FIELD: radio engineering.
SUBSTANCE: device includes insulating substrate having the first surface, radiating stub on the first surface of insulating substrate and the first grounding plate on the first surface of insulating substrate to be ground connected. The first grounding plate includes one or more grounded capacitive stubs equally spaced from radiating stub. One or more grounded capacitive stubs tune operating characteristics of antenna chain.
EFFECT: cost reduction.
