In conclusion,passive and active antennas have a few key differences. Passive antennas passively collect energy from the surrounding environment, while active antennas amplify and convert energy into radio waves in order to send signals. Active antennas are generally more efficient and provide better signal quality, but they can also be more expensive to purchase and maintain. It is important to choose the right antenna for your needs, depending on the type of signal you want to transmit and the environment in which you plan to use it.
