.I. Ceramic Antenna.
.Izinzuzo.
••Usayizi Ohlangene Kakhulu: I-dielectric engaguquguquki ephezulu (ε) yezinto zobumba inika amandla ukwenziwa kancane okubalulekile ngenkathi kugcinwa ukusebenza, ilungele amadivayisi avaleleke esikhaleni (isb., ama-earbud e-Bluetooth, okugqokekayo).
.Ikhono Lokuhlanganisa Eliphezulu:
••I-Monolithic Ceramic Antennas: Isakhiwo se-ceramic esinongqimba olulodwa esinezinsalela zensimbi eziphrintwe ngaphezulu, okwenza ukuhlanganisa kube lula.
••I-Multilayer Ceramic Antennas+
••Ukuvikeleka Okuthuthukisiwe Ekuphazamiseni: Kuncishiswe ukuhlakazeka kwe-electromagnetic ngenxa yokungaguquguquki okuphezulu kwe-dielectric, kunciphisa umthelela womsindo wangaphandle.
••High-Frequency Ukufaneleka: Ilungiselelwe amabhendi efrikhwensi ephezulu (isb, 2.4 GHz, 5 GHz), okuwenza afaneleke kuzinhlelo zokusebenza ze-Bluetooth, i-Wi-Fi, ne-IoT.
.Ukubi
••Umkhawulokudonsa omncane: Ikhono elilinganiselwe lokumboza amabhendi amafrikhwensi amaningi, ukukhawulela ukuhlukahluka.
••High Design Complexity: Idinga ukuhlanganiswa kwesigaba sangaphambi kwesikhathi kusakhiwo sebhodi lomama, okushiya isikhala esincane sokulungiswa kwedizayini yangemuva.
••Izindleko Eziphakeme: Izinto zobumba ezenziwe ngokwezifiso nezinqubo zokukhiqiza ezikhethekile (isb, i-LTCC) zinyusa izindleko zokukhiqiza uma ziqhathaniswa nezimpondo ze-PCB.
.II. PCB Antenna.
.Izinzuzo.
•Izindleko eziphansi: Kuhlanganiswe ngqo ku-PCB, kuqedwe izinyathelo ezengeziwe zomhlangano kanye nokunciphisa izindleko zempahla/zabasebenzi.
•Ukuphumelela Kwesikhala: Idizayinwe ngokuhlanganyela ngemikhondo yesekethe (isb., izimpondo ze-FPC, izinti eziphrintiwe ezi-inverted-F) ukuze kuncishiswe umkhondo.
•Ukuvumelana nezimo: Ukusebenza kungathuthukiswa ngokushuna kwe-trace geometry (ubude, ububanzi, ukuzungeza) kumabhendi athile efrikhwensi (isb., 2.4 GHz).
•Ukuqina Komshini: Azikho izingxenye eziveziwe, ezinciphisa ingozi yokulimala ngokomzimba ngesikhathi sokuphatha noma sokusebenza.
.Ukubi
•Ukusebenza Okuphansi: Ukulahleka kokufakwa okuphezulu kanye nokuncipha kokusebenza kahle kwemisebe ngenxa yokulahleka kwe-PCB substrate kanye nokuba seduze kwezingxenye ezinomsindo.
•I-Suboptimal Radiation Patterns: Ubunzima bokuthola ukumbozwa kwemisebe ye-omnidirectional noma efanayo, okungase kube nomkhawulo webanga lesiginali.
•Ukuba sengozini Kokuphazamiseka: Isengozini yokuphazanyiswa yi-electromagnetic (EMI) evela kumasekhethi aseduze (isb., izintambo zikagesi, amasignali anesivinini esikhulu)..
.III. Isicelo Scenario Ukuqhathanisa.
| .Isici. | .Izimpondo Ze-Ceramic. | .PCB Antenna. |
| .I-Frequency Band. | I-High-frequency (2.4 GHz/5 GHz) | I-High-frequency (2.4 GHz/5 GHz) |
| .Ukuhambisana kwe-Sub-GHz. | Ayifanele (idinga usayizi omkhulu) | Ayifanelekile (umkhawulo ofanayo) |
| .Amacala Okusetshenziswa Okujwayelekile. | Amadivayisi amancane (isb., okugqokekayo, izinzwa zezokwelapha) | Imiklamo ehlangene ezwela izindleko (isb, amamojula e-Wi-Fi, i-IoT yabathengi) |
| .Izindleko. | Phezulu (okubalulekile/okuncike kwinqubo) | Phansi |
| .Ukuvumelana nezimo. | Okuphansi (kudingeka ukuhlanganiswa kwesigaba sokuqala) | Phezulu (ukushuna kwangemuva kokuklama kungenzeka) |
.IV. Izincomo Ezibalulekile.
••Khetha Izintuthwane Ze-Ceramicnini:
I-Miaturization, ukusebenza kwe-high-frequency, kanye nokumelana ne-EMI kubalulekile (isb, okugqokekayo okuhlangene, ama-node e-IoT aphezulu).
••Khetha ama-PCB Antennanini:
Ukwehliswa kwezindleko, i-prototyping esheshayo, nokusebenza okumaphakathi yizinto eziza kuqala (isb., ama-electronics akhiqizwa ngobuningi bomthengi).
••Kumabhendi e-Sub-GHz (isb, 433 MHz, 868 MHz):
Zombili lezi zinhlobo ze-antenna azisebenzi ngenxa yezingqinamba zosayizi oshayelwa i-wavelength. Izinti zangaphandle (isb., i-helical, i-whip) ziyanconywa.
I-Concept inikeza uhla olugcwele lwezingxenye ze-microwave ezingenzi lutho zamasosha, I-Aerospace, I-Electronic Countermeasures, Ukuxhumana Ngesathelayithi, izinhlelo zokusebenza Zokuxhumana Kwe-Trunking, izimpondo: Isihlukanisi samandla, i-directional coupler, isihlungi, i-duplexer, kanye nezingxenye ze-PIM EZIPHANSI ezifika ku-50GHz, ezinekhwalithi enhle nezintengo ezincintisanayo.
