Mobile Communication

•People live all over the world can

connect with one another through

Embedded Plus Solutions

Why we use Antenna

• In recent years, There is a

development in wireless access

technology.

•Due to the NUMBER OF USERS

THE ANTENNAS

are introduced .

Smart Antenna

• The antennas convert radio frequency

electrical current into an electromagnetic

wave.
