    a question about emission level for UWB antenna

    FCC regulates the ERIP level of UWB antennas. according to the calculation of ERIP of the antenna, i got several questions. if we define H(ω,θ,Φ) are the radiation transfer function in the specified angle(θ,Φ) (H(ω,θ,Φ)=E(ω,θ,Φ)/Vin). :?: Is it correct if we know the H(ω,θ,Φ) and the pulse...

    planar anenna on metal sheet or on the PCB

    I Want to know if a metal planer antenna is printed on a PCB SUBSTRACT without the ground plane, which difference of the performance will be produced, such as the efficiency, bandwidth, the input impedance? someone told me only the effeciency will be decreased, i am doubt about it, any one can...

    which software is the best to simulate the PRINTED DIPOLE

    printed dipole hfss i want to simulate a printed dipole on a PCB substract, and i want to know which software is the best one to realize this. in addition, i 'd like to tune the structural parameters (such as length, width and angles etc.) for optimization of the design, so the structure of the...
