## check my attached file and guide me

hello I have attached the paper. i have worked on it this but as i am new to antenna and hfss i have so many doubts. My S(1,1) paramter almost matched with the paper but i am not able to plot the radiation patter and not able to compare the results with paper. i have tried to plot x-y, y-z, x-z pattern but i dont know that did i plot them correct

## wave guide simulation

I am simulating a waveguide in hfss having 2 ports( rectangular dielectric waveguide) .I want to ask what is real meaning of S(1,2) because in one case i am getting S(1,2) plot showing 5db gain while the propagation constant (beta) is equal to 0. Field overlay also shows wave dying much before even reaching port 2 then how to interprete (...)

## Hfss rectangular waveguide Problem

What size waveguide are you using? To my knowledge, nobody ever uses waveguide at frequencies in the range 100 Hz to 10 kHz. It would need to be absolutely huge. I forget the width/height/frequency relationships, but the width and height are of the order of λ/2. So for 1 kHz, you are looking at a waveguide with a hieght of around 75 km. (...)

## problem solving HFSS Rectangular wave guide.

Dear Aparna,i think Error is due to the fact that you might be using a lower version of hfss,what version of hfss are you using.if i check your file and save it in on me computer you wont be able to use it anymore because hfss files are not backward compatible unfortunately Best Regards Sajid Mohammed.

## Problem doing UHF probe example in HFSS

## solve ports only on Hfss 12

Hi Carole, I personally use the solve ports only in hfss to find the right size of my waveports and prevent higher modes propagation. Often at microwaves you have to deal with these higher modes. I advise you to take a look at the hfss user's guide for this port analysis. Hope it helped a bit, JB

## HFSS problem: single probe feed patch antenna.

Hello, recently I tried to simulate the probe feed patch antenna in the Example 5.3 of hfss user guide V10. Page 200. In the example project, the position of the coax and the probe pin are at x:-0.5 y:0.0 z:0.0. I followed the steps of the example and got a good simulation results. However, if I tried to turn the coax and feed pin 90 degree to y

## substrate integraded wave guide what is the purpose of via

Hi Metalized via holes are playing the role of lateral side walls of a ractangular waveguide. You must have an error in your simulation. Usual mistake when using hfss is failure to set substrate interfaces to radiation boundaries so that top and bottom walls are not connected by vias only but are in addition automatically connected together t
