LINEAR RECEIVING ANTENNA ARRAY OF ADS-B STATION WITH CIRCULAR AZIMUTH DIRECTION AND BUILT-IN GLONASS/GPS STANDARD ANTENNA CHANNEL Russian patent published in 2023 - IPC H01Q1/00 H01Q1/38 

FIELD: antenna technology.

SUBSTANCE: invention is related to linear receiving antenna arrays with a circular azimuthal radiation pattern, operating in the microwave range. The result is achieved by the fact that a linear receiving antenna array with a circular azimuthal radiation pattern is proposed, containing a vertical support in form of a hollow metal cylinder, an antenna channel of the GLONASS/GPS standard, a distribution system, radiators, while the distribution system and radiators are made based on a conformal symmetrical strip line in form of a multilayer structure, which differs from the prototype in that inside the vertical support of the linear antenna array, a bandpass filter is structurally built-in, connected by means of the first RF cable to the input of the N-channel power divider, and a low-noise amplifier, the input of which is connected to the bandpass filter, and the output is connected with a second RF cable, the free terminal of which is the output of the antenna array.

EFFECT: ensuring signal reception at the ADS-B station when installing a receiving antenna array on mast structures at a considerable distance from the receiving equipment.
