Ubuchwepheshe bokulwa nokujima kwe-antenna bubhekisela ochungechungeni lwamasu aklanyelwe ukucindezela noma ukuqeda umthelela wokuphazamiseka kwe-electromagnetic yangaphandle (i-EMI) ekudlulisweni nasekutholeni isignali ye-antenna, ukuqinisekisa ukuzinza nokuthembeka kwezinhlelo zokuxhumana. Izimiso eziyinhloko zifaka phakathi ukucubungula i-frequency-domain (isb., ukugxuma kwe-frequency, i-spread spectrum), ukucubungula indawo (isb., ukwenza i-beamforming), kanye nokwenza ngcono ukwakheka kwesekethe (isb., ukufanisa i-impedance). Ngezansi ukuhlukaniswa okuningiliziwe kanye nokusetshenziswa kwalawa matheknoloji.
I. Ubuchwepheshe Bokulwa Nokuvinjelwa Kwe-Antenna
1. Amasu Okulwa Nokuvinjelwa Kwesizinda Esivamile
Ukweqa Okuvama (FHSS):Ishintsha ngokushesha amaza okusebenza (isb., izinkulungwane zezikhathi ngomzuzwana) ukuze igweme amabhande okuphazamisa, avame ukusetshenziswa kwezokuxhumana kwezempi kanye nezinhlelo ze-GPS.
I-Spread Spectrum (i-DSSS/FHSS):Inweba umkhawulokudonsa wesignali kusetshenziswa amakhodi angahleliwe, kunciphisa ubuningi bamandla e-spectral futhi kuthuthukise ukubekezelelana kokuphazamiseka.
2. Amasu Okulwa Nokuvinjelwa Kwendawo
Ama-Antenna Ahlakaniphile (Ukwakheka Kwemisebe Okuvumelana Nezimo):Idala ukungalungi eziqondisweni zokuphazamiseka ngenkathi ithuthukisa ukwamukelwa kwesiginali okufiswayo45. Isibonelo, ama-antenna e-GPS alwa nokujama athuthukisa ukuzinza kokubeka indawo ngokwamukela amaza amaningi kanye nokushintshashintsha kwemisebe.
Ukuhlunga kwe-Polarization:Ivimbela ukuphazamiseka ngokusebenzisa umehluko we-polarization, osetshenziswa kabanzi ekuxhumaneni kwe-radar kanye ne-satellite.
3.Amasu Okulwa Nokuvinjelwa Kwezinga Lesekethe
Umklamo we-Low-Impedance:Isebenzisa impedance eseduze ne-zero-ohm ukudala iziteshi ezincane kakhulu, ihlunga ukuphazamiseka okungenantambo kwangaphandle.
Izingxenye Ezilwa Nokuqhekeka (isb., i-Radisol):Ivimbela ukuphazamiseka kokuxhumanisa phakathi kwama-antenna asondelene kakhulu, ithuthukisa ukusebenza kahle kwemisebe.
II. Ukusetshenziswa Kwezingxenye Ze-Passive Microwave
Izingxenye ze-microwave ezingasebenzi (ezisebenza kububanzi obungu-4–86 GHz) zidlala indima ebalulekile ezinhlelweni zokulwa nokujama kwe-antenna, okuhlanganisa:
Ama-Isolators nama-circulator
Ama-isolator avimbela ukubonakaliswa kwamandla e-RF, avikela ama-transmitter; ama-circulator avumela ukuqondiswa kwesignali, okuvame ukusetshenziswa ezinhlelweni ze-antenna ezabiwe nge-transceiver.
Izingxenye Zokuhlunga
Izihlungi ze-Bandpass/bandstop zisusa ukuphazamiseka kwe-out of-band, njengokuhlunga okuhlakaniphile kuma-antenna e-GPS alwa nokujama
III. Izimo Ezijwayelekile Zokusebenza
Izicelo Zezempi:Ama-radar athwalwa yiziqhumane ahlanganisa ukugxuma okuvama, ukucubungula i-polarization, kanye namasu e-MIMO ukuze kulwiswane nokuminyana okuyinkimbinkimbi.
Ukuxhumana Kwabantu Abavamile:Izingxenye ze-microwave/millimeter-wave passive zivumela ukudluliswa kwesignali yebanga eliphezulu kuzinhlelo ze-5G/6G.
I-Concept Microwave ingumhlinzeki womhlaba wonke wezihlungi ezenziwe ngokwezifisoekusetshenzisweni kwe-Izimoto zasemoyeni ezingenamuntu (ama-UAV) kanye nezinhlelo ze-counter-UAV, okuhlanganisa isihlungi se-lowpass, isihlungi se-highpass, isihlungi se-notch/band stop, isihlungi se-bandpass kanye namabhange okuhlunga.
