hello.. im designing frequency reconfigurable patch antenna at frequencies 2.45,5.5 and 7.5GHZ in hfss using pin diodes. i have assigned lumped rlc boundary to pin diodes.but im not getting exact frequency resonance. can anyone help me how to use pin diodes is biasing also required for pin diode??

applying T network in hfss

hiiii i am using a lumped T network in hfss now i have to place this between two microstrip lines. s1 and s2 are the series arm of the T network and p3 is the parallel arm of the T network then how i am supposed to connect this to the two tr line. i connected s1 and s3 to the conductor of the microstrip lines and (by keeping two sheets and giving

HFSS lumped port not equivalent to lumped RLC boundary condition

Hi, I have a design with 2 waveports and 1 lumped rlc surface that simulates a capacitor. I have changed the rlc surface into a lumped port to have a 3x3 Z matrix, this way I can change the values of the lumped capacitor in post processing and reduce the 3x3 matrix down to a 2x2 matrix : V1 = Z11*I1 + Z12*I2 + Z13*I3; V2 = Z21*I1 + Z22*I2

HFSS: Strange results when simulating a capacitor (RLC boundary)

I tried to make a S11 based measurement of a chip capacitor in hfss (simulated measurements) I made a 50 Ohm microstrip line of layered impedance rectangles, put a rectangular patch at the end and applied 0.55 pF capacitive boundary to it. Other side of the capacitor is shunt with another vertical rectangle with perfect conductor layered impedan

Resistor in HFSS for a Wilkinson power divider

I'm not sure exactly what you're doing, but I can explain how to use a lumped rlc boundary in hfss and set its resistance to 100Ω. Regarding the current line (for a lumped rlc boundary), you just set the starting point at one end of the resistor and the end point at the other end (touching the edge of (...)

Want help in designing 1-2 wilkinson power divider in HFSS

you need to right click on an object an assign boundary>impedance OR Lumped rlc OR Finite impedance. I have never used these options but I am sure you can find the best one for yourself with a quick google search.

lumped RLC model in hfss

Hi, lumped elements are designed like lumped ports in HFFS. First you have to create a face (rectangular, ...) between the two connection points of your lumped element. Then select the face and choose 'Assign boundary' -> 'Lumped rlc'. There you can choose the parameters (R, L, C). At the end you have to create the 'Current Flow Line' which gives

draw a plane and define it as rlc boundary condition

question on hfss lumped port

Hi Guys, I am simulating a loop antenna with hfss. Since the diameter of the loop antenna is very small, it does not resonant at the working frequency. I use the driven mode and lumped port. From Z11 I can see the input impedance is 818-158j. So I plan to add an inductor to cancel out this reactance. But how to do that in HFS

how to draw model of lumped RLC for cap in hfss

Hi All, How do i draw lumped rlc for cap? attached with file...i want to know the orientation of the cap please help...

how to add lumped capacitor in HFSS 9.0

I just want to simulate a very simple rlc resonator. It is made of copper wire and a capacitor soldered at the both ends of the wire. How can I add the capacitor in hfss. I found there is only lumped rlc boundaries in hfss which can only be added o a surface, and I really don't know how to handle it. Thanks for your (...)

a few basic questions about hfss

Hi, I have trying to make a very simple simulation on hfss but I have very little idea how to do it. I installed the program and I go through the getting started example named "antenna", however, it hadn't much helped me. What I have been trying to do is placing a inductor to the end of a 80cm wire and placing another 2cm wire to another end of

How to import a set of RLC versus frequency in HFSS?

Hi, I use Lumped rlc boundary condition but I want to know if there is any way to import a set (array) of R L and C versus frequency? I mean a s

How to set up the impendance of the RFID tag in HFSS

Hi! If I simulate the RFID tag whose impendance is R-jX, and reach to match impendance, how can I set up the port whose impendance is R+jX . The way I use is setting up the port to the R and another is seeting up rlc lumped boundary. is it correct? May someone have the example as this way? thanks ruey

simulating planar interdigital capacitors using HFSS!!

hi in general in hfss for design capacitances we have problem, but usually we can simulate capacitace with one boundary condition plane. you must first in where you want to have capacitance draw a squre plane, then select this plane and assigne LUMPED rlc boundary to it. you can simulate your real capacitance with R and (...)

RLC boundary condition in HFSS

yes, you can put it inside the computational domain (air box), I didnt see any problem. for CPW rlc termination, I suggest this structure: Regards,

Help on HFSS lumped RLC

Hello, You have an open circuit. The sheet named "resistor" has no boundary assigned to it. I suppose you ment it to be a Lumped rlc boundary. Double check your model by clicking the hfss menu and choosing "boundary Display (Solver View)". Itai

Question about Lumped boundary condition in HFSS

Hello everyone, I am designing a power divider in hfss and need to use a resistor for the same. Does the Lumped rlc boundary condition let me do something like this? I read the explanation in the tutorial and it does seem like the tutorial says that but wanted to make sure. Has anybody worked with this kind of thing before? Ananth.

How to simulate a resistor in HFSS ?

Create a 2D object (such as reactangle) and set in Lumped rlc boundary condition. notice that you must define a Current line for it.
