BROADBAND ANTENNA Russian patent published in 2022 - IPC H01Q1/36 

FIELD: technology.

SUBSTANCE: invention relates to antenna technology, in particular to broadband antennas. The effect is achieved by the fact that a broadband antenna containing a vertical conductor installed with the help of the first insulator on the upper end of the tubular base made of a conductive material, a high-frequency matching unit and an input coaxial cable built into the tubular base, and also installed on a horizontal screen and having it is a galvanic contact - a conductive body, on which, with the help of a second insulator, a tubular base is installed with its lower end, and in the housing there is a block of switches and a segment of the transmission line, it differs in that the vertical conductor is made of a pin, and the reactive LC-two-terminal network on adjustable elements and a low-frequency four-pole matching device are introduced into the antenna, placed in a conductive housing and connected by their terminals to the block of switches, at the same time, the ratios of the overall dimensions of the external parts of the antenna are determined.

EFFECT: increasing the efficiency of the action and the radiated power of the antenna in the low-frequency region, as well as expanding the operating frequency range of the antenna towards lower frequencies.
