulu kwa malo oikirapo zinthu ndi kuchepa kwa mphamvu ya ma radiation chifukwa cha kutayika kwa PCB substrate komanso kuyandikira kwa zinthu zomwe zimakhala ndi phokoso.
•Mawonekedwe Osakwanira a Radiation: Kuvuta kupeza kufalikira kwa ma radiation mbali zonse kapena mofanana, zomwe zingachepetse kuchuluka kwa zizindikiro.
•Kusokonezeka ndi Kusokoneza: Yosavuta kusokonezedwa ndi ma electromagnetic interference (EMI) ochokera m'mabwalo oyandikana nawo (monga, ma power lines, ma high speed signals).
III. Kuyerekeza kwa Zochitika Zogwiritsira Ntchito
| Mbali | Ma antenna a Ceramic | Ma antenna a PCB |
| Band Yobwerezabwereza | Ma frequency apamwamba (2.4 GHz/5 GHz) | Ma frequency apamwamba (2.4 GHz/5 GHz) |
| Kugwirizana kwa Sub-GHz | Sikoyenera (imafuna kukula kwakukulu) | Sikoyenera (zoletsa zomwezo) |
| Milandu Yogwiritsidwa Ntchito Kawirikawiri | Zipangizo zazing'ono (monga zovala, masensa azachipatala) | Mapangidwe ang'onoang'ono omwe amakhudza mtengo (monga ma module a Wi-Fi, IoT ya ogula) |
| Mtengo | Zapamwamba (zodalira zinthu/njira) | Zochepa |
| Kusinthasintha kwa Kapangidwe | Zochepa (kuphatikiza koyambirira kumafunika) | Kukonza kwakukulu (kungatheke pambuyo pa kapangidwe) |
IV. Malangizo Ofunika
•Mumakonda ma antenna a Ceramicliti:
Kuchepetsa mphamvu zamagetsi, kugwira ntchito pafupipafupi, komanso kukana kwa EMI ndizofunikira kwambiri (monga zovala zopapatiza, ma node a IoT okhala ndi kuchuluka kwakukulu).
•Mumakonda ma Antena a PCBliti:
Kuchepetsa mtengo, kupanga zinthu mwachangu, komanso kugwira ntchito pang'ono ndizofunikira kwambiri (monga zamagetsi zomwe zimapangidwa ndi ogula ambiri).
•Kwa Ma Sub-GHz Bands (monga, 433 MHz, 868 MHz):
Mitundu yonse iwiri ya ma antenna ndi yosagwira ntchito chifukwa cha kukula kwake komwe kumayendetsedwa ndi mafunde. Ma antenna akunja (monga helical, whip) amalimbikitsidwa.
Concept imapereka mitundu yonse ya zida zogwiritsira ntchito ma microwave zomwe sizigwira ntchito zankhondo, zamlengalenga, zamagetsi, zakulankhulana ndi satelayiti, za Trunking Communication, ma antenna: Power divider, directional coupler, fyuluta, duplexer, komanso zida zotsika mtengo za LOW PIM mpaka 50GHz, zokhala ndi mitengo yabwino komanso yopikisana.
