I. Cov Kav Hlau Ua Los Ntawm Cov Khoom Siv Ceramic
Cov txiaj ntsig
•Loj Me Me: Cov khoom siv ceramic uas muaj dielectric constant (ε) siab ua rau muaj qhov me me thaum tswj kev ua tau zoo, zoo tagnrho rau cov khoom siv uas muaj qhov chaw txwv (piv txwv li, Bluetooth earbuds, wearables).
Muaj Peev Xwm Sib Koom Siab:
•Cov Kav Hlau Monolithic Ceramic: Cov qauv ceramic ib txheej nrog cov cim hlau luam tawm ntawm qhov chaw, ua kom yooj yim rau kev sib koom ua ke.
•Antennas Ceramic ntau txheej: Siv cov thev naus laus zis Low-Temperature Co-fired Ceramic (LTCC) los muab cov xov hlau tso rau hauv cov khaubncaws sab nraud povtseg, ua kom qhov loj me me dua thiab ua rau muaj kev tsim cov kav hlau txais xov zais.
•Kev Tiv Thaiv Zoo Dua Rau Kev Cuam Tshuam: Txo qhov kev tawg ntawm electromagnetic vim yog qhov dielectric tas mus li siab, txo qhov cuam tshuam ntawm suab nrov sab nraud.
•Kev Haum Xeeb Rau Zaus Siab: Zoo rau cov bands siab (piv txwv li, 2.4 GHz, 5 GHz), ua rau lawv zoo tagnrho rau Bluetooth, Wi-nkaus, thiab IoT daim ntawv thov.
Qhov tsis zoo
•Bandwidth nqaim: Muaj peev xwm txwv tsis pub npog ntau qhov zaus, txwv tsis pub muaj kev hloov pauv ntau yam.
•Kev Tsim Qauv Nyuaj Siab: Yuav tsum tau kev koom ua ke thaum ntxov rau hauv qhov layout motherboard, tawm me ntsis chaw rau kev hloov kho tom qab tsim.
•Tus nqi siab dua: Cov ntaub ntawv ceramic tshwj xeeb thiab cov txheej txheem tsim khoom tshwj xeeb (piv txwv li, LTCC) ua rau cov nqi tsim khoom nce ntxiv piv rau PCB antennas.
II. Cov Kav Hlau PCB
Cov txiaj ntsig
•Tus nqi qis: Sib xyaw ncaj qha rau hauv PCB, tshem tawm cov kauj ruam sib dhos ntxiv thiab txo cov nqi khoom siv / cov nqi zog ua haujlwm.
•Kev Siv Tau Zoo Ntawm Qhov Chaw: Tsim ua ke nrog cov kab ke ntawm lub voj voog (piv txwv li, FPC antennas, luam tawm inverted-F antennas) kom txo qhov chaw.
•Kev Tsim Qauv Yooj Yim: Kev ua tau zoo tuaj yeem ua kom zoo dua los ntawm kev kho qhov ntev ntawm cov qauv geometry (ntev, dav, meandering) rau cov zaus tshwj xeeb (piv txwv li, 2.4 GHz).
•Kev Ruaj Khob Mechanical: Tsis muaj cov khoom uas raug nthuav tawm, txo qhov kev pheej hmoo ntawm kev puas tsuaj rau lub cev thaum lub sijhawm tuav lossis ua haujlwm.
Qhov tsis zoo
•Kev Ua Haujlwm Tsawg Dua: Kev poob ntawm kev ntxig siab dua thiab kev ua haujlwm ntawm lub zog hluav taws xob txo qis vim yog kev poob ntawm PCB substrate thiab kev sib ze rau cov khoom muaj suab nrov.
•Cov Qauv Hluav Taws Xob Tsis Zoo Tshaj Plaws: Nyuaj rau kev ua tiav omnidirectional lossis sib npaug ntawm cov hluav taws xob, tej zaum yuav txwv qhov ntau ntawm cov teeb liab.
•Kev Cuam Tshuam Rau Kev Cuam Tshuam: Muaj kev phom sij rau kev cuam tshuam hluav taws xob (EMI) los ntawm cov voj voog sib ze (piv txwv li, cov kab hluav taws xob, cov teeb liab ceev ceev).
III. Kev Sib Piv Txog Qhov Xwm Txheej ntawm Daim Ntawv Thov
| Feature | Cov Kav Hlau Ua Los Ntawm Cov Khoom Siv Ceramic | PCB Antennas |
| Zaus Band | Zaus siab (2.4 GHz/5 GHz) | Zaus siab (2.4 GHz/5 GHz) |
| Kev Sib Txuas Lus Sub-GHz | Tsis haum (xav tau qhov loj dua) | Tsis haum (tib qho kev txwv) |
| Cov Qauv Siv Ib Txwm Muaj | Cov khoom siv me me (piv txwv li, cov khoom hnav tau, cov khoom siv kho mob) | Cov qauv me me uas pheej yig (piv txwv li, Wi-Fi modules, cov khoom siv IoT rau cov neeg siv khoom) |
| Tus nqi | Siab (nyob ntawm cov khoom siv/txheej txheem) | Qis |
| Kev Tsim Qauv Yooj Yim | Qis (yuav tsum tau koom ua ke theem thaum ntxov) | Siab (tom qab tsim qauv kho tau) |
IV. Cov Lus Qhia Tseem Ceeb
•Nyiam Ceramic Antennasthaum:
Kev ua kom me me, kev ua haujlwm siab, thiab kev tiv thaiv EMI yog qhov tseem ceeb (piv txwv li, cov khoom siv hnav tau me me, cov nodes IoT ceev ceev).
•Nyiam PCB Antennasthaum:
Txo tus nqi, ua qauv sai, thiab ua tau zoo nruab nrab yog qhov tseem ceeb (piv txwv li, cov khoom siv hluav taws xob uas tsim tawm ntau heev).
•Rau Sub-GHz Bands (piv txwv li, 433 MHz, 868 MHz):
Ob hom kav hlau txais xov no tsis yooj yim siv vim yog qhov loj me ntawm cov nthwv dej. Cov kav hlau txais xov sab nraud (piv txwv li, helical, whip) raug pom zoo.
