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 .
Embedded Plus Solutions
Smart Antenna
• The antennas convert radio frequency
electrical current into an electromagnetic
wave.

History of Radar
• Bats use a basic form of radar
• They send sound waves that reflect off of
an object just as electric radar systems do
