Hi...
I'm doing multistage rectifier....
During schematic simulation...measured output current (I) and voltage (V) are good...(all the impedance/resistance value are remain the same for different input power). However, the same circuit (same component but now with the layout)...the measured...
an easy way
click on the plotted graph, then click File --> export --> write data....into ACII
then u will have the data...can be used to plot using any software
regards
Hi....i want to know the right setting of axial ratio in CST...
i have seen different setting for axial ratio from different papers...so, it make me confuse which one is the right one...:roll:
1) theta 90, min value
2) theta 0,phi 90
(both 2 pictures are from template based processing...
Hi...
i'm doing rectifier for GHz application...my problem is finding suitable capacitor for the rectifier circuit...Previously, i used through hole ceramic capacitor and its operates well for frequency below than 1GHz, however for higher frequency the results are not ok.
i'm looking for...
Hi...i'm working on rectifier circuit using ADS....i got a good results in schematic simulation..however when i convert the circuit to layout...my result decreased about 1V and fluctuated/ have a big ripple (+-4V ripple). I would like to ask any suggestion to improve/optimize my result so that i...
Hi...if u are using software...u can try to do S-parameter simulation/calculation...where u can find the load impedance using S11 (by plotting the smith chart)
Hi....
i would like to make a slot with angle 45degree, but i do not know how to define it with angle 45degree.
i try to do by using Transform-> rotate, but then i dont know how...
also try using poligon, but then i need to carefully calculate each point of the object manually. is there any way...
Hi
From what u worte, my port definition ok...
yup, the antenna look simple...How, this is part of my miniproject..so i have to present simulation n measurement result..
i will try to find this software...hopefully there will be free version for student usage...or at least trial...
Many...
Hi Ferdows....
1. thanks for the attachment
2. Currently, i only have CST software...thats the only choice i have...didn't have HFSS and never have experience with it
3. hmm...port definition? i'm using microstrip line feed which i define port at the end of the line( cover Ground thickness...
Hi..tq for the reply...
FYI...my antenna resonates at 3 different freq at 1.126 GHz (-24.4dB, BW 40MHz), 2.45 GHz (-20.96dB, BW 73 MHz) and at 2.9 GHz (-21dB, BW 91 MHz). I think this result is good enough, but due to its low efficiency..i'm afraid i would not get a good measurement result of...
Hi...
i'm doing project about shorted patch by using CST. what i did was, i design square patch antenna and i make a hole at one part of the patch, which i put a pin with radius of 0.5mm (connected patch to ground). i got a good result in simulation (dual frequency RL <-10dB) , but the...
design of inset feed line
Hi rshirodk...
hmm.. confused with the equation below to calculate size inset feed of patch?
for equation above W*L =1.25, W will be >>L, am i right?
i also wanna know how calculate the gap (slot for inset feed) between feed and patch
TQVM :D
