Hauv kev tsim lub kav hlau txais xov microwave, qhov nce siab zoo tshaj plaws yuav tsum sib npaug rau kev ua tau zoo thiab kev siv tau yooj yim. Txawm hais tias qhov nce siab tuaj yeem txhim kho lub zog teeb liab, nws yuav coj teeb meem xws li qhov loj me ntxiv, cov teeb meem kev tshem tawm cua sov thiab cov nqi nce ntxiv. Cov hauv qab no yog cov kev xav tseem ceeb:
1. Kev sib phim qhov nce nrog daim ntawv thov
Chaw nres tsheb 5G (millimeter wave AAU):24-28dBi, xav taukev siv lub tshuab nqus tsevphaj dej txias kom ntseeg tau tias lub sijhawm ua haujlwm siab ntev.
Kev sib txuas lus satellite (Ka band):40-45dBi, cia siab rau cov kav dej tooj liab faus rau hauv dej txias kom daws tau qhov teeb meem cua sov ntawm cov kav hlau txais xov loj.
Kev ua tsov rog hluav taws xob / radar:20-30dBi, siv kev sib txhuam vuam kua txias kom hloov kho rau qhov kub siab dynamic.
Kev kuaj EMC:10-15dBi, lub dab dej kub vuam ib txwm muaj peev xwm ua tau raws li qhov xav tau.
Cassegrain Antenna (40dBi)
Antenna Horn Polarized Circularly (20dBi)
2. Kev txwv ntawm kev tsim khoom ntawm qhov nce siab
Lub qhov cua sov uas tsis muaj zog: Cov kav hlau txais xov uas siab tshaj 25dBi feem ntau xav tau kev txias ua kua (xws li kev siv lub tshuab nqus tsev los yog kev sib txhuam vuam siv dej txias), txwv tsis pub lub zog yuav tsawg.
Kev txwv qhov loj me: Cov antennas saum 30dBi yuav tshaj 1 'meter' hauv Ka band, thiab kev tsim qauv yuav tsum tau ua kom zoo dua.
Cov yam ntxwv ntawm tus nqi: Rau txhua qhov nce 3dB, tus nqi ntawm lub kaw lus txias yuav nce ntxiv 20% -30%.

Dual Voj Voog Polarized Horn Antenna (10dBi)
3. Cov lus qhia txog kev txhim kho
Tsom ntsoov rau qhov yuav tsum tau ua kom phim cov ntawv thov thiab zam kev nrhiav kom tau txiaj ntsig ntau dhau.
Cov tshuaj txias txiav txim siab lub peev xwm fais fab, thiab cov kav hlau txais xov siab yuav tsum tau nruab nrog kev txias zoo (xws li kev txias kua).
Sib npaug ntawm bandwidth thiab gain. Cov kab ke narrowband tuaj yeem nrhiav tau qhov gain siab dua, thiab cov kab ke broadband yuav tsum tau ua qhov kev pom zoo tsim nyog.
Xaus Lus: Qhov nce zoo tshaj plaws nyob ntawm daim ntawv thov tshwj xeeb, feem ntau ntawm 20-35dBi, thiab yuav tsum tau ua ke nrog cov thev naus laus zis txias siab heev (xws li lub tshuab nqus tsev lossis kev sib txhuam vuam dej txias) kom ntseeg tau tias kev ua haujlwm txhim khu kev qha.
