摘要：
The present invention relates to a linear resonator (100) of a high-frequency antenna suitable for emitting a radiofrequency energisation signal and for receiving a radiofrequency relaxation signal, said linear resonator (100) comprising a radiating element (103) suitable for emitting a radiofrequency energisation signal and for receiving a radiofrequency relaxation signal. Said resonator also comprises: a balun circuit consisting of a power-supply line (133) and two coupling lines (131, 132); a substrate (120), consisting of a dielectric material, supporting said radiating element (103) which contains said balun circuit (130); two contact points (136, 137) connecting said balun circuit (130) to said radiating element (103), said contact points being formed by one of the ends of said coupling lines (131, 132) extending out of said substrate (120), the distance separating the two contact points (136, 137) being selected such as to ensure the impedance matching of said resonator (100); and a chip floorplan (111) separating said coupling lines (131, 132) from said radiating element (103, 303).
