Transcribed: Using substrate of ɛr=3.38, h=1.6, find the width of microstrip sections that implement the above circuits as well as the corresponding length of quarter wavelength sections.

Answer

Given, 

εr = 3.38 h = 1.6

The width of the microstrip substrate is ,

w = 12frμ0ε02εr+1 = v02fr2εr+1 

Velocity of light in space,

 v0 = 3×108 m/s let resonant frequency , fr = 5Hz 

w = v02fr2εr+1= 3×1082×5×10923.38+1 = 0.02027 m= 2.027 cm ie., w = 2.027 cm   

 

Then the corresponding length is 

L 0.47 λ0εr0.47 v0frεrie., L = 0.47 3×1085×1093.38=0.01533 m =1.533 cm  

 Therefore the corresponding length is 1.533 cm
