Sub-millimeter wave nanoantenna-a review

Abstract Electromagnetic waves that have a wavelength of less than one millimeter are referred to as sub waves. In wave-based devices and systems, antennas critical components vital their operation. Antennas used in situations when transition between directed wave free-space is needed. Since, electromagnetic characteristics for receiving transmission the nano antenna mutually invertible, properties analyzed frequencies this overcomes limitations conventional design. They very small size, provide more efficiency, do not cause health threat. This paper reviews applications antenna, which operates at sub-millimeter frequency, field energy harvesting, space technology, IoT applications, 5G network, smart clothing, bio sensing, communication, etc? Also, fabricated by 3D printing technology also reviewed. The world’s ever-increasing need necessitates development alternate sources. There lot research going on right now enhance photovoltaic systems so they can be efficient, but constraint only collect from visible area spectrum. As result, novel device known Nano has been developed convert heat taken infrared spectrum into electricity. not-too-distant future, it will an impact wide range fields, such mobile communication (5G), radar detection, higher order frequency applications. Space broadband wireless communications, optical benefit its implementation.
