    Retrieving the refractive index

    hi all To correct the ambiguity in m based on IEEE MTT and AP papers you have to choose m=-1, 0 or 1 then for a single frequency, calculate the S11 of the extracted material and compare it with CST simulation! regards

    uwb antenna discussion

    you should use a vacume that it is larger than from the maximum size of your antenna about lambda/4 and it is better to use an infinit ground plane

    uwb antenna discussion

    dear romeo 1- are you considered the finit or infinit ground plane? it is too important. 2- are you considered the lambda/4 condition for simulation?

    Sinuous Antenna, Design and Simulation

    oh ok! so are you simulated the feeding network. i saw your thesis, in your thesis you only presented the Duhamel approach for hybrid and couplers. are you could find any other approach for it?

    Sinuous Antenna, Design and Simulation

    hi yuanboshybshyb yeah in lower frequencies the antenna gain is about -2 to -3 dBi while for higher frequencies it is increased to 5 dBi. Added after 5 minutes: dear Aya2002 i desigend and implemented this antenna two years ago. are you implemented it? if yes, what did you do for feeding...
