I'm simulating a slot-fed dielectric resonator antenna (DRA) with a parasitic strip. The simulated structure is as follows: 1- Microstrip line etched on the bottom side of the substrate 2 - Slotted ground plane (PEC) on top side of the substrate 3 - DRA placed on the ground plane 4 - Parasitic conductor element etched on the top side of th

hi , I have a problem that when I make a dipole antenna parallel to the PMC the radiation pattern is wrong so can someone help me with the steps or something like that ?!
Magnetic: Operates like a perfect magnetic conductor, where the tangential components of magnetic fluxes and the normal components of electric fields are zero. This means that electric fields are parallel to the boundary and magnetic fluxes are normal to the boundary. For all magnetostatic or magnetoquasistatic applications magnetic boundary condit
Hi EveryOne, I am looking to cater this error on CADFEKO Error "3849 Wrong medium specification" which I am getting while desining a microstrip patch antennas. Can some one kindly assist on this Structure of antennas involves following layers Ground Plane Finite which is perfect ELectric conductor Air which is formed by Cuboid defining
If you consider your copper electrodes as perfect conductors (if you don't care about field penetration into the conductor or resisitive losses) you can simply assign perfect-E boundary condition to these faces.
Hi all , I am making some test on hfss , I create a dipole antenna on HFSS , and I want to see how react with a perfect magnetic conductor , I have try to use a perfect H boundary in a surface under the dipole , but nothing change ! i do not understand this some one know why is this happening ?
Physically, there is no global ground. Ground is what you call ground, where you place your port's reference pin. However, even if you use PEC (perfect electric conductor) two points at some distance will have (and must have) delay and inductance between them.
Is it possible to define internal CPW port in HFSS simulation? - - - Updated - - - In one of the HFSS training manuals, it is given that : " Wave Port Restrictions: Port should be on exterior model face, or capped by a perfect conductor block if internal." Here, what does capped by a perfect conductor mea
How can I make the face of a cube perfect magnetic conducting in CADFEKO
I tried to make a S11 based measurement of a chip capacitor in HFSS (simulated measurements) I made a 50 Ohm microstrip line of layered impedance rectangles, put a rectangular patch at the end and applied 0.55 pF capacitive boundary to it. Other side of the capacitor is shunt with another vertical rectangle with perfect conductor layered impedan
Because EM radiation is nothing without the E. perfect conductor allows no E-field.
this looks like rogers substrate. not FR4. Are you sure about that? Copper as perfect conductor. infinitely thin planes are good enough. Are you using HFSS? Radiation boundary is set a box around the object. (size depending on the solve frequency).
Use Momentum will cover your whole structure by a closed perfect conductor. For more information, read relevant help topics.
I have a parallel plate capacitor. There is a plastic box in between the plates, touching the plates. I uesd lupmed port to excite this capacitor and used one face of this box to assign the port. The boundary condition for lumped port is to have to perfect E for the conductor on both sides of the port and perfect H for all other edges.Should (...)
Hi Mads, Could you please say more detailed about this lumped port? Where did you place the port and the perfect E sheet? It will be even great if you could upload your project file. Thank you very much!
cst microwave...oh ok..does PEC is same with copper?i mean in terms of its characteristics No, different. PEC = perfect conductor (lossless) Copper has conductivity 5.8e7 S/m. The thickness of your RT5880 copper can have different values, so you need to check what copper thickness you have. There are two different sur
If you need to take loss into account, then you are going to need to use finite conductivity. But if you can ignore losses, then a waveguide needs to consist of nothing more than the dielectric, as the background material is PEC - perfect electrical conductor. So all you need is a box (for rectangular waveguide) or a cylinder (for round wavegui
All the waves get reflected when it is strike a perfect conductor.Why?
In HFSS, you need not to make them (patch and RIS) to assign them as perfect Electric conductor, rather what you should do is to select your patch and RIS and assign them as pec material, you may do so by drawing patch as a 3D figure (accounting for a very small height/thickness of the patch over the substrate) for example: you may draw a cylinder
