QUASI-SHUNT DIRECTIONAL ANTENNA WITH RESONATOR POWER Russian patent published in 2021 - IPC H01Q19/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering, namely to antennas with vertical polarization and a sectoral radiation pattern in the horizontal plane, and can be used as directional antennas for wireless networks, mainly in the ISM range. The technical result of the invention is achieved by the fact that the proposed quasi-shunt directional antenna with resonator power, made in the form of two rigidly connected metal rods and containing a half-wave vibrator, powered from its lower end through a matching device in the form of a quarter-wave open line, closed at the lower end, with vertically located parallel to the axis of the half-wave vibrator with an active reflector and at least one active director, with shunt power devices connected by connecting conductors to the half-wave vibrator, characterized in that the connecting conductors of the reflector and director power are made in the form of single-wire lines and are connected to the lower end of the half-wave vibrator and in the upper power-on points of the reflector and director shunts.

EFFECT: possibility of expanding the bandwidth of the operating frequencies and of adjusting the radiation pattern width while simplifying the antenna design.
