Antenna Gain Nasıl Hesaplanır?
learn.whatIsHeading
Calculates antenna directivity and gain compared to isotropic radiator. Shows how antenna concentrates power in preferred direction.
Formül
Gain (dBi) = 10 × log10(power density vs. isotropic)
Adım Adım Kılavuz
- 1Gain (dBi) = 10 × log10(power density vs. isotropic)
- 2Omnidirectional antennas 0-3 dBi
- 3Directional antennas 5-20+ dBi
- 4Gain trade-off: narrower pattern = higher gain
- 5Efficiency factor: practical gain < theoretical
Çözümlü Örnekler
Giriş
Dipole antenna
Sonuç
2.15 dBi
Kaçınılması Gereken Yaygın Hatalar
- ✕Confusing antenna gain with amplifier gain
- ✕Not accounting for free space path loss
Sık sorulan sorular
What's the difference between dBi and dBd?
dBi: vs. isotropic point source; dBd: vs. dipole; dBi = dBd + 2.15.
How does antenna gain improve range?
6 dB gain = 2× power (doubles range); 10 dB = 10× power (3.16× range).
