Nidaamyada isgaarsiinta microwave-ka, faa'iidada anteenada ayaa ah tilmaame muhim ah oo lagu cabbirayo waxqabadka shucaaca. Xirfadle ahaanalaab-qeybiyaha anteenada microwave, Waxaan si fiican u ognahay muhiimadda ay leedahay in si sax ah loo xisaabiyo loona cabbiro faa'iidada anteenada ee hagaajinta nidaamka. Maqaalkani wuxuu qaadan doonaa40GHz anteenoiyoAnteenada cassegraintusaale ahaan si aan si faahfaahsan u soo bandhigno habka xisaabinta iyo qodobbada la taaban karo ee faa'iidada anteenada.
1. Saldhig xisaabinta aragtida
Faa'iidada anteenada (dBi) waxaa lagu go'aamiyaa jiheynta iyo hufnaanta:
Gain (dBi) = toosnaanta × hufnaanta
1. Xisaabinta jihaynta:
Marka la isku daro qaabka shucaaca, anteenooyinka jihaynta sare leh (sida anteenooyinka Cassegrain) waxay xooga saari karaan tamarta iftiinka cidhiidhiga ah.
2. Tixgelinta waxtarka:
Qodobada khasaaraha soo socda ayaa loo baahan yahay in la tixgeliyo:
- Luminta quudiyaha (sida mawjadaha hagaha oo is barbar dhigin)
- Wax lumin
- Saxnaanta farsamaynta dusha sare
2. Hababka cabbiraadda xirfadlayaasha
1. Habka tijaabada isbarbardhigga:
Is barbar dhig anteenada tijaabada ku jirta (sida anteenada 40GHz) iyo anteenada faa'iidada caadiga ah.
2. Imtixaanka garoonka fog:
Ku cabbir qaabka shucaaca qolka mugdiga ah ee microwave-ka, kaas oo ah hab tijaabo ah oo xirfad leh oo ay badanaa isticmaalaan ** alaab-qeybiyeyaasha anteenada ***.
3. Tijaabada falanqaynta shabakada:
Qiimee luminta soo noqoshada iyo waxtarka shucaaca iyada oo loo marayo falanqaynta cabbirka S.
Anteenada Horn Broadband(18-40GHz)
Waveguide to Coaxial Adapter (26.5-40GHz)
Waveguide Probe Antenna(26.5-40GHz)
RFmiso40Ghz Alaabta Anteenada
3.Tignoolajiyada xaqiijinta jilitaanka
Isticmaal softiweerka jilitaanka korantada ee xirfadleyda ah sida HFSS iyo CST:
- Si sax ah u xisaabi hufnaanta aperture-ka (gaar ahaan muhiim u ah ** Anteenada Cassegrain ** iyo anteenooyinka kale ee milicsiga)
- Falanqaynta toosinta quudinta
- Qiimee saamaynta **hagaharar ***
4. Qodobbada muhiimka ah ee ku dhaqanka injineernimada
1. Tilmaamaha soo noqnoqda:
Faa'iidada anteenada waxay leedahay xiriir la taaban karo oo soo noqnoqda (sida faa'iidada anteenada 40GHz waxay ku yaraan doontaa 30GHz).
2. Arrimaha deegaanka:
Goobta rakibaadda, faragelinta ku xeeran, iwm. waxay saameyn doontaa waxqabadka dhabta ah ee faa'iidada.
3. Shuruudaha habraaca:
Mashiinka saxda ah wuxuu hubinayaa in naqshadeynta aragtida la xaqiijin karo.
Anteenada Cassegrain (26.5-40GHz)
Talo xirfadeed:
Shuruudaha gaarka ah sida ** 40GHz anteeno *** ee band-wave millimeter ama ** Cassegrain anteenada ** oo leh faa'iido sare, waxaa lagu talinayaa in lala kaashado xirfadle ** alaab-qeybiyaha anteenada microwave ** leh awood tijaabo oo dhameystiran si loo hubiyo waxqabadka badeecada.
Waxaan leenahay:
- Qolka imtixaanka oo dhammaystiran
- Kooxda cabbiraadda xirfadlayaasha
- Khibrad injineernimo oo qani ah
