■ Antenna under study

The antenna radiates radio waves into space, or emits radio waves in space a receiving device. There are various antennas around you.
For example, receiving antennas for mobile phones, radios and televisions, parabolic antennas for satellite broadcasting, etc.

Among antennas, Yagi antennas and parabolic antennas it is called
a directional antenna, it can emit or receive radio waves in a specific direction. And we have a variable directional antenna
(Antenna that can control the direction of radio waves)
we are conducting research on the ESPAR antenna, which is a type of antenna.

■ Variable directional antenna

So what are the benefits of having a variable directional antenna?
For example, today, when wireless devices such as mobile phones have increased enormously please remember.
An antenna that radiates radio waves in all directions (omnidirectional antenna) when a myriad of wireless devices are communicating at the
same time, there is a problem that radio waves interfere and communication becomes impossible.

This problem is directional communication (communication by emitting radio waves only in the direction of the communication partner) I will solve it if possible. So a variable directional antenna makes this possible.
Directional communication not only solves the problem of interference,
but also (Energy) is not emitted, so it saves power.
And the ESPAR antenna has great features such as more power saving,
lower price, and easier control.
