MICROSTRIP ANTENNA Russian patent published in 2018 - IPC H01Q1/00 

FIELD: antenna equipment.

SUBSTANCE: invention relates to an antenna technique and can be used as a receiving or transmitting antenna or phased array antenna element in radio communication or radiolocation systems. Antenna comprises a first dielectric layer having a first printed emitter on the upper side and a first screen from the lower side, a second dielectric layer disposed above the first dielectric layer, a second printed emitter positioned above the first printing emitter, a third dielectric layer disposed above the second dielectric layer, a fourth dielectric layer disposed below the first dielectric layer and a fifth dielectric layer disposed under the fourth dielectric layer, the power divider is located on the upper surface of the fifth dielectric layer, from which the first printed emitter is fed from below. First and second printed emitters have a square shape, the first printed emitter is fed from the power divider through a matching printing element adjacent to the lateral surface of the first printed emitter, the dielectric material of the second dielectric layer has a permittivity of the order of 1, the ratio of the thickness values of the second and first dielectric layers is not less than 4, the second printed emitter having overall dimensions exceeding the dimensions of the first printed emitter, and the arrangement of the pairs of the first and second printed radiators is made at an equidistant distance at the nodes of a rectangular or triangular grid.

EFFECT: technical result is an increase in the band of operating frequencies of the antenna by decreasing the dielectric constant and increasing the thickness of the second dielectric layer.
