hi everyone,for the last one year i am working on designing a UWB antenna in cst. i have few doubts on cpw port dimensions in cst mw studio. 1. is my port dimensions to excite the cpw are correct ? if not please correct me 2. what are the details we need to consider before defining wave port dimension to excite (...)
hello frds, recently i designed conventional cpw fed UWB monopole antenna in cst, i dnt know whether my wave guide port dimensions to excite the cpw feed are correct or not. can anyone simulate the designed antenna and provide remarks.
Can anyone help me regading feeding of cpw fed antenna.
please help me by providing cpw feed port dimesnions in cst to exite the microstrip antenna
please provide the necessary design steps to design sma connector to feed cpw in cst
please help me to design sma connector for feeding cpw
I'm simulating a grounded cpw in cst, I want to apply a proper boundary condition to it? who know what is the suitable boundary condition? what envirement i shoud use in cst? note that i'm simulating a Gcpw fed Horn antenna if this effect the boundary condition of structure... tanks
hello how can I do the excitation for conductor backed cpw??? which kind of port???
Hi, I want to connect a microstrip using Copper with a Roger's 3003 substrate to a cpw with Niobium as the center conductor and ground plane and a silicon substrate. I have connected them currently using bond pads, but does anyone have any suggestion for a better way to connect. Also, when i specify the ground plane and center conductor as Ni
Ok let's try: 1) So, my first question is which feeding port is most suitable for this type of design.Discrete port or waveguide port.: It depends I think, if you have just your antenna, waveguide excitation would be correct if you use for example some microstrip or cpw as feed. In your case, I recommend a discrete
Can someone tell me how to design a microstrip antenna with a triangular patch with cpw feeding on cst??
Hi Friends Recently I have designed a EBG cell which it's reflection phase around 3.5 GHz is zero. In order to use this structure I've used a cpw antenna with resonant frequency of 3.5 GHz. The problem is I expect a resonant frequency of 3.5 GHz for whole structures (maybe with some ripple), but the resonant frequency is shifted to 4.5 GHz and som
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 use any DC Block then RF
There is a how-to page on FEKO's website on how to create a cpw feed in FEKO.
I'm now try to calculate grounded cpw impedance using cst. I added waveguide port according to tutorial section 'Wveguide Port Overview'. If the port is in boundary plane (shown in fig1), port mode shows normal QTEM mode and the calculated impedance is accurate. However, if the port is located internally, means the port is within boundary (show
Hello, I am currently trying to simulate a cpw resonator @ ~7GHz using cst microwave studio. I've attached the cst file in case people want to help. At the moment I'm not getting any good results, the S21,S11 parameters are flat, no peaks or dips. Not sure what I have done wrong in my design, the ports I defined are larger than the (...)
i am new to antenna design as my PG going on i have to work on antenna design. Currently i am working for antenna design in cst MWS software, but i dont know how to create slot on a patch over a microstip antenna. plz somebody help me for slot design. I am thankful to them.
I want to create a wave-guide port for following structure. It is 'cpw with ground' or 'grounded cpw . What should be the dimensions of wave guide port? Please see the structure below. 96793
Hello, I am simulating a cpw to CPS transition in cst using transient solver. I am not sure if I am setting the port parameters correctly. I tried two appraches:- 1. Defining multipin port and setting up potentials. (But this means I am manipulating my simulation and only getting the desired even mode whereas in reality I might have both
Dear All, I have imported a Differential trace into cst MWS, and I am using "Time Domain Solver" to get S-parameters and TDR measurements; the Problem is that we are getting wrong results.. we have used Polar software and the impedance is 100 Ohm differential.. but the TDR in cst MWS show a 3 Ohm impedance. I am new to cst MWS, it (...)
