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 (...)

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 (...)

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 (...)

Hi, I am working on a tunable/reconfigurable PIFA at 2GHz and 2.45GHz using cst microwave studio software. Is there anybody here that can help me with files or thesis related to this antenna design? As for now, I am having some difficulties in making the reflection coefficient falls below -10dB at the desired frequencies.
Hi, I have build a circular waveguide with tapered extruded sections at each ends of the waveguide. I have also successfully simulated the design with 1 or 2 warnings and got results as well, but not quite sure of un
I tried to design a DRA antenna in cst MWS whose file is attached along with.But I am not getting desired S parameters which may be because of ambiguity in applying ports to the antenna.I am applying a waveguide port at the feed line which is feeding the slot. I am supposed to generate TE mode in that waveguide port.Discrete port is applied at the
is this possible to design a BPF in cst microwave studio itself? Like all EM simulators, it is an analysis tool to calculate the response of an existing layout. Like all EM simulators, it does not help you to create (synthesize) the layout. If you need help with filter design/synthesis, t
