What is waveguide port in CST?
As mentioned above though, CST will only let you do a waveguide port if you define either the magnetic or electric field tangent to a particular boundary as 0 (or have a PEC or PMC for a boundary). You cannot do all open boundary conditions with a waveguide port excitation.
What is a waveguide port?
Waveguide ports represent a special kind of boundary condition of the calculation domain, enabling the stimulation as well as the absorption of energy. This kind of port simulates an infinitely long waveguide connected to the structure.
What is the difference between waveguide port and discrete port in CST?
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. Discrete port is more faster in simulation than wave guide port. d. Wave guide are more accurate for s parameter calculation while discrete port are better for far field calculations.
What is the use of waveguide?
Waveguides are used to direct and propagate Electromagnetic waves from one point to another. They are generally used to transmit high frequency waves such as Microwaves, Radio waves, Infrared waves etc. For low frequency waves which are less than 1 MHz, parallel transmission lines or co-axial cables are used.
Is inhomogeneously filled within the first 3 mesh cells?
Advanced Member level 2. ort “1” is inhomogeneously filled within the first 3 mesh cells. HELP!! It is related to mesh density because if you would further increase your density, cst can use more than 2 cells in your coax adapter and it would work.
How is Port extension coefficient calculated?
You can simply go to the menu “Macro”, then “Solver”, then “Ports” and finally “Calculate port extension coefficient”. 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.
What is a discrete port?
Discrete ports are mainly used to simulate lumped element sources inside the calculation domain. These ports are a good approximation for the source in the feeding point of antennas when calculating farfields. In some cases, these ports may also be used to terminate coaxial cables or microstrip lines.
What do u mean by waveguide?
: a device (such as a duct, coaxial cable, or glass fiber) designed to confine and direct the propagation of electromagnetic waves (such as light) especially : a metal tube for channeling ultrahigh-frequency waves.
How do I change mesh in CST?
u can change from home page of CST go to Mesh tool then global properties then increase the (Near of model).
Which port is used for dipole antenna design?
The half-wavelength dipole antenna operating at 1 GHz can be modeled in CST Studio Suite® as two cylinders separated by a small gap as shown in Fig….The Model.
| Parameter | Value | Description |
|---|---|---|
| L | 135.6mm | Dipole length |
| Gap | 20 mm | Feeding gap of the antenna |
| D | 5mm | Diameter of the conductor |
| Z0 | 73Ω | Port impedance |
