Sebakeng sa puisano e se nang mohala ea 5G, sepheo sa nako e tlang se tla fetohela molemong oa ho sebelisa maqhubu a kaholimo ho 20 GHz ka har'a mmWave spectrum ho ntlafatsa bokhoni ba bandwidth, 'me qetellong se nyolle litekanyetso tsa phetisetso.
Hoa tsebahala hore ka lebaka la maqhubu a bona a phahameng le tahlehelo e kholo ea litsela, matšoao a mmWave a hloka li-antenna tse nyane. Li-antenna tsena li bokelloa hammoho ho etsa li-antenna tse moqotetsane, tse nang le phaello e phahameng.
E 'ngoe ea mathata a mantlha a moralo oa filthara ke ho ikamahanya le maemo a antenna, haholo-holo bakeng sa lihloela tsa maqhubu a holimo. Ho feta moo, mamello ea tlhahiso le botsitso ba mocheso oa li-filters li ama haholo karolo e 'ngoe le e 'ngoe ea moralo oa sehlahisoa le tlhahiso.
Litšitiso tsa boholo ho mmWave Technology
Lits'ebetsong tsa li-antenna tsa setso, sebaka se pakeng tsa likarolo se tlameha ho ba ka tlase ho halofo ea wavelength (λ/2) ho qoba tšitiso. Molao-motheo ona o sebetsa ka mokhoa o ts'oanang ho li-antenna tsa 5G tse benyang. Mohlala, lenakana le sebetsang sehlopheng sa 28 GHz le na le sebaka sa likarolo tse ka bang 5 mm. Ka lebaka leo, likarolo tse ka har'a sehlopha li tlameha ho ba tse nyane haholo.
Li-arrays tse sebelisoang lits'ebetsong tsa mmWave hangata li nka moralo oa sebopeho sa polane, joalo ka ha ho bonts'itsoe ka tlase, moo li-antenna (libaka tse mosehla) li behiloeng holim'a liboto tsa potoloho tse hatisitsoeng (PCBs) (libaka tse tala), le liboto tsa potoloho (libaka tse putsoa) li ka hokahanngoa ka kotloloho boto ea antenna.
Sebaka sa liboto tsena tsa potoloho se se se le nyane, empa mahlale a ntseng a hlaha a ntse a hlahloba meaho e sephara e kopaneng le ho feta, ho bolelang hore li-filters le li-blocks tse ling tsa potoloho li hloka ho ba nyane haholo hore li kenngoe ka morao ho PCB ea antenna.

Moralo oa filthara ea stripline, o bontšitsoeng ka tlase, ke sebopeho sa mekhahlelo e supileng e nang le liboto tsa dielectric tsa 30 mil RO3003 holimo le tlase.
