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
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.
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
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.
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
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.
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 (...)
I have designed a fully parameterized 2x2 microstrip patch array using Antenna Magus 5.1 Pro and estimated performance successfully. But now I want to export the antenna to cst MWS using its 'export mode'. But the dialogue box is showing "No models available to export" and I've posted the screenshot here. What am I doing
Hi, first post here and in need of some help with cst microwave studio if possible.... I've been using cst MWS for around a year now, mostly to design RF networks and patch antennas. I've been doing lots of parameter sweeps as a result of the antenna modelling side of things although I've been tempted to (...)
Hi I am working on destining a 2:1 three stage UWB Wilkinson equal power divider for the frequency range (2-7)GHz using cst microwave studio with 50 ohm input and output impedance. The design is attached and the S parameter also.
Hello everyone I design rf and high speed multilayer PCBs up to 12 layer....I want to simulate pcb with awr microwave office(axiem maybe) and cst PCB studio. I need high performance computer called workstation but I dont know how to define right processor(intel xeon or ???) right graphical card(quadro or tesla or (...)
I am implementing a simple rectangular wave guide on cst microwave studio to operate on the X-band . Does anyone have idea which type of port I have to use as I am using wave guide port and it doesn't work ? and how can I choose the mode? Thanks in advance
Hello All, In cst MWS, I'm using a square pulse, current signal as an excitation signal sent from design studio to microwave studio using the co-simulation feature. I am interested in the transient behavior of a wide-band antenna after receiving such a square pulse. I was hoping to see a damped (...)
I have used cst microwave studio. You can also use FEKO and HFSS but, personally, I don't have an idea about the latter two as I have not used them.
Hi Everyone, Could someone please help me with plotting the near field patterns in cst MWS, I know that farfield patterns can be achieved by using the field monitors but I am not sure if there is such a procedure for near field patterns. Bests
I am using cst microwave studio for Frequency Selective Surface (FSS) design. In the unit cell simulation setup i can change only the incidence angle. The solver generates output only for TE and TM polarization. But how could i simulate for polarization angles other than 0 or 90 Degree. (Ex: I want the Tx,Rx response for (...)
I want to simulate (and design) an antenna for 2.4GHz Active RFID in cst microwave studio. There is a button cell near the antenna. Most area of the outer case is anode, that is, the power, not the ground. So I wonder how to model it in simulation software. Is it OK to simply create a metal cylinder? Or the battery is (...)
Hello all I am trying to design a Bias T using CPW transmission lines in cst microwave studio. I am confused with the DC blocking. Please have a look at the attachment. I am using quarter wavelength coupled lines for blocking DC but on simulation the RF DC isolation gets worse on adding this DC block. If I do not (...)
any one know what is a differance btw e plane and h plane pattern in cst and how i can plot these two pattern with cst
please ,,,, How to define ports when integrating cst design studio with cst microwave studio? or, can any one help me to design the circuit as below :
