What is the difference between waveguide port and discrete port in CST? Wave guide are more accurate for s parameter calculation while discrete port are better for far field calculations. Wave guide and discrete port are the two main ports used in CST for the absorption and simulation of power for any device under test. What is the difference between waveguide port and discrete port? You can enter the parameters of your substrate and the trace width then CST will give you the size of the port you have to use, including a schematic that will explain you how to create your port. You can simply go to the menu “Macro”, then “Solver”, then “Ports” and finally “Calculate port extension coefficient”. In a coplanar waveguide-fed microstrip antenna, the antenna and coplanar line are placed on the opposite sides of the same dielectric substrate and the coupling from the coplanar line to microstrip antenna is accomplished via a slot in the ground plane connected directly to the end of the coplanar line. What is coplanar waveguide feeding technique? In the case of CPW where you have the ground on the same plane as the transmission line, a common ground and transmission line is used to define port as shown in fig. This kind of port simulates an infinitely long waveguide connected to the structure.Ĭo-planar ports are used specifically for co planar waveguide (CPW) circuits. Waveguide ports represent a special kind of boundary condition of the calculation domain, enabling the stimulation as well as the absorption of energy. 7 How to model the coplanar waveguide in Excel?.
