A nantenna is a type of antenna that is used in nano scale applications. Nano scale applications are those where the dimensions are on the order of nanometers, or one billionth of a meter. Nantennas are designed to operate at specific frequencies, and are used to communicate with other nano scale devices.
Some of the emerging trends in Nantenna include the use of nanomaterials for improved performance, the development of miniaturized antennas, and the use of metamaterials for novel applications.
