AIRPLANE ANTENNA ARRAY Russian patent published in 2012 - IPC H01Q21/00 

FIELD: radio engineering.

SUBSTANCE: airplane antenna array comprises n radiators fixed on the front wall of the airplane wind tip closed with a detachable fairing, and active SHF devices, inlets-outlets of which are connected with appropriate radiators, and outlets-inlets - with inlets-outlets of a summation circuit. The radiators are installed in the movable part of the wing tip perpendicularly to the transverse axis of its front edge, active SHF devices and the summation circuit are arranged in the fixed root part of the wind in compartments between power transverse dielectric diaphragms and are connected to the circuit of the airplane cooling system. In the airplane antenna array the radiators may be arranged in the left and right movable parts of the wind tip, and active SHF devices and the summation circuit - in the fixed left and right root parts of the wing. Wing compartments, in which SHF devices and the summation circuit are installed, are closed with a detachable radio-absorbing material.

EFFECT: reduced impact of arranged SHF devices at strength properties of the airplane, reduced temperature loads at active SHF devices, improved screening of deflected wing tip compartments, higher reliability and improvement of antenna array radiation characteristics.
