Ikoranabuhanga ryo kurwanya gufunga antena risobanura urukurikirane rw'amayeri agamije gukumira cyangwa gukuraho ingaruka zo guhungabanya ingufu z'amashanyarazi (EMI) ku ihererekanya ry'ibimenyetso bya antena no kwakira, bigamije kwemeza ko sisitemu z'itumanaho zihamye kandi zizewe. Amahame y'ingenzi arimo gutunganya frequency-domain (urugero, gusimbuka frequency, spread spectrum), gutunganya space (urugero, beamforming), no kunoza imiterere y'uruziga (urugero, guhuza impedance). Hasi hari uburyo burambuye bwo gushyira mu byiciro no gukoresha ubu buryo.
I. Ikoranabuhanga ryo kurwanya gufunga antena
1. Uburyo bwo kurwanya Jamming mu buryo bwa Frequency-Domain
Gusimbuka inshuro nyinshi (FHSS):Ihindura vuba umurongo ngenderwaho w'imikorere (urugero, inshuro ibihumbi ku isegonda) kugira ngo hirindwe imigozi ikoreshwa cyane mu itumanaho rya gisirikare na sisitemu za GPS.
Umuvuduko w'ikwirakwizwa (DSSS/FHSS):Yagura uburyo bwo gukoresha ikoranabuhanga rya "signal bandwidth" hakoreshejwe "pseudo-random codes", igabanya ubucucike bwa "power spectral" kandi ikongera ubushobozi bwo kwihanganira ingaruka mbi.
2. Uburyo bwo kurwanya gufunga ahantu
Antena zigezweho (Adaptive Beamforming):Ihindura ubusa mu cyerekezo cyo kubangamirana mu gihe yongera uburyo bwo kwakira ibimenyetso45. Urugero, antene za GPS zirwanya guhagarara zinoza uburyo bwo gushyira ibintu mu mwanya wabyo binyuze mu kwakira no gushushanya hakoreshejwe frequency nyinshi.
Gushungura imiterere y'amabara ya polarization:Ikumira ukwivanga kw'ibintu binyuze mu gukoresha itandukaniro rya polarization, rikoreshwa cyane mu itumanaho rya radar na satelite.
3.Uburyo bwo kurwanya gufungana ku rwego rw'uruziga
Igishushanyo mbonera cy'ingufu nke:Ikoresha impedance hafi ya zero-ohm kugira ngo ikore imiyoboro mito cyane, iyungurura interferences zo hanze zidafite umugozi.
Ibice birwanya gushonga (urugero: Radisol):Igabanya uburyo bwo guhuza antene ziri hafi cyane, ikongera imikorere myiza y'imirasire.
II. Imikoreshereze y'Ibice bya Microwave bidakoresha
Ibice bya mikoroonde bidakora (bikora mu rugero rwa 4–86 GHz) bigira uruhare runini muri sisitemu zo kurwanya guhagarara kw'antene, harimo:
Ibikoresho byo Kwambura no Gutembera
Ibikoresho bitandukanya ingufu za RF bibuza kohereza ingufu za RF, bikinga ibyohereza; ibikoresho bizunguruka bitanga icyerekezo cy'ibimenyetso, gikunze gukoreshwa muri sisitemu ya antene ikoreshwa na transceiver.
Ibice byo gushungura
Akayunguruzo ka Bandpass/Bandstop kakuraho ikibazo cyo hanze y'umugozi, nko kuyungurura mu buryo bw'ubwenge muri antene za GPS zirwanya jamming3.
III. Ingero zisanzwe z'ishyirwa mu bikorwa
Ibisabwa mu gisirikare:Radar zitwarwa na misile zihuza uburyo bwo gusimbuka inshuro nyinshi, gutunganya polarization, na tekiniki za MIMO kugira ngo zirwanye uburyo bwo gusimbuka ibintu mu buryo bugoye.
Itumanaho rya gisivili:Ibice bidakoresha mikoroonde/milimetero-wave bitanga uburyo bwo kohereza ibimenyetso mu buryo bwa dynamic-range muri sisitemu ya 5G/6G.
Concept Microwave ni isoko mpuzamahanga ry’ibikoresho byifashishwa mu kuyungurura ibyuma byihariyemu ishyirwa mu bikorwa ryaImodoka zitagira abapilote (UAVs) na sisitemu zo kurwanya UAV, harimo akayunguruzo k'inzira ntoya, akayunguruzo k'inzira nini, akayunguruzo k'inzira ntoya/inyuma, akayunguruzo k'inzira n'impande zombi.
