    Coaxial feeding problem

    Hi, I have designed a square patch antenna (15,5mm x 15,5mm) and I want to feed it with a coaxial cable. My first thought was to use an SMA connector with the following dimensions: ext. diam. 4,1 mm / int. diam. 1,3mm In my opinion, compared to the patche's dimensions this connector is too big...

    Measurement of Transm. coef. in FSS using HFSSv.10

    Dear cd79, Thanks for the quick reply. My experience is limited as I am currently studying at the university. The problem goes like this: I use master/slave boundaries to create periodicity but only in one direction. I mean that the periodicity creates an infinite structure of rods as far as...

    Measurement of Transm. coef. in FSS using HFSSv.10

    Dear collegues, I am currently simulating an FSS structure using Ansoft's HFSS v.10. The structure consists of two series of dielectric rods placed one above the other separated by vacum and forming a kind of a parallel plate waveguide. I use a plane wave to excite the structure. The excitation...
