Detailed explanation-1: -2.7 Free-space Propagation: Friis Equation where t and r are the reflection coefficients at the terminals of the transmitting and receiving antennas, Gt and Gr are their respective gains, and FPL is the polarization loss factor due to polarization mismatch between the two antennas, F PL = | ˆ ⋅ ˆ | .
Detailed explanation-2: -The Friis Transmission Equation is used to calculate the power received from one antenna (with gain G1), when transmitted from another antenna (with gain G2), separated by a distance R, and operating at frequency f or wavelength lambda.
Detailed explanation-3: -Explanation: Friss transmission equation is used to calculate the power received by the receiving antenna when transmitted from other antenna separated by a distance R.
Detailed explanation-4: -P R ∝ G × P T f 2 × d , where f is the carrier frequency, d is the propagation distance, G is the power gain from the transmit and receive antennas, and = 2.
