Hi everyone, i want to design a double stub tuner by hfss . i need an example for begin design it. can everybody help me??? thanks. hadi
I'm using hfss...how shud i add a stub to my patch antenna? shud i add it on the substrate itself? also i'v to use a switch as an interface b/w patch and the stub...what are the matching considerations required? shud i "unite" the patch, switch and stub or not? plzzz help its urgent :sad:
i have designed this model but i dont know how to use stub in hfss as given in the paper.....thats why results are not accurate as i am not using stub in my design.....................can any body help me to come out this problem? thanks in advance.....
Hi guys, I'm new here. Just a quick question: One of my assignment is to simulate an open stub through a transmission line (50ohm) to a load of 155 ohm. I used my smith chart to calculate the distance and length of the stub (in terms of wavelength) but I do not fully understand how to convert those numbers to design a physical (...)
The probe length is generally chosen to be less than the height of the DRA, to avoid probe radiation. YOu might consider a stub on the other side for tuning the antenna. (Added) other side of DRA on same surface.
please help me design stub loaded helix in hfss . i,ve given the link for the geomatry of stub loaded helix please help me to design this in hfss ....thanks... [
Hi, can anybody tell me how i can make stub loaded helical antenna or how i can add stubs in helical antenna in hfss. please help me...
Hello, I am currently building a demo of a microstrip line with a tuning stub. The transmission line is terminated in a load impedance of 100-50j ohms. The microstrip line has a Z0 of 50 ohms, and the stub has a Z0 of 100 ohms. I know my designs for the microstrip lines work, but I am having trouble terminating the transmission line with the fix
Hi all, I have problem with microstrip delta stub design. I referenced some paper about radial stub, ... but can't find exact program for calculation, even wrote some maltlab m-file for it.But my results are different from others done by some author. Specially, in the paper "A NEW KIND OF RADIAL stub AND SCME APPLICATIONS"-attached (...)
Please help me in drawing radial stub using hfss. I have tried arc, polyline etc. But I want to have a radial stub with a thickness, which means it is 3D and not 2D. I need to know how to draw a 3D radial sub in hfss. Radial stub is like a slice of pizza. Please help!! It is urgent!!! Any reply will (...)
Hello All, I am trying to emulate the single stub matching network example given in Pozar's Microwave Engineering using a microstrip realization on a 14mil FR4 (dielectric constant = 4.4) board. The 50ohm thickness works out to be 0.675mm for this board. However I am not getting anywhere close to 50 ohms at the port in my hfss design. I have att
I want to matching bow tie antenna, and to minimize imaginary component i want to use stub, but i don't know how to assign stub in hfss Please help me????
I want to draw the stub Loaded Helix (SLH) in hfss, which offers a substantial size reduction over a conventional axial mode helix without sacrificing performance. I am having problems designing this helical antenna.I draw the structure,but it didn't work ,it have some errors,may be the stucture i have drawed is wrong.I don't understand,because
Hi guys, could anyone share your experience on how to draw/simulate Radial stub in hfss. Because my design is a 3-D stucture (CPW-TO-Microstrip), and i know the RS could be easy simulate just by drag the icon in ADS. But in hfss, I'm newbie. Many thanks.:D:D
can you send the structure, may be you have made a mistake in implementing the stubs
