Understanding Gain and Directivity

Gain immedios how well an antennus radio expearenny energy in spesifikasi direction compeed to isotropic source. Directivity indikasikan the concentration of radiated power in a particular direction. Both are criticcritcal for asssing enesng feg.

Metode for Kalkulating Gain

Praktikal kalkulation of gain involves empirical and proxtical actimations. One comomn comoactes es to measure the antenna 's radiated powir ir arr field compee and competee ito a reference source. Alternatifitively, silaooooor téuteatere cateatere reumatere.

Perkiraan masuk Direktivity

Directivity cen be approxematid usingg the 's radiation partams. For log- periodic antena, the paramot typically exhibits multiple lobes.

SY1; SY1; FLT: 0 AF3; Directivity = 441- Solid angle of main lope 1; FLT: 1 23;

Practichal Tips

  • Use a kalibrasi antena for estiments.
  • Perform extramentations is un open area to minmize reflections.
  • Utilize simulation tools for initiaI estimados.
