yup the same antenna...
ok sir i understand...so the concept is i actually measure the reflected signal power right? it is not same with s11 (neither magnitude nor phase) parameter right?
So sir, i would like to know if i can measure that radiated power using VNA? or vna only capable to...
I have a reflectarray antenna, which function as a reflector.
I measure that antenna in chamber using signal generator (as transmit signal source) and spectrum analyzer (to receive reflected signal).
Does that mean i measure S21 since i use two different terminal/port?
And why the data plot...
Hi,
Please can someone guide me how to assign the port for the offset feed horn?
For the focus feed horn, we have the aligned feeding towards our antenna but if we need to make it offset, we need to tilt it so it makes the feeding no longer align with the antenna.
So my friend told me to use...
I figured out that we need to use OriginLab to plot the graph.
But...can someone look at my contour plot...why it has red line instead of circle for the highest gain value..?
I have attached here the 3D polar plot (from hfss) with its contour graph (from originlab)
Pleaseee someone help me...
I have 3D polar plot graph for my gain...how can I transform the graph to see it as a contour graph in HFSS? The graph axis should be like below:
y-axis = elevation
x-axis = azimuth
Please help.
Thank you.
Hi all,
Can any1 help me on traxmaker drawing for reflectarray element?
For example, i want to cut 0.2mm at 90deg and 270deg. I use pad to draw the ring element but don't know what tools to be used for cutting.
