Theknoloji ea ho thibela ho qhalana ha antenna e bolela letoto la mekhoa e etselitsoeng ho thibela kapa ho felisa tšusumetso ea tšitiso ea motlakase ea kantle (EMI) phetisong le kamohelong ea lets'oao la antenna, ho netefatsa botsitso le ts'epo ea litsamaiso tsa puisano. Melao-motheo ea mantlha e kenyelletsa ts'ebetso ea frequency-domain (mohlala, ho hop frequency, spread spectrum), ts'ebetso ea sebaka (mohlala, beamforming), le ntlafatso ea moralo oa potoloho (mohlala, ho bapisa impedance). Ka tlase ke karohano e qaqileng le ts'ebeliso ea mahlale ana.
I. Theknoloji ea ho Thibela ho Jamming ea Antenna
1. Mekhoa ea ho Thibela ho Jamming ea Frequency-Domain
Ho Tlola Hangata (FHSS):E fetola maqhubu a tshebetso ka potlako (mohlala, makhetlo a dikete ka motsotsoana) ho qoba dihlopha tsa tshitiso, tse sebediswang haholo dipuisanong tsa sesole le ditsamaisong tsa GPS.
Sekhahla sa ho Hasana (DSSS/FHSS):E atolosa bandwidth ea lets'oao ho sebelisoa likhoutu tsa bohata tse sa reroang, e fokotsa bongata ba spectral ea matla le ho ntlafatsa mamello ea tšitiso.
2. Mekhoa ea ho Thibela ho Thibela Sebaka
Li-Antenna tse Bohlale (Li-Beamforming tse Ikamahanyang le Maemo):E etsa hore ho se be le tšitiso ha e ntse e ntlafatsa kamohelo ea lets'oao e lakatsehang45. Mohlala, li-antenna tsa GPS tse thibelang ho jamming li ntlafatsa botsitso ba ho beha ka ho amohela maqhubu a mangata le ho etsa mahlaseli.
Ho sefa polarization:E thibela tšitiso ka ho sebelisa liphapang tsa polarization, tse sebelisoang haholo puisanong ea radar le sathelaete.
3.Mekhoa ea ho Thibela ho Jamming ea Boemo ba Potoloho
Moralo o sa Felleng ka ho Fella:E sebelisa impedance e haufi le zero-ohm ho theha liteishene tse tšesaane haholo, e sefa tšitiso ea waelese ea kantle.
Likarolo tse Khahlanong le ho Jamming (mohlala, Radisol):E thibela tšitiso ea ho kopanya pakeng tsa li-antenna tse haufi-ufi, e ntlafatsa ts'ebetso ea mahlaseli.
II. Litšebeliso tsa Likarolo tsa Microwave tse sa Fetoheng
Likarolo tsa microwave tse sa sebetseng (tse sebetsang ka har'a mefuta ea 4–86 GHz) li bapala karolo ea bohlokoa lits'ebetsong tsa ho thibela ho thothomela ha antenna, ho kenyeletsoa:
Li-Isolator le Li-circulator
Li-isolator li thibela ho bonahatsa matla a RF, li sireletsa li-transmitter; li-circulator li nolofalletsa tataiso ea lets'oao, e sebelisoang hangata lits'ebetsong tsa antenna tse arolelanoang ka transceiver.
Likarolo tsa ho Sefa
Li-filter tsa Bandpass/bandstop li tlosa tšitiso e tsoang kantle ho sehlopha, joalo ka ho sefa ka bohlale ho li-antenna tsa GPS tse thibelang ho jamming
III. Maemo a Tloaelehileng a Tšebeliso
Likopo tsa Sesole:Li-radar tse tsamaisoang ke limisaele li kopanya ho tlola-tlola ha maqhubu, ts'ebetso ea polarization, le mekhoa ea MIMO ho loantša ho thothomela ho rarahaneng.
Puisano ea Sechaba:Likarolo tse sa sebetseng tsa microwave/millimeter-wave li nolofalletsa phetiso ea lets'oao la maqhubu a phahameng lits'ebetsong tsa 5G/6G.
Concept Microwave ke mofani oa lefats'e ka bophara oa li-filters tse etselitsoeng motho ka monglits'ebetsong tsaLikoloi tse se nang bapalami (li-UAV) le litsamaiso tsa counter-UAV, ho kenyeletsoa le sefe sa lowpass, sefe sa highpass, sefe sa notch/band stop, sefe sa bandpass le libanka tsa sefe.
