Hi..i m working on a pentagon shaped patch antenna for 4-12 GHz frequency range with a design frequency of 7.5 GHz. I m trying to use coaxial probe feed. I found good results at one location on patch but the patch is not resonating at designed frequency. How do i optimize the probe feed to obtain resonance at designed frequency?
plz.. help me to construct a stacked microstrip patch antenna in zeland ie3d.... how to joint a single feed to both the antennas in stacked configuration both in software as well as hardware? and please tell me the procedure how to do probe feeding to yeald at maximum gain.
the circular match antenna raidus is taken as 27.7mm While modelling the coaxial probe feed to patch , the inner and outer diameters of the probe are taken as 1.3mm and 4.1mm respectively. it is loacated at a radial distance of 9.9mm fromthe center of patch towards its cicrcumference. A shorting patch is located at center with radius 0.5mm is conne
I have been designing a Radar planar antenna at low frequency. The height of the substrate is h=15mm. So the practical antenna is showing an added +34j (50 ohms matched value) inductance then the simulated results. To model this antenna correctly in software (ie3d) i need to add this inductance to port ..... How can i do that in software?? Please
I want to design a microstrip antenna with probe feed from one side and not from below. the probe feed for patch option is not allowing to change the axis of the probe. I can create the probe as a cylinder but can not put a port at one end of the cylinder. It would really be of great help if someone has some suggestion.Thanks.
Hello all I am having a problem regarding ports in ie3d.I have simulated a geometry separately with advanced extension port and probe feed (with rad 0.63 mm). Feed position is same in both cases.But I am having completely different results.I cannot reason if anyone can please help.
I suggest u donnot try to model a complete coax in ie3d. It would be not only tedious but also unreliable. You can just use the strip model of the probe feed to simulate the antenna impedance. If the antenna impedance is adjusted to the desired 50 ohm, the combination of the antenna and the coax feed in the real world should work OK.
Hey Could you help me please , I want to see the effect of feed location on freq, Return loss & Bandwidth by varying the feed location along the length of the patch from the origin (center of patch) to its right most edge. The coaxial probe feed used is designed to have a radius of 0.5mm. the length and the width of the patch L = 22 mm,
hello, i want to know how can make L shaped coaxial probe feed using ie3d.PLEASE SOMEBODY HELP ME BY STEP BY STEP PROCEDURE. THANX REGARDS SAMEER
I am a new learner of ie3d. When simulating a L-probe feed patch antenna from a journal paper, its results are different from those shown in that paper. Would you mind helping me to solve it? The paper about the antenna is also attached in the rar file. Thanks.
Hi, I try to simulate an antenna from the book "Compact and Broadband Microstrip Antennas" in ie3d program. The books state that the design was also simulated in ie3d, however, my graph of the return loss is significantly different. My initial thought was that my probe feed was too big, however, making it smaller hasn't help. I've attached (...)
Hi to All, I'm newbie in antenna design and ie3d too. Where i can find the tutorial for probe Feed Microstrip patch antenna
Hi all! I'm new with simulation and antenna design. I'm triying to simulate a probe-fed rectangular patch antenna on a finite ground plane. I designed this antenna by transmission line model using fiberglass as dielectric substrate with Er=4.4 and h=1.52mm. The size of this patch is L=29.47mm and W=38.03mm. The size of the ground plane is Lg=3
hi frens, I did simulate the same set of antennas using ie3d and HFSS but did end up with different results.Did feed wid the same probe come the result be different..the resonance frequencies are real different in both cases.. Have you come across the same?? P.S. I did check one of a paper they had given the result from both the si
There are a few probe-fed examples in .\ie3d\examples and .\ie3d\training folders.
Phamton_gr: Normally, you don't need to have extra finer meshing for the probe location as long as you apply AEC. The s-parameters should be quite reasonable. However, if you really want to make some portion of the structure to have finer meshing, you can use ADV EDIT->MESH AND MERGE->MESH SELECTED POLYGONS. Regards,
HELP needed in designing a probe-fed shorted patch antenna operated at dual bands of 1.8 and 2.45 GHz. attaching the .geo & geometry. plz tel me where i wnt wrong, also if possible plz attach correct .geo file. thank-you
Hi,I'm now using ie3d software to draw my antenna design.Currently,I only draw out the patch and assume there is infinite ground plane.I'm using coaxial probe feed technique.But how can I define my dimension for my dielectric substrate since I cannot see the substrate block appear in 3D view?Or can use ie3d to draw out my substrate? Or can I (...)
When i am inserting a probe feeding to an antenna in ie3d,while defining the port, it is asking for positve and negative level and also the radius. Can anyone tll me how to choose their values and define the port
Hi, Neil: Your antenna is a modified inverted-F antenna. The probe and the shorting pin form a very small loop (compared to wavelength). It is causing very strong current concentration in that region. The strong current concentration there is causing much metallic loss even the sigma = 4.9e7 s/m. You will see the return loss is reduced significa
