MICROWAVE SIGNAL POWER DIVIDER AND ANTENNA ARRAY Russian patent published in 2024 - IPC H01L23/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering, in particular to a microwave signal power divider with a built-in resonant contactless terminal load, which can be used, for example, in multi-element antenna arrays, containing such power dividers. Microwave signal power divider, implemented on a printed circuit board, includes an input arm, two output arms and a terminal load integrated into the printed circuit board, wherein each arm of power divider includes transmission line with impedance Z0, each output arm of the power divider further includes the main branch of the power divider and an additional branch of the power divider, main branch of the power divider connects the transmission line of the input arm and the transmission line of the output arm and has a length which is a multiple of , additional branch of power divider extends from the point of connection of the main branch of the power divider with the transmission line of the output arm to the plane of symmetry of the terminal load and has a length which is a multiple of , additional branches of power divider are interconnected in plane of symmetry of terminal load, terminal load is located above the exciting transmission line and includes an intermediate slotted radiator and a power absorption component located on the outer layer of the printed circuit board, exciting transmission line and intermediate slot radiator are connected to each other by means of electromagnetic coupling.

EFFECT: reduced losses, increased reliability of power divider operation, provision of high isolation between channels, and also increased efficiency of operation of antenna array containing such power dividers.
