Hi,
I have designed a voltage doubler circuit (for RFID application) using ADS. I would like to find out what is the input impedance of the circuit at different input power and frequency so that I can proceed with the design of an impedance matching network which will be placed in between a 50...
plot a sphere
hi asturia,
Can you provide me your email address? Also, I have PM you with a re-attached winrar file containing the data (in txt format). Pleae let me know whether you can open the file. Thanks.
antenna radiation pattern plotting
hi asturias,
What MATLAB function that I can use after I converted them into xyz?
Attached is my spreadsheet file. Can you explain how do you convert them into xyz and how do you plot them showing a 3D sphere? Please help.
Thanks.
phi theta antenna
Hi all,
I have obtained a dataset of an antenna containing:
1) phi (from 0 to 360 degree)
2) theta (from 0 to 180 degree)
3) magnitude at respective point (phi, theta)
May I know how to plot a 3D sphere (antenna radiation pattern) using MATLAB? Is there any other better...
gain equation of a circular patch antenna
hi mauloftin,
I still cannot understand. So, for my antenna, the co-polar direction is x-axis and cross polar direction is y-axis? Also, what does it mean when I set the polarization vector as 'X0 Y1 Z0'?
Can you explain it in your native language...
cst radiation efficiency
Hi,
I have simulated a simple probe fed circular patch antenna using CST on two different substrate - FR4 and R03010. The resonant frequency (S11) results look fine with both having resonant frequency around 867MHz.
But, I notice that the radiation efficiency /...
copolar field wikipedia
Can you attach the co and cross poalrization plot that you get? Also, in my case, how do I know whether my antenna is vertically or horizontally polarized? Please advise. Thanks.
cross polar ludwig 3 wiki
hi mauloftin,
Sorry, I cant get you for the first part. Why we have to set the polarization angle as 90 degree in my case? I can see two arrows from the 'Port' section, one is the red arrow pointing at z-axis and another is the green arrow pointing at y axis. What...
cross-polarization of antenna, vector
hi mauloftin,
I have looked at the attachment from your previous post. But, I still not quite understand. From the attachment, it stated that 'the co polarized farfield component has the same polarization as the excitation'. May i know what is the...
co polar and cross polar in cst
Hi,
Can anyone please tell me how to determine the co and cross polarization of E and H plane for a patch antenna in CST MWS?
I have designed a circular shape microstrip patch antenna lying on x-y plane and the electric field is flowing along x-axis (as...
cst open boundary
As you can see from the attached S11_all three cases.jpg result below, I got three different S11 values at one particular frequency when using three different boundary condition settings:
1) open
(1cm surrounding space for background material for xmin, xmax,ymin, ymax)
zmin...
cst background material
hi shahid/mauloftin,
Attached is the boundary condition box of my circular patch antenna. I tried both methods, using
1) open for xmin, xmax, ymin, ymax
(by setting surrounding space for the background material)
lower x distance, upper x distance = 1cm
lower y...
circular patch antenna
Hi,
May I know how can I define the correct boundary condition for a circular patch antenna which has a circular ground plane? Here are my settings:
ymin, ymax= open
xmin, xmax = open
zmin = Et=0, zmax = open (added)
After setting up the boundary conditions, a boundary...
Hi,
I would like to design a circular patch antenna with tilted radiation beam capability for my project. Is there any recommended techniques that I can use? As far as I know, the conventional patch antenna normally have the broadside radiation pattern (maximum radiation normal to the patch...
cst vertical polarisation
Hi,
May I know how to determine the simulated antenna in CST whether it is horizontal or vertical polarization, LHCP or RHCP ?
Thanks.
