VERTICALLY POLARIZED TRANSCEIVER ANTENNA Russian patent published in 2008 - IPC H01Q1/38 H01Q13/20 

FIELD: radio engineering including antenna engineering, radars, communications, miscellaneous antenna assemblies disposed on flying vehicles.

SUBSTANCE: proposed vertically polarized transceiver antenna has radiator mounted perpendicular to screen plane. Radiator is made in the form of rectangular plate, 1.0 to 0.2λ_l wide and 1.0 to 0.15λ_l in height, where λ_l is wavelength of frequency range low value, which is shorted out and fixed through its bottom edge on screen. Antenna is excited through half-open slit, minimum 0.2λ_l long, made in rectangular plate at distance of 0.01 to 0.5λ_l from screen. Excitation point is free to displace along half-open slit and is chosen to ensure optimal matching in frequency band. Rectangular plate may have rounded-off tops with rounding radius of minimum 0.015λ_l. Half-open slit provided in proposed vertically polarized transceiver antenna may be rectilinear, or curvilinear, or variable-width piecewise-linear. Proposed antenna can be disposed in dielectric volume with fixed or variable dielectric constant.

EFFECT: enhanced gain and mechanical strength of proposed antenna.
