hello I am kind of new in ads to design cpw filter. Can anyone send me a link or website which has steps of designing? my design is ring resonator, so I want to know how to define a ground?
Hello, I am simulating on momentum/ads 2012 a cpw transmission line with finite ground planes. I am wondering if my substrate is well defined. I selected : - for the top layer: strip layer (I define then two ports connected to the conductor and I associate to them their 4 ground ports (2 for each one)) - for the conduc
Hello I am trying to find the best dimensions for a cpw line by momentum simulations in the frequency bandwidth MHz. I did some simulations, I found a |S11| around -50dB for these dimensions: - W=3 mm, G=0.5 mm and ground plane 6 mm. But this is the case of a 10cm line. When I increase the length to 40cm, a peak appears at 250
Hi , I have designed the output matching with cpwG(cpw with ground) line and L,C component. 126735 126736 126737 126738 But the result of EM-cosimulation looks strange and different from the result of schematic. (S(37,37) is for schematic, S(39,39

Hello, I am simulating a quasi-yagi cpw fed antenna on ads. The results do not match with the results as given on the research paper. The research paper did that on HFSS. Can anyone help me in this problem? The points to note: (1) I tried cpw feeding with P1 + and P2 & P3 -ve wrt P1. So the two right & left blocks are assumed to be (...)
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
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 (...)
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
please help me. how can I set w=? l=? between devices for 50 ohm in microsripe line or cpw line? pcb board is rogers ro4003c and th=.8mm
Respected all Can anybody help me out that how to apply ports in ads 2011 for FEM analysis of a cpw line. The previous version used a different method of making ports as ground reference but ads2011 does not have the facility to do so. Please refer to the image shown. I want the central line to be signal and side lines to be ground refer

Hi everyone, I have just started working in ads.I have designed cpw fed patch antenna but i am getting different frequency response of this structure in ads compared to IE3D.If anyone knows how to work with ports (ground reference for two ground plane for a reference pin for central conductor),please help me with ports assignment. Thanks
Hi everyone, I am trying to design a cpw fed patch antenna in ads.I need help with port assignment for central feed line and two ground plane.If someone is working on cpw fed antenna design in ads please let me know about it.I tried searching for tutorials on cpw fed antenna design but couldn't find (...)
Hi there: I am trying to figure out which is the best way of simulating a CBcpw (conductor backed cpw) in Mometum ads 2009. I am using a GaAs substrate (E_r=12.9, loss tg=0.006 and h=100um) as dielectric. I am trying to simulate high frequency structures (up to 300GHz). I have tried simulating various ways: 1. defining slot (...)
using a circuit simulator will not take into account the effects of the transitions between different transmission line types. As far as the solver is concerned whether it's cpw or microstrip it sees 50 ohms (assuming they both have correct dimensions). Ground in a circuit solver is ideal. A 2.5D solver like sonnet would take it into account.
Hi I am trying to simulate CB-cpw on ads momentum. I am a bit worried about the ground port definition in momentum. Any clue? Thanks
To have a ground "electrically" equivalent to infinite in ungrounded cpw, you should take the width of the ground 10 times the width of the signal trace.
Hi,all! I am new here. I am trying to design a cpw-feed meander line antenna in HFSS. I am now simulating cpw line. Does cpw has resonant frequency? I use TX-line to design the parameters of cpw. However, when I simulate, it does not resonate at my designed frequency(433MHz), but at about 10GHz. Could anyone help me how to (...)
