A method for manufacturing a magnetic dipole antenna employing one or more spacers is disclosed. The magnetic dipole antenna having three plates, where each plate has holes for inserting one or more spacers through the bottom and middle plates. The distance separation between the top plate and the middle plate of the magnetic dipole antenna determines the operational frequency. Spacers are used to adjust and secure gap between top and middle plates and fix operational frequency of antenna at desired target frequency. A coaxial cable is attached to the magnetic dipole antenna for measuring the resonant frequency.
