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.

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
