Abstract:
1. A receiver with an antenna circuit, configured to capture a near field signal with a wavelength transmitted by a transmitter wherein the near field signal includes a reactive magnetic field and a reactive electric field said antenna circuit comprising: a coil that captures said reactive magnetic field and generates therefrom a current having a frequency corresponding to said wavelength, wherein the largest dimension of said coil is less than 5% of said wavelength and said coil being dimensioned such that said current is distributed uniformly across said coil at each point in time; and either a monopole antenna or a dipole antenna connected to said coil and that captures said reactive electric field, wherein the length of either said monopole or a leg of said dipole, as applicable, corresponds to less than 5% of said wavelength; wherein the receiver is configured to receive a frequency of up to 30 MHz.
