<p>During the past few decades information technologies have been evolving at a tremendous rate causing profound changes to our world and to our ways of living. Emerging applications have opened u[ new routes and set new trends for antenna sensors. With the advent of the Internet of Things (IoT) the adaptation of antenna technologies for sensor and sensing applications has become more important. Now the antennas must be reconfigurable flexible low profile and low-cost for applications from airborne and vehicles to machine-to-machine IoT 5G etc. This reprint aims to introduce and treat a series of advanced and emerging topics in the field of antenna sensors.</p>
