Microstrip patch antenna not converging

Hi everyone, Building a microstrip patch antenna on HFSS. I used a wave port and de-embedded it to start on the beginning of the inset feed of the transmission line. During the solution, the convergence is not happening even though i have 30 passes with DS = 0.01. The results are very big like 5.7e+86 etc.. Any thoughts? (...)

Inset Feed Calculation Patch Antenna

I would like to calculate the inset feed dimensions for my patch antenna, Peak Impedance (impedance at edge) is 155.9072 +50.9807j. I rearrange the formula: 121564 with 50 ohms being the one you want, Zin(R). My question is, in the calculation, for the other impedance value Zin(0), should I use 155.9072, or the m

Relation of inset feed point and resonant frequency of an inset fed patch antenna

Hi all! I was simulating a simple inset fed patch antenna on Taconic TLC with Dk=3.2 and thickness of 0.79 mm at 2.45 GHz. While finding the inset feed position for optimum impedance match, what I observed was that the resonant frequency changes when I change the inset (...)

Microstrip patch antenna inset feed width -HFSS

Hi, We designed a microstrip patch antenna using HFSS having the following parameters shown in fig. 89522 In this fig, when the inset distance is varied slightly ie even by 0.001mm also, the impedance decreases drastically. This could be pretty dangerous when manufacturing the antenna is in question. Is there any soluti

Inset feed not working on simulation

Even if there is a gap, there should be some coupling. Sure, but the capacitance across the gap is small. Any gap between the feedline and patch will cause heavy mismatch. patch and feed dimension checked? Substrate permittivity checked?

Inset characteristic of a microstrip patch antenna at 12.1 GHz on glass substrate

Let's assume that the inset gap length used by the questioner means the width of the inset gap, which is the dimension along the same direction as the patch width. One antenna textbook says that the inset gap length commonly is 3 times of the feed-line width. However, if the (...)

Help with design of inset feed patch antenna

So, is there actually no equation in order to design the dimension of the microstrip line?? The width of the microstrip line (Wf in your picture) is given by the line impedance (usually 50 Ohm). The slot width (equal to Wf in your picture) should not be critical. ---------- Post adde

help please,it's urgent: double inset feed patch antenna

Hi, The dimensions you gave now are quite different from the first patch. I don't understand with respect to which condition "the frequencies shifts about 0.3-0.5 GHz to the origin". Can you clarify? In your case, the gaps necessary for the port 1 (or 2) inset cut the patch where the current is maximum when you feed by (...)

Inset Feed Length,Width

The inset is to match the antenna to the feed, different points of the patch have different impedances, depending on the mode. I suggest you to consult microstrip antenna design handbook by Garg: or any other microstrip antenna handbooks.

Best antenna design for a elastomeric substrate

Hi, I am working on developing a stretchable antenna. Currently i tried simluating a 2.5 GHz inset fed patch antenna on the elastomeric substrate but i see that the reflections increase when it is stretched more than 10%. This maybe because we disturb the inset position while stretching. I thought like a (...)

rectangular patch antenna design

Well you can choose a microstrip inset feed patch. The length of the patch is given by L = c/(2*freq*sqrt(dielectric-constant)) and take width 1.2 times the Length (This is not a rule, I am saying so that you can begin your analysis) Then feed the patch in the center

How to know whens the highest reflection on E-Field Monitor

Hi abti, What type of planar antenna are you looking at ? If it is a microstrip patch antenna with microstrip feed on the same substrate, then you should look at varying the inset position and adjusting for lowest possible S11. Similar thing holds for a probe fed patch (...)

microstrip antenna: inset feed vs L/4 trans.

Please take a closer look at Balanis book. There is indeed a formula for you to calculate the depth of inset. Now I am using Ansoft Designer on the same 2.45G inset-feed square patch antenna. The formula is quite good in Designer for the 50-ohm matching. But the problem is its narrow-band (...)
