here is the coplanar waveguide impedance calculator. you can calculate dimenstion of your coplanar waveguide using below link. it cannot be monopole antenna. is there any groud plane underneath the antenna?
Dear All, At the risk of annoying some of you here for posting, most probably, trivial questions on the HFSS simulation I am trying to carry out. I've scourged through the HFSS documentation and the two posts in the forum related to cpw+HFSS. I came out even more confused than before. Here I go: I'm trying to calculate the resonance frequency
Hi I am trying to simulate a simple cpw in ADS momentum. I have used the differential port setup as shown in the attached image. I have also attached my substrate configuration. The simulation is giving me the following warnings: WARNING S-parameter results show unphysical behavior for certain frequencies. Cause : - inaccurate (high freq
Split Ring Resonator (at 20 GHz) loaded with cpw (Coplanar waveguide) with pitch size (of GSG probe) 0.15 mm! 50 Ohm impedance of cpw was matched, but after loading SRR no resonance occurred. S11 and S21 curves are appearing totally flat. I loaded CSRR also, and changed different parameters but it seems coupling is not occurring (one pos
for designing a novel cpw feed fractal antenna for UWB,, they have chosen coplanar waveguide feed... is there any possibility of using probe feed??? what are all the advantages and disadvantages of using this probe feed for designing a novel probe feed fractal antenna for UWB???? rectify my doubt as earlier as possible
Hi! Greetings! I am used to generate mictrostrip to layout and then export to gerber in ADS. However, I am first time dealing with cpwG lines. I can see cpwG converted in the layout with center conductor (line width W) and thin ground lines at distance (Gap=G) apart. I can see the same once I export the layout to gerber. However my doubt is
Dear colleagues Please pardon me for a lack of education, but I can not figure out how to realize a tapered transition between completely different coplanar waveguide circuits with different input impedances. Specifically, I have a ~40 Ohm cpw input on high-ε ceramic substrate (ε>10). And a 50Ohm coax connector (SMA or K) which I at
Hello, I am using Driven Terminal for my simulation with some 50Ohm cpw waveguide. On getting the results, I want to simulate for the given power in dBm, how much current I will end up running through some sections. However in Driven Terminal the excitation is in terms of incident voltage. May I know if I should take this voltage as Vpp, Vr
I am designing meander antenna in ADS for f0=95MHZ. I would like to know how to define the coplanar waveguide (cpw) port for structure. Also for solver setup if i m simulating my structure from 50 to 200 MHz range then what should be the appropriate mesh frequency and number of segments per wavelength. Also the value of Nmax in frequency definition
I?m simulation a Grounded cpw in HFSS v13 and getting invalid results near 15GHz. 109384 NOTE: Solid lines are simulation results, dotted lines are measured results in the lab. I assigned waveport width to 4xLineWidth, waveport height to 4xDielectricHeight Simulation specifies "NOT CONVERGED" Any suggestions are
hi i'm very new in HFSS? Is there a tutorial explaining the design and implementation of tunable serial RF-MEMS capacitor on coplanar waveguide (cpw) using HFSS or ANSYS? step by step??
Dear all, I am designing a Coplanar waveguide feed for my printed LPDA antenna. I need some help about design parameter and calculation that need to be followed for cpw design on patch antenna. The feedline width of the LPDA is 1mm. can cpw be implemented on this feed width? Regards
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
I am using a coplanar waveguide (cpw) without back grounded plane, which kind of port is better? I have tried waveports, but observing asymmetric electric field using HFSS in the perpendicular direction (z) of the cpw board (in x-y plane). Is lumped ports will help me to get symmetric electric field?
Hello. I'm using free saturn PCB toolkit to determine characteristic impedance of coplanar waveguide. But I get strange results. In my opinion the impedance of coplanar waveguide should match the impedance of microstrip line when distance between GND on top and line goes to ∞ and the rest of distances are the same. But the calculator say'
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
Discrete ports are not unsuitable for waveguideS like cpw. That's why you should use a waveguide port. From the point of definition of a waveguide port, it makes no sense to placed it somewhere inside the structure. Because how you want to excite your real cpw inside? One reason for the error could be: If (...)
Hi , first of all , u must change your units to nm , then your waveguide ports have improper range , u should change it , and after that u can run it , but after some seconds , u will get error and solver had to stop , i attached a picture of problem , that u can see , the problem is about background material, try to find the problem , i haven'
I look for some tutorials for cpw design with Q3D extractor. can somebody tell me how to excite Coplanar waveguide with Q3D extractor?
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
