FIELD: radio engineering.
SUBSTANCE: invention relates to antenna engineering, namely, to single-layer microstrip antennas intended to be used in SDMB frequency range. Concept of the invention is that single-layer microstrip antenna comprises 1) base, 2) emitter in the form of ring or polygon, and 3) feed strip, separated from emitter by a constant value interval; emitter and feed strip are located at the antenna base. Thickness of single-layer microstrip antenna base can be from 1 mm to 1.9 mm. Single-layer microstrip antenna can have a chip resistor for impedance match.
EFFECT: providing optimal circular polarisation at minimal size.
