hi, i have no idea of fabricating antenna. if i have substrat, SMA then how can i fabricate a planar antenna ? that is how can i made copper pattern printing on substrate? i have no factories around me that can fabricate antenna so i want to fabricate it for myself.
secondly for measurements i...
satish, can you help me in understanding that if you will get the print then what will be next step of fabricating antenna?that is how will you fabricate it? i have no idea about it.please tell me, you will use electroplating for fabrication?
well i have asked them but got no answers from them, in a clear way what i understand is that i have values of Etheta ,Ephi with theta carrying from -180 to 180.now i want to re plot gain versus theta curve using these given values,my question is that is there any formula to calculate gain(db)...
hi,
i have asked this question before in this forum but get no reply,may be i was not precise in my question
i have got measured result of radiation pattern from anechoic chamber,this result contains columns of angle(theta) vaired from -180 to 180,and other column is Etheta (amplitude).now i...
Re: how to plot radiation pattern measured
daven,
actually i have not performed it myself ,ancheoic chmber in my lab is out of order so i take help from other school but according to their policy they dont allow me to do this but gave me this data and a figure of theta versus gain curve. i am...
how to plot radiation pattern measured
hi,i have got measured results of my antenna in ancheoic chamber and that results have an excel file which have 6 columns but i don't understand whats that column means.i have attached the figure here

thanks hva,
but i have got measured results of my antenna in ancheoic chamber and that results have an excel file which have 6 columns but i don't understand whats that column means.i have attached the figure here

how to study measured radiation pattern
hi, i have got a 2 Dimensional gain versus theta graph after measurements from anechoic chamber,as facility was not in my school so i dont know about it more but other school gave me figure of 2d graph and a data sheet that inchludes 6 column ,1 columns...
thanks a lot bob for your answer but i have sought out this by soldering, if you can guide me about circular polarization measurement?how can CP be tested?i have seen a paper in which they have made measurements of CP by getting axial ratio versus frequency but as its my first time with antenna...
hi,
i have got my antenna and balun after fabrication but my its my first time to deal with antenna fabrication now i have two things to ask
1. how can i connect my antenna with my balun?as my balun is exponential tapered M/S line that will be placed verticallly below antenna substrate.should i...
hi, rube,have you succeeded in converting it into pcb format?if yes then please send me. i have convert it and send it to factory but they are unable to open it. plz if you can help me?
hi ,if any antenna designer helped me in understanding one thing , i have simualted antenna on substrate of dimensions 26*26 mm while for impedance transfer i have take a balun of dimension 10*40mm now i am not sure either my structure will remained balanced when i will attach my balun with my...
