UNDERGROUND PATCH ANTENNA OF METER WAVES Russian patent published in 2024 - IPC H01Q9/00 

FIELD: antenna equipment.

SUBSTANCE: invention can be used as a meter-wave range receiving device antenna. Underground patch antenna of meter waves comprises an underlying surface in the form of a square metal substrate, on which there is a dielectric material in the form of a rectangular parallelepiped with a square base, which forms a first insulating layer, wherein four square metal sheets are placed on it, equally oriented at the corners of the first insulating layer, which are upper plates of open resonators, centers of which are connected by metal vertical bridges with metal substrate through holes in first insulating layer, on said metal sheets there is a second insulating layer of dielectric material in the form of a rectangular parallelepiped with a square base, oriented along the vertical axis of symmetry of the antenna, wherein a square metal sheet (patch) is installed on it, wherein two metal rods (excitation elements) are connected to its lower surface at points equidistant from its center, arranged orthogonal on two axes of symmetry of horizontal plane in holes of two insulation layers, wherein the dimensions of the second insulating layer and said square metal sheet (patch) are smaller than those of the first insulating layer and the first metal sheet, note here that said elements are arranged in pyramid-like antenna.

EFFECT: patch antenna with two metal rods provides full-azimuth reception of electromagnetic radiation.
