printed dipole design

how to design a printed dipole antenna for a resonant frequency of 866 mhz.
 

Re: printed dipole design

thanks for the paper. I would like to design the printed dipole without a ground plane.so will the same formulas for length, gain from the paper hold good in my case?
 

Re: printed dipole design

Offcourse for printed dipole there will be no ground plane other wise it will be patch antenna.

Yes same formulas are valid.

Please let me know when you will complete the antenna simultion.
I would also like to see the results.

BR,

Re: printed dipole design

using the formulas provided in the paper, after simulation it is resonating somewhere around 16oo mhz instead of 866. my dielectric constant is 4.5, thickness of dielectric is 0.8mm and width of radial is 3.5 mm. what according to you should be the length of the dipole in this case?
 

Re: printed dipole design

looks like it is resonating at 2nd harmonic.
check your feedline.
You need to do some length tuning.
