Ukadaulo Wotsutsana ndi Kutsekeka kwa Ma Antena ndi Kugwiritsa Ntchito Zigawo Zopanda Ma Microwave

Ukadaulo wotsutsana ndi kugwedezeka kwa ma antenna umatanthauza njira zingapo zomwe zimapangidwa kuti zichepetse kapena kuthetsa mphamvu ya kusokonezedwa kwa ma electromagnetic interference (EMI) pa kutumiza ndi kulandira ma antenna signal, kuonetsetsa kuti njira zolumikizirana zikukhazikika komanso kudalirika. Mfundo zazikuluzikulu zikuphatikizapo kukonza ma frequency-domain (monga, frequency hopping, spread spectrum), spatial processing (monga, beamforming), ndi circuit design optimization (monga, impedance matching). Pansipa pali magulu atsatanetsatane ndi kugwiritsa ntchito matekinoloje awa.

‌I. Ukadaulo Wotsutsana ndi Kutsekeka kwa Ma Antena‌

‌1. Njira Zotsutsana ndi Kusakhazikika kwa Ma Frequency-Domain‌

‌Kudumphadumpha pafupipafupi (FHSS):Imasintha mwachangu ma frequency ogwirira ntchito (monga, nthawi zikwizikwi pa sekondi) kuti ipewe kusokoneza, komwe kumagwiritsidwa ntchito kwambiri mu kulumikizana kwa asitikali ndi machitidwe a GPS.

‌Spread Spectrum (DSSS/FHSS):Amakulitsa bandwidth ya chizindikiro pogwiritsa ntchito ma code olakwika, kuchepetsa kuchuluka kwa ma spectral ndikuwongolera kulekerera kusokoneza.

‌2. Njira Zopewera Kutsekeka kwa Malo‌

‌Ma Antena Anzeru (Kusintha Kuwala):Amasiya njira zosokoneza pamene akuwonjezera kulandiridwa kwa chizindikiro chomwe mukufuna45. Mwachitsanzo, ma antenna a GPS oletsa kugwedezeka amathandizira kukhazikika kwa malo kudzera mu kulandira ma frequency ambiri ndi kupanga kuwala.

‌Kusefa kwa Polarization:Amaletsa kusokoneza pogwiritsa ntchito kusiyana kwa polarization, komwe kumagwiritsidwa ntchito kwambiri mu radar ndi satellite communications.

‌3.Njira Zotsutsana ndi Kutsekereza kwa Dera‌

‌Kapangidwe ka Low-Impedance:Imagwiritsa ntchito near-zero-ohm impedance popanga njira zopapatiza kwambiri, kusefa kusokoneza kwa waya wakunja.

‌Zigawo Zotsutsana ndi Kutsekeka (monga Radisol):Zimaletsa kusokonezana pakati pa ma antenna omwe ali pafupi, zomwe zimapangitsa kuti ma radiation agwire bwino ntchito.

‌II. Kugwiritsa Ntchito Zigawo za Maikrowevu Opanda Mphamvu‌

Zigawo za microwave zomwe sizigwira ntchito (zomwe zimagwira ntchito mu 4–86 GHz) zimagwira ntchito yofunika kwambiri mu machitidwe oletsa kugwedezeka kwa ma antenna, kuphatikizapo:

‌Zodzipatula ndi Zozungulira‌

Zodzipatula zimaletsa kuwunikira kwa mphamvu ya RF, kuteteza ma transmitter; zozungulira zimathandiza kuti chizindikiro chizitsogolera, zomwe zimagwiritsidwa ntchito kwambiri mu makina a antenna omwe amagawana ndi transceiver.

‌Zigawo zosefera‌

Zosefera za Bandpass/bandstop zimachotsa kusokoneza kwa kunja kwa bandi, monga kusefera mwanzeru mu ma antenna a GPS oletsa kugwedezeka

‌III. Zochitika Zachizolowezi Zogwiritsira Ntchito‌

‌Ntchito Zankhondo:Ma radar oyendetsedwa ndi missile amaphatikiza ma frequency hopping, polarization processing, ndi njira za MIMO kuti athane ndi zovuta.

‌Kulankhulana ndi Anthu Osauka:Zigawo zosagwira ntchito za microwave/millimeter-wave zimathandiza kutumiza chizindikiro champhamvu kwambiri mu machitidwe a 5G/6G.

Concept Microwave ndi kampani yogulitsa zosefera zomwe zasinthidwa padziko lonse lapansi.mu ntchito zaMagalimoto amlengalenga opanda anthu (UAVs) ndi makina otsutsana ndi UAV, kuphatikizapo fyuluta ya lowpass, fyuluta ya highpass, fyuluta ya notch/band stop, fyuluta ya bandpass ndi mabanki a fyuluta.
