## CST-Microwave studio- transformer simulation

Why you need to simulate power Transformer in cst? Can you explain a bit?

## CST MWS: S21 doesn't change despite separation distance

Hello all, I am trying to determine the power read at the receiving waveguide port due to the reflected power off the PEC wall from the transmitting waveguide port. The setup is 2 waveguides, stimulated with waveguide ports, slightly separated from each other and both facing a finite PEC wall in free space at a fixed separation distance. W

## Too small dissipated power in HFSS compared with CST

Good morning, Let me contextualize the problem I found with dissipated power and the way HFSS computes it. I'm working now on a model which goal is to study the power losses that a certain material introduces. To do this, I used a basic electric dipole antenna, at 2.45GHz, which is λ/2 in electrical dimensions. This antenna is placed inside

## high power handling study (cst)

Matheai young and jones (the bible) has a good chapter on high power waveguides. I would start with that.

## cst- how to look at the impedance of distance?

133561133562133563 cst- how look at the impedance of distance ? power voltage( 500V, 20A) source put into a long cooper bar then, other PCB plate sense a voltage level (according to distance 1mm~100mm) example ) when 500volt put into cooper bar, PCB plate sense 0.1V

## how to designe?? see the coupling level -CST

133353 sorry. i'm not speak english very well i designed 2 bar. i want to see coupling level i was discrete port S-parameter, Voltage, Current but not saw power level, impedance Q)1. when only one bar give 1~10 kW electric power(1~13.56Mhz) , the other bar detect power level, Voltage level, impedance. Q)2. ho

## 100 ohm resistor in Wilkinson power divider in HFSS

I do not know HFSS, (I'm a cst type). Search on "ohms per sq". The length/width and ohms per sq define the resistance. Dimensions of the resist and thermal conductivity also defines the amount of power dissipated. power dissipation may or may not be an issue to you. As a first approximation, throw an ideal lumped element resistor in (...)

## Evaluate leakage field power in CST

I'm using cst Microwave Studio to simulate a thin square cavity resonator, one face of which has a grid of holes. I want to evaluate the amount of field leakage, to relate it to the hole size. This involves quantifying the power transfer through a plane, but at this stage I do not even know how to write out the field intensity values on a specifi

## CST default power WG and SAR

Hi, I'd like to better understand cst default power for WG and for SAR calculation. I've used the default power (peak power 1W, or 0.5 RMS), but I got half values compared to a simulation (1W) done with SemCAD. Any suggestions? Many Thanks1

## [CST MWS] Simulation of helical coils for Wireless Power Transfer system in CST

Hi all, I am trying to simulate a wireless power transfer (WPT) system with two coils (transmitter and receiver). I have created a helical coil as below: 128310 My question is: Which is the suitable port for the helical coil? And how to excite this structure? Thank you so much.

## CST MWS Radiation Efficiency vs Total Efficiency

radiation eff is total emitted energy/supply energy total eff includes also the power lost due to poor VSWR (or mismatch loss).

## [CST-EMS] Coil design using copper wires

Dear All, I need to simulate a transformer using cst EMS to eddy-current and thermal loss estimation, quite similar to the following application: I designed the transformer coil with copper wire and set simulation to run (I didn't use the coil definition fro

## S-parameter graph showing straight line in CST design

Hi all, I am new in cst STUDIO SUITE. I created a model of our PCB in cst and done the simulation,but result is strange,showing a straight line. If any of the cst experts see this post,please reply. My doubt is regarding discrete port setting, for antenna excitation I used ground layer. Is it ok? Should use power layer? (...)

## how to checkin cst either my antenna is matched or not? i

Depends on your application really, with s11= -11dB, that tells you that approx 10% of input power was reflected. with the resonance at 2.35GHz, if, with the same configuration s11=-10dB, it still indicates that at 2.4GHz 10% of power reflected. Ideally, you'd try to centralise your resonant frequency at the frequency of interest, because standard

## Where to find dbm value in CST?

I only see the dBi value in the farfield plot. Yes, because only that makes sense for an antenna pattern. dBm is a measure for power. For the antenna, you decide what power you feed into the antenna. Then this power, less the internal losses in the antenna, will be radiated. The total radiated pow

## How to simulate SAR in CST MWS?

im trying to simulate SAR in cst MWS. i know i should select power loss/SAR in field monitoring to do that. but SAR value still not appearing after simulation. so i did open SAR examples in cst and create my own phantom because only head phantom available in cst and what i want is flat/tank phantom. i created my unique (...)

## matching circuit simulation with CST

Hello, I want to redesign a high power RF amplifier matching circuit to get Ideas and then modify it for our desired frequency. I'm new in electronics and especially RF. my question is, if I want to define ports for inputs matching part of the transistor, how I should do that? I've used wave guide port and since these two ports were really close

## Normalized Power Plot in CST

Hello guys, Can anyone guide me that how to plot Normalized power radiated in a specific direction in cst. let say in case of Patch antenna radiating in Z Direction.

## Temperature Calculation in CST MWS

Hi, How can we use two problem type (high frequency and thermal) simultaneously in cst? I means after simulating high frequency and calculate power losses, now I need to find temperature changes in model. I tried calculate termal losses in the high frequency type post simulation, and used that in the thermal type simulation, but i cannot change t
