Kuti muwonjezere mphamvu ya chizindikiro cha antenna mu makina a microwave, yang'anani kwambiri pa kukonza kapangidwe ka antenna, kasamalidwe ka kutentha, komanso kupanga molondola. Nazi njira zotsimikizika zowonjezerera magwiridwe antchito:
1. Konzani Kupeza ndi Kuchita Bwino kwa Antena
Gwiritsani ntchito ma Antenna a Horn Okhala ndi Gain Yaikulu:
Ma antenna a horn opangidwa mwapadera okhala ndi njira yolondola ya antenna ya horn (monga, corrugated flares) amatha kupeza phindu la >20 dBi, kuchepetsa kutayika kwa chizindikiro.
Mbali Yaikulu: Kusintha kwa ma waveguide opindika kumachepetsa VSWR (<1.5).
2. Kukonza Kutaya kwa Kutentha
Mbale Zoziziritsidwa ndi Madzi Zopangidwa ndi Microchannel Vacuum:
Chepetsani kukana kutentha (<0.05°C/W), zomwe zimalola mphamvu zambiri zolowera popanda kuchepetsa mphamvu.
Ubwino: Zimaletsa kuwonongeka kwa makina a 5G/mmWave amphamvu kwambiri.
3. Kukweza Zinthu ndi Kupanga
Nsalu ya Antena Yotsika Mtengo:
Nsalu zoyendetsera magetsi (monga nayiloni yokutidwa ndi siliva) zimapangitsa kuti ma antenna osinthasintha azigwira ntchito bwino ndi 15%+.
Zabwino kwambiri pa: Mauthenga ovalidwa, mapulogalamu a UAV.
4. Chepetsani Kusokoneza kwa Zizindikiro
Kukonza Ndege Yapansi:
Chowunikira chopangidwa bwino chimawonjezera chiŵerengero cha kutsogolo ndi kumbuyo (>30 dB).
Ma Feedline Otetezedwa:
Letsani EMI kuti isawononge zizindikiro zofooka.
Kodi ndingatani kuti chizindikiro cha antenna yanga chikhale cholimba?
5. Kusankha molondola ndi kufananiza zochitika za pulogalamuyo
Sankhani njira yabwino kwambiri ya antenna yogwirizana ndi zofunikira zosiyanasiyana za makina: Malo oyambira a 5G amalimbikitsa kugwiritsa ntchito ma antenna a nyanga yopangidwa mwaluso (Custom Horn Antenna) okhala ndi ma plates ozizira a microchannel vacuum brazed (Microchannel Vacuum Brazed Water-Cooled Plate), omwe amatha kupeza phindu lokhazikika la 25-30dBi; kulumikizana kwa satellite kumakonda ma feed a parabolic okhala ndi polarized, ndi phindu la 35-45dBi; machitidwe ankhondo ophatikizidwa amafunikira ma antenna a unit okhala ndi ukadaulo wophatikizana wa brazing heat dissipation, ndi phindu la unit la 20-25dBi. Posankha, ndikofunikira kuganizira mokwanira ma frequency, mphamvu yamagetsi komanso kusinthasintha kwa chilengedwe, ndikutsimikizira kufanana kwa impedance kudzera mu vector network analyzer kuti muwonetsetse mphamvu yayikulu ya chizindikiro.
Kuti mudziwe zambiri zokhudza ma antenna, chonde pitani ku:
