A receiver ( 30 ) with an antenna circuit is disclosed, which antenna circuit comprises a coil ( 31 ) and either a monopole ( 35 ) or a dipole connected to the coil ( 31 ). The antenna circuit captures a signal with a wavelength transmitted by a transmitter ( 1 ). The coil ( 31 ) captures the signal and generates therefrom a current having a frequency corresponding to the wavelength. The coil ( 31 ) is dimensioned such that the current is distributed uniformly within the coil ( 31 ) at each point in time. Preferably, the monopole ( 35 ) or a leg of the dipole has a length corresponding to less than 5% of the wavelength. The invention further relates to a radio transmitter of the same kind. Finally, the invention relates to an RFID tag, a smart card, a mobile device, and a hearing aid, each comprising an inventive receiver ( 30 ) and/or an inventive transmitter.
