FIELD: antenna equipment.
SUBSTANCE: compact antenna includes: first element (23) having a pair of conductors with power supply point (32); and second element (24) as a conductor, between which a dielectric body is laid. Part of first and second elements (23, 24) has shape (34, 40) of inductance. First resonant mode (A), where the direction of the current of first element (23) coincides with the direction of the current of second element (24), has first resonant frequency (Fa0). Second resonant mode (B), where the direction of the current of first element (23) is opposite to the direction of the current of second element (24), has second resonant frequency (Fb0). Further, the length (Lm + S) from each power supply point to the shape of inductance is determined so as to maintain first resonant frequency (Fa0) in the range of a frequency slightly higher than second resonant frequency (Fb0), to high antiresonant frequency (Fbru) of second resonant mode (B), or in the range from a frequency slightly lower than second resonant frequency (Fb0), to low antiresonant frequency (Fbrd) of resonance mode (B).
EFFECT: proposed device is a small antenna.
