Embodiment Construction

[0011] refer to figure 1 . figure 1 A preferred embodiment of the conformal integrated array antenna unit of the present invention is described. It includes, antenna conformal radiator and transceiver T / R assembly. The transceiver T / R component is an active transceiver T / R circuit module. The antenna radiator is a slotted metal thin-wall cavity with a conformal curved surface whose structural shape is adapted to the environment where the antenna is placed on the aircraft. The metal conformal curved surface thin-walled cavity constitutes the main body 1 of the antenna radiating unit adapted to the outer edge structure of the wing. The two sides where the front and rear non-radiating slits of the metal cavity of the main body 1 of the antenna radiation unit are used as the connection surfaces of adjacent antenna array units are parallel planes that facilitate the arrangement and combination of a plurality of such antenna units into an antenna array. The transmitting and rece...

Abstract

The invention relates to a conformal active phased array antenna unit. An antenna radiator (1) is provided with a conformal curved thin-wall cavity whose structural shape is matched with a placing environment of an outer slat cavity of an aircraft wing; a transmitting / receiving circuit board is fixedly connected with the inner part of the conformal curved thin-wall cavity of the antenna radiator;the outer radiating surface of the conformal curved thin-wall cavity is provided with a radiating slot (2); the slot cavity of the radiating slot is fixedly connected with a feed mechanism (3); the feed mechanism (3) is connected with a transmitting / receiving circuit (4) and is used for finishing the radiation and the reception of electromagnetic waves; and input and output signals facing to a receiving machine and a power supply interface of the transmitting / receiving circuit (4) are arranged on an interface seat (5) of a back wall plate of the antenna radiator. The structural body of the slot cavity matched with the structural shape of an antenna placing environment is used as an array antenna radiation unit as well as a packaging box of the transmitting / receiving circuit. The inventionsolves the problems of mutual separation, cascaded dispersion, large occupation space, heavy weight, non-compact structure and high manufacturing cost of the antenna radiation unit and a transmitting / receiving assembly in the prior art.

Description

technical field [0001] The invention relates to a conformal integrated array antenna unit, which is an active integrated array antenna unit which is conformally integrated with the antenna installation environment. Background technique [0002] At present, on some advanced combat aircraft, due to the consideration of the aerodynamic performance and low RCS performance of the aircraft, it is often required that the shape and structure of the antenna on it be consistent with the shape of the aircraft where it is installed. This is the so-called conformal antenna. In addition to various fixed beam antennas used on modern aircraft, there are also some phased array antennas whose beams can be controlled and scanned. There are two types of phased array antennas: active and passive. Among them, the active phased array antenna generally arranges the antenna array elements as radiators according to certain rules, and cascades T / R components with transceiver circuits behind each ante...
