The growing communication and computing capabilities in devices widens the connected world and improves human comfort. The evolution of intelligent sensor networks and smart antennas has led to the development of smart devices and systems for real-time monitoring of various environments.

The demand for smart antennas and intelligent sensors significantly increases when dealing with multi-user communication systems that need to be adaptive, especially in an unknown adverse environment. The smart antennas-based arrays are capable of steering the main beam in any desired direction while placing nulls in the unwanted directions. Intelligent sensor networks integration with smart antennas will provide algorithms and interesting applications to collect various data from the environment to make intelligent decisions.

The aim of this Special Issue is to solicit original research articles, highlighting an inclusive vision on the current research area of intelligent sensors and smart antenna-based systems for enabling various applications and technologies. Review articles discussing the current state of the art, are also welcome.
