Hey, Do can we plot the vswr chart for various frequencies in ads , say for analysing the results for a Microstrip antenna. and what are considered the good values of vswr
Hi, I want to calculate the Gain,vswr of a micro strip antenna which is designed. I wanted to see the Gain,vswr change with frequency, I'm using Layout Window to create the antenna. I would really appreciate if someone can guide me.
Hello Pulkit, Did you expect good vswr over the full 1 to 5 GHz frequency range? The answer will be definitely NO. Do some study on the behavior of thin wire dipoles or monopoles and you will see that you need a compete other approach to make something that has good vswr/return loss over 1 to 5 GHz. Regarding the center frequency (your
there is a ku_band directional couplers , the vswr is below -20,and the il<1.5dB,isolation>-24,but coupling is between -17dB~-11dB.I simulation in ads ,the coupling is -15dB~-16dB, could you tell me hou can i solution it??
Thank you vswr but i have it from nec site and i think it's not completed. In attached file the converted spice to ads, you can remark that there are no ports and even i made the ports the model did not work, could you please verify that?
Hello, It has been quite long time since I used ads for the last time! I believe you can do it very easily on ads... First, I'd like to say that as u may know, vswr is a measurement of loading effect on signal at transmission lines, or in other words, how big portion of the signal would propagate through the load. If that is what u are (...)
Hi, I want to reformulate my previous post by simple question: how to find the Q factor for a resonant antenna or a resonant Transmission Line using S parameters from ads or HFSS simulation. I know that Q is equal to fcenter/bandwith. How to calculate the bandwith, can i find this bandwidth from -10dB or vswr(S11),vswr(S21). I find (...)
Hi, How can I plot E-theta and E-phi 2D polar far-field radiation patterns in ads? I want to compare both? How can I do this in ads? What's the impact of Axial ratio, which is best low or high? How can I plot vswr vs. Frequency in ads? How can I know in ads, whether impedance is matched or not? (...)
Anyone who know how to add a vswr=2 circle in the smith chart in ads data display file?
Normaly I used vswr(S(1,1)) for vswr value reading. Can I read vswr value when I put a mark on the S11 trace without set any equation in ads ? Thanks a lot.
who can tell me how to plot constant vswr circles in ads? thank you in advance!
Hi, Constant vswr circles are actually constant gain circles. Device itself has gain that coresponds to Gmax at a given frequency. By chosing the gain smaller that Gmax (selecting a constant gain circle instead of a dot that corespond to Gmax) you are mismatching the device. The mismach is constant on a constant gain circle, so is the vswr. You
