How to Simulate SMD Resistor in CST




How to Simulate SMD Resistor in CST

SMD Resistor

SMD Resistor with Tin


How to simulate:

1.      Draw the structure above and assign the material of each part

2.      For Ohm-Sheet you should choose the material by:



R is the Resistor that you want to simulate and w, L is shown in the above picture. Consider a good mesh size in this area.
In this the simulation we put a 50-ohm impedance between the 50-ohm microstrip line and the GND (Ground Plane is made by a boundary condition)

SMD Resistor Return Loss


As seen S11 decreased by reducing the frequency. Because in low frequencies the SMD is very small in comparison of wavelength and the SMD component is near to lumped element (ideal element).

How to design Branch Line Coupler As seen in figures blow Branch Line coupler has four ports. notice the impedance and length of each line. Schematic of Branch line coupler S-parameter matrix of Branch Line Coupler: Branch line coupler S parameter Matrix Result of Branch Line Coupler How to Design 1.      consider your own substrate board 2.      calculate the  width  and  length  of each line by CST Line Impedance Calculator or calculate by yourself 3.      consider that the width and length of the quarter wavelength is not exactly the ideal in the simulation, But the values of CST Line Calculator are a good approximation for the start of the simulation 4.      sweep these values to get the best results ( width  and  length  of each line) ADS Results CST Results CST Results CST Results Video Tutorial:  https://youtu.be/UW2Z1UWdl-c Ramian19@gmail.com Hossein Rajabloo
