Microstrip line is consist of a conducting ground,
dielectric substrate and a microstrip ...
Properties
Practical Microstrip Lines has the following Properties,
 Height is of milímetro
 Have width-to-height ratio ...
 Fringing Effect can not ignored because The
electromagnetic waves are not purely TEM in
nature but quais-TEM
Characteristics components of
Microstrip Lines
 Relative Permittivity
 Effective Dielectric
 Wavelength and Velocity Factor
 Characteristic Impedance
If w/h ratio tends to infinity then Relative permittivity
tends to relative permittivity and characteristic
impedance same...

  1. 1. Microstrip lines BY MARYAM LIAQAT TO PROF. FREDERICO D. NUNES FEDERAL UNIVERSITY OF PERNAMBUCO,(UFPE), RECIFE BRAZIL
  2. 2. Linhas Microstrip de Transmissão Microstrip line is consist of a conducting ground, dielectric substrate and a microstrip having thickness is in micrometer and height in milímetro
  3. 3. Properties Practical Microstrip Lines has the following Properties,  Height is of milímetro  Have width-to-height ratio (u=w/h) 0.1<u<10  Propagating in Z-direction
  4. 4.  Fringing Effect can not ignored because The electromagnetic waves are not purely TEM in nature but quais-TEM
  5. 5. Characteristics components of Microstrip Lines  Relative Permittivity  Effective Dielectric
  6. 6.  Wavelength and Velocity Factor  Characteristic Impedance
  7. 7. If w/h ratio tends to infinity then Relative permittivity tends to relative permittivity and characteristic impedance same as parallel plate lines have as
