WIDEBAND SMALL-SIZE FERROELECTRIC-CERAMIC ANTENNA Russian patent published in 2016 - IPC H01Q19/09 

FIELD: antenna.

SUBSTANCE: invention relates to transceiver antennae for receiving and transmitting both digital and analogue signals. Antenna includes active element connected to grounding board made in form of parallelepiped of size L×W×H, where L is length, W is width, H is height, from ferroelectric ceramic material with high dielectric permittivity value ε≥1000 in working frequency range, and with anisotropic values of frequency dispersion of dielectric permittivity in body of active element: along its height: ε_H(ω) and at its base: ε_LW(ω) with ratio ε_H(ω)/ε_LW(ω) < 0.7, and also residual polarization σ≥2 mcCl/cm² at boundary of active ferroelectric ceramic element with air, and into body of active element exciter is built in form of current conducting rod, located perpendicular to base, wherein electrodynamic exciter length is equal to . To exciter, current lead in form of micro-strip is connected, lying continuously on top, lateral, and bottom surfaces of active element and having electrodynamic length to exciter equal to where l is total length of micro-strip on upper and lower surfaces of active element, wherein active element is arranged in plane of printed circuit board of transceiver (mobile telephone) in area, where current conducting elements of printed circuit board are absent, and at distance not less than (0.7-1) H between long side of active element and earthing conductor of printed circuit board.

EFFECT: technical result consists in producing working band of about 2 GHz in range 0,7 to 2,75 GHz, and broader functional capabilities.
