Hello
As a part of design I have made a polyline. And I want to keep it at (x,y,z)=(p,q,-r) so using move command I will set anchor point as a (0,0,0) and (dX,dY,dZ)=(p,q,-r). And it will move from the starting point of a polyline. I mean where I started to draw polyline whatever was my...
Dear FvM
I am just looking for an answer that what I am doing is right or wrong?if it is right than why is it and if it is wrong than what i can do to improve my results? it looks like it is wrong so from experts like you i need some kind of guidance which can help me to solve problem. I am...
Hello all
I am trying to design a dipole antenna using HFSS. In my design i plotted a graph for input impedance Vs frequency and it seems that instead of somewhere close to 73 ohms i am getting it to 117 ohms which is way to off.so can anybody take a look and tell me what is wrong with a...
Hey streamlet
from the attached file can you say that is it correct or not?instead of 73 ohms i am getting around 117 ohms in the plot. so can you give some advise? or any opinion on that?
Hey Volker_muehlahaus
Can you just take a look and tell me that for dipole is it correct?i was hoping to get impedance somewhere nearer to 73 but i am getting nearer to 117-118, so why is it so? is it even possible? any idea or suggestion will be grateful.
Hello FvM
I was going on a wrong track and with the help of your guidance i realized that, now i have step down and i am just attaching a file which contains output of a dipole antenna only, nothing else.center frequency is set to 300MHz. If it is correct than only it is advisable to step...
Hello FvM
Here I am attaching pdf which contains tabular plot for same ellipse.pdf graph. according to it Re(z) is very close to zero but now zero. but still resultant impedance is very close to 0 so is it a good thing or not?my lumped port is set for 75 ohms so does it mean that there is...
Actually in ellipse.pdf if you open it in HFSS than straight line at 0 indicates Re(z) for all the distance, only imaginary value of impedance is varying, I tried to attach original HFSS file but system don't allow me to attach with HFSS extension.
Here in the attachment i have kept figure with the zoom.
what does "In the first, the important real impedance part representing the radiation resistance is missing." mean?
Thanks for your reply.
I am using HFSS 13 and yes center frequency is 88 Mhz but i have plot Z11 Vs frequency not S11. i guess Z11 will give me the input impedance not the S11, if i am wrong than please guide me.and if i am right than what should i interpret form that?
Thanks FvM
In both the figure X axis shows the frequency and Y axis shows Z11 of real and imaginary. almost flat line at 0 shows Real part and other buch of lines shows imaginary part at the different distance between antenna and parasitic element.
For the other figure i don't have access to...
Hello all
In the attachment i have attached a pdf which contains the graph of input impedance Vs frequency of a dipole antenna and ellipse shape parasitic element at a different distance between antenna and parasitic element, I basically want to know that what can be interpreted from the...
Hello all
I am working on a design of antenna and different shapes of parasitic element, and as a part of that i want to design I-shape parasitic element. but the one more requirement is that i want to change the distant between antenna and I shape element in a same file.Like my antenna is on...
