Ukuthelekiswa kweeAntenna zeCeramic vs. PCB Antennas: Izinto eziluncedo, ezingeloncedo, kunye neemeko zeSicelo

...I. Iintenna zeCeramic...

...Iingenelo...

•Ubungakanani obuChwethekileyo obuphezulu: Idielectric engaguquguqukiyo (ε) yemathiriyeli yeceramic yenza i-miniaturization ebalulekileyo ngelixa igcina ukusebenza, ilungele izixhobo ezibambekayo (umzekelo, ii-earbuds zeBluetooth, izinto ezinxitywayo).

...Ukukwazi ukuDityaniswa okuphezulu:

•I-Monolithic Ceramic Antennas: Isakhiwo se-ceramic yomgangatho omnye kunye nemigca yesinyithi eprintwe kumphezulu, yenza lula ukudibanisa.
•Multilayer Ceramic Antennas: Isebenzisa itekhnoloji ye-Low-Temperature Co-fired Ceramic (LTCC) ukushumeka ii-conductor kwiileya ezipakishweyo, ukunciphisa ngakumbi ubungakanani kunye nokuvumela uyilo olufihliweyo lwe-eriyali.

•Ukomelezwa koKhuseleko kuphazamiseko: Ukucutha ukusasazeka kwe-electromagnetic ngenxa yokungaguquguquki kwe-dielectric, ukunciphisa impembelelo yengxolo yangaphandle.
•High-Frequency Ukufaneleka: Ilungiselelwe iibhendi zefrikhwensi ephezulu (umz., 2.4 GHz, 5 GHz), izenza zilungele iBluetooth, iWi-Fi, kunye ne-IoT usetyenziso.

...Iingxaki

•Ububanzi obumxinwa: Ukungakwazi ukugubungela iibhendi zamaza amaninzi, ukuthintela ukuguquguquka.
•Ukuntsonkotha koYilo oluPhezulu: Ifuna ukudityaniswa kwenqanaba lokuqala kwibhodi yomama, ishiya indawo encinci yohlengahlengiso lwasemva koyilo.
•Iindleko eziphezulu: Izinto ezenziwe ngokwezifiso ze-ceramic kunye neenkqubo zokwenziwa ezikhethekileyo (umzekelo, i-LTCC) zonyusa iindleko zemveliso xa kuthelekiswa nee-eriyali ze-PCB.

...II. PCB Antenna...

...Iingenelo...

•Ixabiso eliphantsi: Idityaniswe ngokuthe ngqo kwi-PCB, kususwa amanyathelo awongezelelweyo endibano kunye nokunciphisa iindleko zemathiriyeli/zabasebenzi.
•Ubuchule beSithuba: Idityaniswe ngokudibeneyo kunye nomkhondo wesekethe (umzekelo, ii-eriyali ze-FPC, i-eriyali eprintiweyo e-inverted-F) ukunciphisa unyawo.
•Uyilo lokuguquguquka: Ukwenziwa komsebenzi kunokuphuculwa ngokulandela umkhondo wejometri tuning (ubude, ububanzi, ukujikeleza) kwiibhendi ezithile zamaza (umz., 2.4 GHz).
•Ukomelela koomatshini: Akukho zixhobo eziveziweyo, ukunciphisa umngcipheko wokulimala komzimba ngexesha lokuphatha okanye ukusebenza.

...Iingxaki

•Ukusebenza okuphantsi: Ilahleko ephezulu yokufaka kunye nokunciphisa ukusebenza kakuhle kwemitha ngenxa yelahleko ye-PCB substrate kunye nokuba kufutshane kumalungu anengxolo.
•Iipateni zeRadiation eziphantsi: Ubunzima ekufezekiseni i-omnidirectional okanye efanayo kwi-radiation coverage, okunokuba nokunciphisa uluhlu lwesignali.
•Ukuba buthathaka kuMphazamiseko: Isesichengeni sokuphazamiseka kombane (i-EMI) ukusuka kwiisekethe ezikufutshane (umzekelo, iintambo zombane, iisignali ezinesantya esiphezulu)....

 

...III. Uthelekiso lwemeko yeSicelo...

...Uphawu...	...Iintenna zeCeramic...	...PCB Antenna...
...Ibhendi yokuphindaphinda...	I-Frequency ephezulu (2.4 GHz/5 GHz)	I-Frequency ephezulu (2.4 GHz/5 GHz)
...I-Sub-GHz iyahambelana...	Ayilunganga (ifuna ubungakanani obukhulu)	Ayilunganga (umlinganiselo ofanayo)
...Iimeko zokuSebenza eziQhelekileyo...	Izixhobo ezincinci (umzekelo, izinto ezinxitywayo, izixhobo zonyango)	Uyilo lwe-compact olungenaxabiso (umzekelo, iimodyuli zeWi-Fi, i-IoT yabathengi)
...Iindleko...	Phezulu (izinto/inkqubo-ixhomekeke)	Phantsi
...Uyilo lokuguquguquka...	Phantsi (udibaniso lwakwangoko luyafuneka)	Phezulu (ulungelelwaniso lwasemva koyilo lunokwenzeka)

...IV. Iingcebiso eziphambili...

•Khetha ii-Antenna zeCeramicnini:
I-Miniaturization, i-high-frequency performance, kunye nokumelana ne-EMI kubaluleke kakhulu (umzekelo, izinto ezinxitywayo ezihlangeneyo, iindawo eziphezulu ze-IoT).
•Khetha ii-Antenna zePCBnini:
Ukuncitshiswa kweendleko, ukuchwetheza okukhawulezileyo, kunye nokusebenza okuphakathi zizinto eziphambili (umzekelo, ii-electronics eziveliswa ngobuninzi zabathengi).
•Kwiibhendi ze-Sub-GHz (umzekelo, 433 MHz, 868 MHz):

Zombini ezi ntlobo ze-eriyali azinakwenzeka ngenxa yemiqobo yobungakanani obuqhutywa ngamaza. Ii-eriyali zangaphandle (umzekelo, i-helical, i-whip) ziyacetyiswa.

Ingqikelelo ibonelela ngoluhlu olupheleleyo lwamacandelo e-microwave esebenzayo yomkhosi, iAerospace, i-Electronic Countermeasures, uNxibelelwano ngeSathelayithi, usetyenziso loNxibelelwano lweTrunking, ii-eriyali: Isahluli samandla, i-coupler eyalathisayo, isihluzi, i-duplexer, kunye nezixhobo ze-PIM EZINGAPHANTSI ukuya kuthi ga kwi-50GHz, ezinomgangatho olungileyo kunye namaxabiso akhuphisanayo.
