5 GHz omni anteeno
1.1 Qeexida Saldhigga Saldhigga Anteenada Saldhigga ayaa ah gudbiye beddela hirarka la hagayo ee ku faafinaya khadka iyo meesha bannaan ee hirarka korantada.Waxa laga dhisay saldhiga saldhiga.Shaqadiisu waa inay gudbiso calaamadaha hirarka elektromagnetic ama ay hesho calaamadaha.1.2 Kala soocidda Saldhigga Saldhigga Anteenooyinka Saldhigga anteenooyinka saldhigga waxaa loo qaybiyaa anteenooyin dhan walba iyo anteenooyin jihayn sida jihada, waxaana loo qaybin karaa anteenooyin hal-polarized ah iyo anteenooyin laba-polarized ah iyadoo loo eegayo sifooyinka polarization-ka (polarization of anteenadu waxay tilmaamaysaa jihada xoogga beerta korantada ee la sameeyo marka anteenadu soo baxdo. Marka xoogga goobta korantada ay jihadu u siman tahay dhulka, mowjadda raadiyaha waxaa loo yaqaan mowjadda polarized vertical;marka jihada xoogga korontadu ay barbar socoto dhulka, hirarka raadiyaha waxaa loo yaqaan polarization horizontal. Anteenooyinkooda laba-geeska ah waxay ku kala daboolan yihiin jihooyin toosan iyo kuwo toosan labadaba.Anteenooyinkooda hal-xiran yihiinna waa toosan ama toosan).
2.1 Xaaladda iyo Miisaanka Saldhigga Saldhigga Anteennada Waqtigan xaadirka ah, tirada saldhigyada 4G ee Shiinaha waa qiyaastii 3.7 milyan.Marka loo eego baahiyaha ganacsi ee dhabta ah iyo sifooyinka farsamada, tirada saldhigyada 5G waxay noqon doontaa qiyaastii 1.5-2 jeer marka loo eego saldhigyada 4G.Tirada saldhigyada 5G ee Shiinaha ayaa la filayaa in ay gaaraan 5-7 milyan, waxaana la filayaa in 20-40 milyan oo anteenooyinkooda saldhigga ah loo baahan doono xilliga 5G.Marka loo eego warbixinta Academia Sinica, cabirka suuqa ee anteenooyinka saldhiga saldhiga ee dalkaygu wuxuu gaari doonaa 43 bilyan yuan sanadka 2021 iyo 55.4 bilyan yuan sanadka 2026, oo leh CAGR oo ah 5.2% laga bilaabo 2021 ilaa 2026. Iyadoo ay ugu wacan tahay isbedbedelka wareegyada anteenada saldhigga saldhiga iyo wareegga guud ee gaaban ee xilliga 4G, cabbirka suuqa anteenada ee horraantii xilligii 4G ee 2014 ayaa xoogaa kor u kacay. Ka faa'iidaysiga horumarka xoogga leh ee 5G, waxaa la filayaa in heerka kobaca cabbirka suuqa la filayo inuu kordho.Waxaa la filayaa in cabbirka suuqa uu gaaro 78.74 bilyan yuan sanadka 2023, iyadoo kobaca sanadlaha ah ee isku dhafan uu yahay 54.4%
3.1 Imaanshaha waagii 5G Horumarka degdega ah ee ganacsiga 5G waa mid ka mid ah qodobbada muhiimka ah ee kor u qaadaya horumarinta warshadaha anteenada saldhigga.Tayada anteenada saldhiga saldhiga waxay si toos ah u saamaysaa khibrada isticmaalaha, iyo dhiirigelinta ganacsi ee 5G waxay si toos ah uga qayb qaadan doontaa cusboonaysiinta iyo horumarinta warshadaha anteenada saldhigga.Dhamaadka 2021, wadar dhan 1.425 milyan saldhigyada 5G ayaa laga dhisay oo laga furay dalkayga, iyo tirada guud ee saldhigyada 5G ee dalkaygu waxay ka yihiin in ka badan 60% wadarta guud ee aduunka.Shuruudaha tirada anteenooyinka saldhigga saldhigga: Hoos u dhigidda awoodda anteenada waxay si togan ula xiriirtaa inta jeer ee calaamadda. 5G tamarta anteenada ayaa aad uga sareysa tan 4G.Isla shuruudo la mid ah, daboolida calaamadaha 5G waa rubuc kaliya ee 4G.Si loo gaaro aagga daboolka isku midka ah ee calaamadaha 4G, Nashqada saldhigga ballaaran ayaa loo baahan yahay si loo daboolo xoogga calaamada gudaha aagga daboolka, markaa baahida loo qabo anteenooyinka saldhigga saldhigga ayaa si weyn u kordhin doona.
4.1 Tiknoolajiyada MIMO ee baaxada leh ee MIMO waa tignoolajiyada udub-dhexaadka u ah isgaadhsiinta 4G.Adigoo ku rakibaya anteenooyin badan oo gudbinaya iyo helitaanka anteenooyinkooda aaladaha qalabka, calaamado badan ayaa la diri karaa oo la heli karaa inta u dhaxaysa anteenooyin badan.Marka la eego xaaladda ilaha xaddidan ee xaddidan iyo gudbinta awoodda, Hagaajinta tayada gudbinta calaamadaha oo ballaarisa kanaalada isgaarsiinta. Tiknooloojiyada MIMO ee weyn ee MIMO, oo ku salaysan taageerada asalka ah ee MIMO ee 8 dekedood oo anteeno ah, waxay wanaajisaa daboolida shabakada iyo xasiloonida iyada oo ku daraysa anteenooyin badan si ay u sameeyaan agab cabbir baaxad leh una kordhiyaan awoodda nidaamka. Farsamaynta MIMO ee baaxadda leh waxay shuruudo sare gelisaa anteenooyinka saldhigga saldhigga.Farsamaynta MIMO ee baaxadda leh waxay u baahan tahay in lagu rakibo anteenooyin badan oo si wanaagsan go'doonsan meel qalab xaddidan si loo hubiyo faa'iidada iyo saxnaanta looga baahan yahay samaynta iftiinka. Tignoolajiyadani waxay u baahan tahay in anteenada la yareeyo, oo leh go'doon sare iyo astaamo kale.Waqtigan xaadirka ah, tignoolajiyada anteenada Massive MIMO inta badan waxay qaadataa xal 64-kanaal ah.Tiknoolajiyada 4.2 mmWave Sababtoo ah sifooyinka fogaanta faafinta gaaban iyo hoos u dhigista hirarka 5G milimitir, Qaabaynta saldhigga cufan iyo tignoolajiyada diyaarinta antenna-ballaaran waxay xaqiijin kartaa tayada gudbinta, iyo tirada anteenooyinka hal saldhig oo keliya waxay gaari doonaan tobanaan ama boqolaal.Anteenada dadban ee soo jireenka ah ma khuseyso sababtoo ah khasaaraha gudbinta calaamaduhu aad buu u weyn yahay calaamaduna si habsami leh looguma gudbin karo.
