hello i m sameer and i want to know that how to set the ground plane for inset feed in ie3d. well. i know how to set the ground plane for coaxial feeding but i m confused about inset feed. for coaxial feeding, we put 0 value of real part of conductivity for 0 layer in basic parameters. but you know when i follow the same procedure for the inset
hello this time, i want to know about inset feed using ie3d. in ie3d when we have to set the finite ground plane then we have to put the value 0 to real part of conductivity in the 0 layer in the basic parameters but we want to give inset feed then do we still follow the same procedure to set the ground plane for inset feed.
Hello, If you want to simulate such a structure in ie3d, you have to make the zero layer conductivity zero (in the basic parameters section). The ground plane as used in the antenna is just a metallic surface for ie3d. So if you are able to draw metallic surfaces in ie3d, you can just draw this ground plane as a polygon (...)
Hi, I am designing a 915Mhz microstrip antenna, and I am trying to simulate results using ie3d. I tried to simulate the two attached designs from Texas Instrument. However I am not sure how to define the ground planes, should I set layer 0 conductivity to 0 and draw a ground shape? what about the ground polygon on the top layer, how can it conn
hello i want to know that can i set the aluminium plate as ground plane with thickness in ie3d. in a paper which i m considering this is mention "An Aluminum plate with dimensions of 1.397λ0 1.257λ0 and thickness of 1 mm is used as the ground plane" i know how to set the ground plane in ie3d but i dont know how to set this aluminium g
i dont think dats d far as i ie3d finite ground plane is only possible by setting real part of conductivity of 0 layer to 0 and den d process i mentioned before.... regards
Hello, I don't know the version of ie3d you have, but the older ones do support limited ground plane, but infinite dielectrics only. This will give zero radiation under zero elevation, while the actual antenna may produce radiation under zero elevation. You can remove the infinite groundplane by changing the conductivity of the layer 0 under
Hello, I am trying to simulate a coaxial-probe-fed microstrip patch antenna to achieve some proven data. I am using ie3d EM Design System , Version 14.04. I used finite groundplane by defining No0. layer's conductivity to be 0, then drawing a rectangle as the metal ground. I used the method from section 16.2 of the ie3d manual to (...)
Hi, llololl: It seems to me you have built the shapes correctly. However, you have included a GND on ie3d. The GND will suppress the wide band charactersistics of the antenna. Please change the No.0 substrate's conductivity to 0 and you should get good results. Good luck! Regards, Added after 40 minutes:[/size
Chest: This is ok. It is just some message to you. ie3d users the polygons and vertices to do the meshing. If you have 2 vertices close to each other, ie3d may create a cell with tiny area but not tiny length. To the extreme, such a cell may cause numerical instability. ie3d gives you a warning on small edges formed by 2 vertices. If the (...)
