  • Question

  • In a microstrip transmission the signal can be easily redirected by changing the centre strip.


  • Options
  • A. True
  • B. False

  • Correct Answer
  • True 

    Explanation
    A Microstrip line has a single dielectric substratc with ground plane on one side and a strip on the other face.

    Its special feature is easy access to top surface so that minor adjustments can be made after circuit fabrication.

    The high dielectric constant of the substrate reduces guide wavelength and circuit dimensions.

    A microstrip line is the most commomly used transmission structure for microwave integrated circuits.
