Re: How to display current distribution on the patch in HFSS
I tried to see the current distribution on my patch antenna, but there is no way how to do it. In Help of HFSS says that HFSS/Fields/Plot Fields but there is no plot fields choice in my menu, is there any problem on my version or...
I designed a prob fed microstrip patch antenna and used Lumped port but I dont know which direction will I draw the integration line for the port? When I changed the direction (x or y axis) the results were change. could anybody help me?
What are the basic antenna parameter measurements wiht HFSS, input impedance, resonans frequency, radiation pattern, bandwidth? And, I can' t find how I measure the bandwidth of a msa in HFSS. I found the resonant frequency graphics but not any other. How can I interprit the result graphics...
I am trying to do a simulation for a msa with shorting wall. I drew it but I dont know what I need to assign on shorting wall for radiaton or ext. Could anybody hepl me for this?
coax port in hfss
I have a question for armant and all of you. How can we find the T parameter (height of the coaxial)?It changes the resonant frequency, I tried lots of times. Is there any formulas or calculations for T?
defination explain what is coax conductor
I tried to do different simulations for coaxial feed.
I assigned Pef e to the outer face of the probe, with pin, without pin, only the face of pin, the results arent very different. Now I get it from the answers, I must assigne Pef e to the outer face...
I have to design a triangular patch atenna by HFSS but I cant find how I can draw a triangle! I tried to do this from Draw/Regular Polygon and chose segments as 3, yes there was a triangle, but I couldnt change any of its specifications and position parameters.
Could anyone help me?
I would like to ask a question. How do you choose the radius of probe inner/ outer?
I see for big patches (cm dimensions) 0.7/1.6 mm but what about small antenna patches in mm dimensions? It is too big for them.
Re: between the thickness of the substrate and the radius of
I saw some simulation files and I guess they used the probe radius as half of the substrate thickness, I try like that I have better results but not the best. May be the trial and error way can help you.
I think for the first error, you must cut off a piece of ground for the probe. The cutoff part's dimension is same as the probe (not the pin)
For the second error, you will draw another circle under the probe with the same radius then you will assign a waveport on this circle.
I have no idea...
I would like to ask anotherquestion. How can we choose simulation parameters for any different type antennas?For example, while adding sweep which frequencies we can use for 2.4 GHz antennas?
I am studing a design about microstrip antenna. If it finishes, I will send it with explanations.
But now I have another problem. When I choose only one face of any object, I cant change its properties, because "Properties..." isnt active. Is there anybody who can tell how I can change?
I found some examples on the net and I try to do them in HFSS by myself. It helps me a lot while learning and practising the software. I can advise you to do like that.
