SMALL-SIZE WIDEBAND ANTENNA Russian patent published in 2017 - IPC H01Q9/00 

FIELD: radio engineering, communication.

SUBSTANCE: in the design of antenna multiband characteristics are achieved by grouping multiple band antenna special geometry dielectric material basis and embedding lumped reactive elements (inductors, capacitors and their integrated versions, such as slits), that forcibly cause new resonance frequencies.

EFFECT: expanding the frequency band of the antenna due to the creation of a special geometric design, which significantly reduces its size.
