hello,
it is said that to pass a high value of current a conductor with high thickness is needed. larger the value of current larger the thickness of conductor. it is true??? if yes plz explain why.
thank you
hello,
plz tell me about detuning of antenna and how it can occur. ??
i think when antenna came into contact with the radiation from another metal it detunes in some cases or
in devices where different components are integrated with antenna, currents induce on them or on the ground plane...
actually i m designing a balanced antenna for WLAN [2.4 GHz and 5.2 GHz]... shape of antenna is just like dipole. it is fed from center. i just need a balun to feed this antenna with coax....
i think its simple narrow band antenna radiating for above WLAN bands...
hello!
i am designing a balanced antenna just like dipole which is fed from the center. i need to design a balun to feed the antenna with aport of 50 ohm impedance.
can anyone tell me some thing about this..
i have no ideaa.
thanx
hello!
i need to design a coaxial balun to produce a balanced output from an unbalanced 50ohm transmission line...
can anyone help in balun deigning????
its urgent
i have no idea
thanxx
hello friends
can anyone tell me about E plane and H plane of a patch antenna designed on hfss.
how can we say that this is the E plane among [xy yz xz] planes.??/
plz tell me about this
thanx
your 3d plot is strange. i think value of theta and phi for far filed are
theta:-180-180 step size=2
phi:0-360 step size=2
this will show better plot.
you can also plot gain vs frequency same as s parameter plot in hfss in far field report.
hi all!
can anyone tell me about TE and TM modes in antenna. i am designing a patch[folded dipole type] antenna in hfss 11.
how these modes are related to antenna radiation or resonant frequency .i dont know anything about it. plz help
thanx
hi all!
guys is there any one who knows about measuring impedance of an antenna designed on hfss. this is probably through smith chart. i dont know how the impedance can be interpeted using this as smith chart shows many circles and some thing strange like a circle which is having many turns...
hi
i am a new user to this fields calculator. i have to calculate patch antenna's current distribution on the surface(Jsurf) which will be different everywhere. can anyone help in calculating and plotting this in MATLAB. i have to submit my project soon.
thank you
