Abstract
A radiofrequency transmission/reception device includes a first and a second conductive wire element, a first far-field transmission/reception chip and a second near-field transmission/reception chip. The first and the second wire element combine with the characteristic impedance of the second transmission/reception chip in order to form a coupling device associated with the first transmission/reception chip at the operating frequency of the first chip. The first and the second wire element combine with the characteristic impedance of the first transmission/reception chip in order to form a coupling device associated with the second transmission/reception chip at the operating frequency of the second chip.
