Smart antennas are antenna arrays or antenna classes. Smart processing algorithms are used for spatial signal recognition signature here. A smart antenna takes advantage of the impact of diversity on the (transmitter) source, the destination (receiver), or both. The influence of diversity includes the transmission and/or reception of To increase data speed and multiple radio frequency (RF) waves Reduce the rate of error. The technology of smart antennas can overcome these power limits as well as boost signal quality and let mobile phones use less power to run. The intelligent antenna is also known as antennas with the adaptive array, MIMO, and multiple antennas.
