I had run several simulations on the meandering design
And this is the best result I can get. My expected is frequency is 925MHz and 1.8Ghz
Hmm anyone has got any suggestions to fine tune the s11 results? Many thanks!
Hi, I know its been very long but by meandering, you increase the loops of your antenna? Did the antenna increase in length as well? So far I've increased the substrate of my antenna but i didn't get a big reduce in the size. Thanks.
I would like to know as well. I am doing a 8 element antenna array. Was told that the 8 element meant 8 quasi yagi antenna. I have designed a single antenna, just need to know how to do I do about to add in the second antenna and so on. Thanks!
Hi all! Currently designing an antenna to perform dual band frequencies of 890 - 960 MHz and 1710 MHz - 1880 MHz. However regardless of the changes I've made, the best I've gotten for s11 is only the first frequency band. The second frequency band is nowhere near my requirement.
The top side...
Hi sorry to crash into this thread. I am building a dual band quasi Yagi antenna to receive GSM 900 and 1800 frequency band. Is there a way to improve the s11 parameters through physical changes made in the design of the antenna?
Hi. I have a question regarding matlab nyquist plot.
the above graph was plot using the following code.
w = {0.01, 1.2}
w =
[0.0100] [1.2000]
>> g = tf([-0.024 -0.22 1],[0.00002 0.00138 0.03529 0.4056 2.04913 4.4275 3.75 1]);
>> nyquist(g,w);
>> hold on;
>> FOPTD=tf([1],[2.52...
Hi all, I have just received a HFSS 13 software for my final year project. I'm new to this program, so is there any tutorial out there for me to follow. I do not have the user guide for this version. Thanks!
