Physicists used nano antenna for data transmission, Directional antennas convert electrical signals into radio waves and emit them in certain directions, which increases performance and reduces interference.

This principle, which is useful in radio wave technology, can also appeal to miniature light sources. After all, almost every internet-based communication uses optical light communication. for nano antenna for data transmission.

Directional light antennas can be used to exchange data between different CPU cores with little loss and with the speed of light. For antennas to work at very short wavelengths of visible light, such directional antennas must be reduced to the nanometer scale.

In the next step, physicists position the gold nanoparticles in the active element so that it touches the active element’s wire and is only one nanometer away from the other conductor. This gap is so narrow that electrons can cross it when voltage is applied using a process known as quantum tunneling, the researchers explain.

This charging movement creates vibrations with optical frequencies in the antenna, which are emitted in certain directions due to the special arrangement of the reflector and director.

The researchers were fascinated by their unusual new antenna property, which radiates light in a certain direction, even though it is very small.

Like its larger counterparts, radio antenna waves, the accuracy of the direction of the new optical antenna’s light is determined by the number of antenna elements. This allows us to build the smallest light source in the world currently operating that is able to transmit light in a particular direction, researcher said.

However, there is still much work to be done before new discoveries can be put into practice. First, physicists must work on analogs that receive light signals. Second, they need to increase efficiency and stability.
