Gain effective area
WebThe effective area of receiving antenna is the ratio of power delivered to the load to the incident power density: (7.15) In a more general way, the maximum effective area of the receiving antenna can be related to the directivity: (7.16) WebFor a fixed effective aperture, the antenna gain is inversely proportional to the square of the wavelength. The gain expressed in dBi ( GdB) is. G d B = 10 log 10 G = 10 log 10 ( 4 π A g λ 2). The effective antenna aperture can be derived from the gain in …
