FIELD: radio engineering and communications.
SUBSTANCE: invention can be used in transceiving radio equipment, mainly in medium-wave and short-wave radio communication systems. Small-size resonance framing coaxial antenna consists of tuning and matching circuit and coaxial radiator. Tuning and matching circuit includes adjusting inductance coils L1-LN+2, adjusting variable capacitors C1-CN+2, separating capacitor Cp and transformer Tr. Coaxial radiator consists of N+1 coaxial frames, connected to each other at ends of shells electrically so that common shell is formed. Coaxial emitter is connected to adjusting variable capacitors C1-CN+2 by common shell and inner conductors of each frame separately from one end and to adjusting inductance coils L1-LN+2 from other.
EFFECT: high radiation power while maintaining small dimensions of antenna.
