## [CST] Gain and Efficiency simulation with antenna matching component

hi all, im simulating an antenna in cst microwave studio. i have added matching component in cst design studio and the S11 is good. i want to simulate antenna efficiency and gain with this matching components. how do i do that? thanks

## 4 port rectangular waveguide switch

Hi, Can anyone help me design a 4 port rectangular waveguide switch in cst microwave studio?There is no example given in the tutorial.I tried designing it,but the s-parameters are showing erroneous results.

## Scaling of EM Fields in CST MWS via circuit simulation.

I have simulated a 3D EM model in cst (HFSS). Then in the design studio, I have developed a tuning circuit which is fed to EM model. cst then calculates the fields in EM model according to this excitation from the design studio. A similar operation can be done with HFSS and Nexxim (by using (...)

## CST MWS: Antenna Calculation difference in E-farfield pattern values

Hi everyone, I am currently developing software in MATLAB to calculate the S21 parameter based on the E-farfield pattern simulated in cst. However, MATLAB doesn't calculate the correct S21 values from these farfield patterns. I read something about Antenna Calculation in the cst design studio handbook (p.93). When (...)

## Differential feeding for a triangular Bow Tie Antenna in CST Studio Suite

Hi everyone, I am new to cst studio Suite and I am trying to design a triangular Bow Tie Antenna. The triangles are made of copper and they are placed on FR-4 material. My problem is that I don't know how to design the differential feeding for the antenna. Can I use two discrete ports or do I have to design (...)

## CST STUDIO: Farfield plot's center is not where the port is?

I'm new to cst studio and I'm trying two simulate two antennas together. What I want to know is when I add excitation to one antenna, how strong would the signal be when it is received by another signal. The two antennas are both dipole antennas and are designed to be at frequency 2.4GHz and 2.5GHz. I put one discrete port in one of (...)

## CST in batch mode opens GUI

I am running the following line "C:\Program Files (x86)\cst studio SUITE 2016\cst design ENVIRONMENT.exe" -m C:\Temp\macro.bas where macro.bas is Sub Main OpenFile("C:\Temp\Downloads.cst") StoreParameter "offset", 1 Rebuild() Solver.Start End Sub cst opens (...)

## Designing "horizontal V antenna" with CST Microwave studio

Hi, The shape of a horizontal V antenna is this: 130290 I have to design a horizontal V antenna to compute impedance (R + jX ) of V antenna above ground. Which will result in the following figure after the simulation: 130291 This figure is in book "Antenna Theory Analysis and design 3r

## How to design SMA Connector Design in HFSS/ CST MW studio?

Any one designed and simulated SMA connector. If any one designed please send their model i will be thankful to them.

## Cst antenna waveport error

Dear sir, I want to find out the group delay of my uwb antenna i am getting error while assigning the second wave port in cst MW studio 2015. Please give me the required solution to my problem to find the group delay. I am attaching my design here. If possible can you send your model to me. 129270 Thanking you.

## [moved] Installing new material but frequency dependent properties

Dear all I am design an antenna which is work in UWB frequency range.I want use this antenna for body.can any one tell me how Installing new material with frequency dependent properties.i use cst studio 2014.for example when i want to create phantom model which frequency considered? I need more help thanks

## Axial ratio optimization in cst

Hi everyone. I am new person in antenna design sector. I need to optimize axial ration of an antenna with cst studio. can anyone let me know the process. that will be so much hlepful for me.

## Designing Printed Log-periodic dipole array in CST

Hello. I have this problem. I have thesis Log-periodic antenna. Now a must design this antenna in cst studio. But i dont have idea how. :cry: I have all calculations for construction of this antenna (Log-periodic). For all calculations i use book Antenna Theory by Balanis. My teacher recommend me this perfect book. This antenna will be (...)

## diffrence between various cst solvers

what are the different solvers used in cst MWS(microwave studio). if i want to design antenna(1-5 ghz) using these then which solvers will be needed. any specifications in these solvers.

## 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? (...)

## CST Design Studio Voltage Signal Source

Hello, I am currently trying to simulate a full wave bridge rectifier in the design studio portion in cst to use with an antenna. First my professor wants me to simulate the rectifier in cst using the signal voltage source and I want to set the frequency of the source to 2.45 GHz, but I cannot figure out how to change (...)

## CST Microwave Studio. Collimator modelling.

Colleagues, I met with the problem while trying to calculate amplitude distribution on planar surface at a certain distance (200-400 wavelength) from the collimator aperture. The problem is that the calculation process reach?s RAM limit (16 GB) and terminates with error when I use time domain solver. Obviously, it happens because of large d

## DC-voltage sweep @CST Design Studio

Hey, i would like to know how i can make a DC-voltage-sweep in cst design studio with Current. I have a simple circuit consist of a diode and i want to see what is the current across the diode with different values of dc voltage. Does anyone knows, how can i do that ? Many thanks !!!

## lumped resistor in CST Microwave Studio

Hi All, I try to design SRR antenna with additional capacitance in between gap so that it will match my 50 ohm input impedance.But it doesn't show any effect of S11 when i change the value of capacitance. Can anyone help me on this matter.Here I'm attaching the cst 2014 file. Thank you in advance.

## Biconical antenna - CST model (Antenna Magus)

Hello, I'm quite new to cst Microwave studio and I'm not sure if my model of biconical antenna is correct because I got strange simulation results (VSWR). I noticed on internet that there is a model of EMC wire biconical antenna in Antenna Magus design software (which I dont' own). I would be very grateful if u guys could send me (...)
