    co-polarization and cross-polalization pattern

    copolarization Hi helio1972, I find this topic interesting. I'm not very knowlegeable of antennas. So, for a given antenna, is it desired to have Phi=0 pattern equal to Phi=90 ?

    Stacked dielectric materials setup in HFSS

    Hello, What is the proper way of simulating two parallel plates filled with 2 different dielectric materials stacked one over the other in HFSS? the results I'm observing my my simulations seem to suggest that the simulator assumes the boundary between the 2 dielectrics to be a perf-E and...

    How to determine the memory needed for HFSS simulation?

    site:www.edaboard.com hfss memory error Hi, Please can someone tell me how to determine the required Memory size needed when setting up a simulation in HFSS. For some reasons, the program keeps stopping in the middle of simulations and returning "...insufficient memory" error message. Thks.

    help (microstrip antenna with slot)

    Yea, i'm also working on patch antenna with slots to get multiband behavior. But i don't know where to start. Please if anyone could post an HFSS example of patch antenna, it would help. Thks.

    why my LNA gain is negative(db)?

    Hi ssdd, A negative gain for LNA suggest many things. First, your device may be blowned. This will cause your transistor to act more like a resistor at the gate-source region. I'm not sure which device you are using but, check the manufacturer datasheet to make sure that you're applying the...

    can anyone help me on design of patch with micromachining

    Re: can anyone help me on design of patch with micromachinin Yeah, I agree with the previous post. It's important to know what type of etching approach you're using. Is the inability of matching the impedance possibly due to over-etching of the substrate (or maybe the feed uline itself)?

    Useful materials about microwave absorbers

    Re: microwave absorbers Hi armsgroup, Microwave absorbers are also vital in the Remote Sensing (RS) arena. One particular book you might find useful if interested on the applications of microwave absorbers for RS is: "Microwave Remote Sensing: Active and passive" by F. T. Ulaby. regards,

    HFSS Edge-Coupled Bandpass filter. Help plz!

    bernard schmanski Hi an.t, It's difficult from your slide to see what exactely you're trying to accomplish. In term of 'meshing', it depends on the complexity of the design. Typically, you'll have more mesh at points of high current density (i.e. Via, bends ...) while other areas of the...

    what difference between lumped port and waved port?

    Hi, The strigent requirement for proper integration line as well as the assignment of the proper port impedance one has to perform in HFSS in order to use a lumped port suggests to me that, ALWAYS use a waveport whenever possible !
