Metamaterial characteristics- 6.7.24

Metamaterial- Wave propagation

Negative permittivity and permeability 

To enhance efficiency 

It can be done using L and C

F=1/2pie(root LC)

No specific formula to vary the L and C in the design.But the optimization can be done by using optimetrics.

Metamaterial has the ability to enhance efficiency and wave propagation in specific direction.

Increase the bandwidth of the radiation in the antenna.

Cost can be reduced by adding more sensitivity

Use optimetrics to get required Frequency in HFSS


7/8/24

In DC We say it as Resistance 

In AC W say it as Impedance 




Transmission Lines:

Waveguides 

coaxial cable 




Types of Antenna array : 

Planar Antenna array 

Circular Antenna array

Linear Antenna array

In Antenna to connect more antennas that is arrays antenna the power divider circuit is used.

Why arrays Antenna?

To increase the directivity 

Directivity is proportionally to the gain.To increase the gain....



Impedance matching 

Input impedance should match the output Impedance .

If output Impedance does not match with input impedance then we need to use stub matching where we use inductance 


Leaned about Analog IC Design and RF IC Design 

RF IC Design - transmission line
