    Simulation of split ring resonator (SRR) with HFSS

    I get the exact results as the Smith 2005 paper. Copie de SRR1.rar is the right file. u can use it. plot the S11_mag, S21_mag, -1*S11_phase(in rad), -1*S21_phase(in rad) right click on the plotted figure, and export the plot to a text file. use Excel to delete the first lines which are included...

    Help : RF to DC converters

    u can use HSCH-5531 Schottcky diod as it's been used by the previously attached paper titled "Adaptive power ..." (page:3). u can find its datasheet in www.datasheetarchive.com here is the JNL caihalo wantd me to upload:

    Help : RF to DC converters

    you can use the diodes in series to increase the output voltage. take a look at page 5 of the attached paper from Itoh, they got 1V output!

    430-470MHz, 6dBi Patch Antenna?

    My reference book is "compact and broadband microstrip antennas" by Wong. Yes I have ADS, but it is not good for probe-feds but acts very good for line-fed antennas. The above book uses entirely IE3D and because I tried several antennas from there in HFSS and CST, I guess these softwares are not...

    430-470MHz, 6dBi Patch Antenna?

    I also got the same result as you got. but as you compare to the pdf I sent previously these results are quite different from the measurement. so I really cannot design my own patch antenna because I cannot trust the results of the CST and HFSS in this case. yes you are right I can use...

    430-470MHz, 6dBi Patch Antenna?

    even this very simple coax fed transmission line does not work (CST file)!!!
