HIGH-STABILITY BROADBAND MICROSTRIP STRUCTURE Russian patent published in 2024 - IPC H05K3/00 

FIELD: microwave equipment.

SUBSTANCE: invention relates to ultrahigh frequencies and is intended for use in microwave devices for radar, radio communication and satellite television systems. In a structure comprising a ceramic substrate with a microstrip topology, a bearing printed-circuit board made from a material of the fibreglass type, a metal screen made in the form of a channel, contact jumpers, ceramic substrate is integrated with the printed circuit board so that the ceramic substrate is mounted on the metallization of the coplanar topology of the printed circuit board, screen is made from material of "kovar" type with highly conductive coating and is installed with shelves on metallization of coplanar topology of printed circuit board above ceramic substrate. Length of the screen is specially selected so that its edges are located above the coplanar topology.

EFFECT: wider operating frequency range with improved manufacturability of integrating a ceramic substrate and a printed circuit board, maintaining stability of the device under the effect of external factors in the form of changes in ambient temperature or mechanical load.
