BROADBAND HORN-MICROSTRIP ANTENNA Russian patent published in 2010 - IPC H01Q13/02 

FIELD: physics; radio.

SUBSTANCE: invention relates to radio engineering, particularly to broadband microwave antennae. The antenna has a horn and a resonator. The horn is made from metal and has the shape of a right cylinder with a rectangular section, the rear wall of which is a screen-reflector. The resonator metal plate is placed in parallel to the screen-reflector and has a coplanar waveguide and a flat-topped load axes of symmetry of which coincide and are perpendicular to two oppositely lying lateral faces of the horn with large dimensions and pass through their axis of symmetry. The top part of the flat-topped load of the coplanar waveguide of the resonator plate has symmetrically projecting strip elements whose location and dimensions are determined by the value of the given operating frequency band. The coplanar waveguide is made from a straight current-carrying conductor whose location coincides with the axis of symmetry of the coplanar waveguide. On one side, the current-carrying conductor is electrically connected to the edge of the flat-topped load at a point lying near the centre of the resonator plate. Two external conductors of the coplanar waveguide adjacent to both sides of the current-carrying conductor have a symmetrical stepped shape which is determined by the value of the given operation frequency range.

EFFECT: efficient reception and transmission of broadband microwave signals with minimisation of the size of the antenna.
