BROADBAND MICROSTRIP ANTENNA WITH TRAPEZOIDAL CROSS SECTION Russian patent published in 2013 - IPC H01Q1/38 

FIELD: radio engineering, communications.

SUBSTANCE: radiating element of a microstrip antenna comprising a rectangular radiator, arranged above a screening surface with an H-shaped slot and excited by a microstrip line with a train, is bent in direction of radiation of the microstrip antenna, so that in the cross section it has a trapezoidal shape, symmetrically relative to the plane of symmetry of the microstrip antenna, stretching via axes of symmetry of a rectangular metal screen with an H-shaped slot, the rectangular radiating element and the exciting microstrip line.

EFFECT: increased coefficient of antenna amplification and band of working frequencies by level of reflected power.
