Why is the Gain of the Transmitted Antenna Not Considered in the Solution?

In summary, the received power of an antenna is the measure of the strength of the signal that is received by the antenna. It can be calculated using the Friis transmission equation and is important for determining the range, coverage, and performance of a communication system. The received power can be improved by increasing transmitter power, using higher gain antennas, and minimizing losses in the transmission medium. Other methods such as antenna diversity and beamforming can also be used for improvement in specific situations.

The solution does not take into account Gain of transmitted antenna. Why?
From friis eqn, Pr(db)= Pt+Gt+Gr-Lp, but soln. omits Gt

This looks like an error to me, too.
 

1. What is the received power of an antenna?

The received power of an antenna is the measure of the strength of the signal that is received by the antenna. It is usually measured in terms of watts or decibels (dB).

2. How is the received power of an antenna calculated?

The received power of an antenna can be calculated using the Friis transmission equation, which takes into account the transmitter power, antenna gains, distance between the transmitter and receiver, and any losses in the transmission medium. Other factors such as atmospheric conditions and antenna directionality may also affect the received power.

3. Why is the received power of an antenna important?

The received power of an antenna is important because it determines the strength of the signal that is received by the antenna. A higher received power means that the signal is stronger, which can improve the quality and reliability of the communication. It is also important for determining the range and coverage of an antenna.

4. How does the received power of an antenna affect the performance of a communication system?

The received power of an antenna directly affects the performance of a communication system. A higher received power can result in a stronger and clearer signal, leading to better communication. On the other hand, a lower received power can result in a weaker and noisier signal, which can cause communication problems such as dropped calls or disrupted data transmission.

5. How can the received power of an antenna be improved?

The received power of an antenna can be improved by increasing the transmitter power, using higher gain antennas, reducing the distance between the transmitter and receiver, and minimizing losses in the transmission medium. Other methods such as antenna diversity and beamforming can also be used to improve the received power of an antenna in specific situations.
