If you were to make an analogy between a radar and the human body, the antenna on the radar would be the eyes – it sees what the radar detects. There are many different antenna types that exist today and these technologies are continually growing and becoming more complex. The technologies range from the dipole antenna (2 wires), to patch antennas and, most recently, metamaterial antennas that could, in the far future, provide a method for cloaking. Cloaking, in the context of metamaterial cloaking and electromagnetic (EM) radiation, is when the EM field propagates around the object with the metamaterial properties, or in other words it makes the object seem invisible. Aren’t antennas cool?
