So indicate that as P subscript t transmit power this is the transmitted power. So, we define for this antenna for a isotropic radiator; isotropic antenna is our point topic of discussion now, the power flux density this is the total power that is radiated experienced at a unit area at a radius R.
तो, एक आइसोट्रोपिक रेडिएटर ऐन्टेना के लिए ट्रांसमिटेड पावर Pt है।
