Re: Antenna Gain
Antenna Gain= (Radiation resistance)/(loss resiatance+Radiation resistance)
loss resiatance calculated from eddy current loss,copperloss etc..
actually there exists many more formulas to fing Gain of a antenna...
2)high directional antenna will have maximum radiation intensity in particulat direction..that why it is called as high directional antenna
in terms of radiation intensity in particular direction with that of isotropic antennsalso,Gain can be calculated
