Embedded or Internal Antennas. Embedded or internal antennas attach directly to the PCB and are hidden inside the product case. They're a good fit for applications where concerns about size, appearance, security or environmental issues make an external antenna impractical.

1. EMBEDDED ANTENNA
-ALANKRIT MISHRA

2. What is embedded antenna??
• It is a metallic conductor which is placed in a
dielectric medium with the dielectric constant
more than 1

3. Why do u need a dielectric medium?
• To reduce the length of the antenna ,without
changing the resonant freq,we use a dielectric
medium
• A lambda/2 dipole resonates in the same freq
when its placed in the dielectric medium
which has the length-

4. EXAMPLE
• We can use a 3.5 cm instead of a 5.8cm as the
length of dipole for a resonant freq of 2.6Mhz

5. ADVANTAGES
• Reduction in size
• Flexible design
• Durable and reliable
• Protective against environment changes
• APPLICATIONS--
• Bluetooth module
• Gsm module;global system for mobile comm.
