RECEIVING ACTIVE AERIAL Russian patent published in 2009 - IPC H01Q1/38 

FIELD: physics.

SUBSTANCE: active antenna contains slot coupled antenna component and the input of low-noise amplifier. It is ensured by slotted coupling holes of the same geometry and slot width to length ratio 0.1...0.2 respectively. These holes are formed within the plated layer of substrate interior and within earth board surface of low-noise amplifier. They are arranged specifically under the printed wire, while input circuit of the amplifier presents microstrip segment provided under the specified perpendicular coupling holes. It is supplied with diode assembly. The low-noise amplifier board is electroconductive fixed on the plated lower board surface thus ensuring the slotted hole within earth board plane of the low-noise amplifier under the slotted hole within the plated layer of substrate interior.

EFFECT: higher technological effectiveness and reliability of receiving active antenna.
