hfss 10 full book.zip
Thank you for your replies,
I tried to simulate the FSS by using plane wave excitation. I defined two cut planes at a distance λ/4 approximately from the source. One of the cutplanes is above the FSS structure and the other beneath it, in order to calculate the reflection...
hfss fss project
I have also thought of plane wave excitation, but how will I derive the s parameters with such an excitation? In fact, what I want is the reflection and transmission coefficient.
hfss full book v10
Hello,
I am trying to simulate a Frequency selective surface (dielectric + substrate) with HFSS. The structure is periodic in x and y axis. I want to derive s11 and s21 parameters. I use two virtual boxes (air) above and below the structure. I assign the waveports at the...
hfss evanescent
Dear Loucy,
thank you for your reply. I had tried to include a waveport in a structure, but a warning appears:"a port must have a non-existent material on one side". Only a lumped-port can be used in a structure. Do you think it would be appropriate? How can I apply a metal...
Hello, again. I checked about Q and VSWR and it is VSWR=(1+Γabs)/(1-Γabs) where Γabs is the absolute value for Γ(reflection coefficient). Concerning Q, it is Q=(stored energy)/(consumed energy)=X/R, where X,R the imaginatory and real part of impedance Z. It is also: Q=fo/BW, where fo stands for...
+ hfss waveguide antenna
Dear Loucy,
I just read your reply. In order to find the leakage and phase constant, I considered the sructure as a transmission line section and I defined the ABCD parameters which are related to the S parameters and the characteristic impedances Zo1, Zo2 (at each...
I think MP is the magnitude and phase of the constant Γ (reflection coefficient). RX represents the real and imaginary part of the impedance Z and GB represents the real and imaginary part of 1/Z. Concerning the Q and VSWR, I don't remember exactly, I have to look it up in my books first, and...
calculation of phase constant from abcd parameter
Hello again. Thank you all for your replies. I post you the antenna structure in order to get a better idea of what it is all about (leaky-wave antenna geometry.rar). The red surfaces is where the aperture is supposed to be (the only reason why...
virtual object hfss
At first, I want to thank you for your interest. In order that the leaky waveguide antenna works, the rectangular waveguide at the bottom is fed in its dominant mode.
leaky hfss
Hello! I am an HFSS v9.1 user and I face many problems. I have to simulate a leaky-wave antenna which consists of a rectangular waveguide and a stub waveguide wiht a smaller length above it. I have designed the geometry in terms of boxes united together and two tapers that connect...
how do we design horn antenna with hfss software
Geia sou! Ellinida eimai! Ego na deis ti provlimata eho me to HFSS... An boro na voithiso, efharistos.
ansoft hfss horn antenna
If you are using HFSS8.5 you must draw the horn antenna, assign a perfectH boundary to the apperture of the antenna, draw a box which will include the aperture and a small part of the horn antenna, copy the horn antenna and paste it, then substract the copy out of the...
The leaky-wave antenna I have to design consists of an open wave-guide. Do I use the PerfectH boundary condition for the aperture of the wave-guide in this version of HFSS? Please help, my results are disappointing!
