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.


HOW THE ANTENNAS WORK?

CONTINUES…


Smallest antenna

• Srikanta Pal, who is with the Birla Institute

of Technology in Mesra, and his research

scholar Mrinmoy Chakraborty

• 14mmx11mm

• 10:1 bandwidth


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


Applications


MIMO Radar


Multi beam patterns


Antenna Structures


Phased Array


Radar Data Cube

• The cube is used to represent data along

some measure of interest


Mobile networks


Guess What ?.....

Olympics

Types of Handoffs

•Hard Handoff: Break-before-make

• Soft Handoff: Make-before-Break.
