FIELD: radio engineering.
SUBSTANCE: invention relates to wideband small-sized surface-mounting antenna. Proposed antenna incorporates inductors (L1) and (L2) coupled magnetically, resonance LC-type circuit consisting of inductor (L1) and capacitors (C1a) and (C1b), as well as resonance LC-type circuit consisting of inductor (L2) and capacitors (C2a) and (C2b). To emit electromagnetic waves, multiple resonance LC-type circuits are used to make matching circuit to match impedance (50Ω) of the device to be coupled with supply terminals (5) and (6) and with impedance of free space irradiation (377Ω).
EFFECT: wider frequency range.
