Problems solved by technology

Since the antenna protrudes from the surface of the carrier, it may affect the aerodynamics of the carrier
Moreover, there are strict requirements on the size, strength and environmental adaptability of the antenna, which greatly limits the application of the air traffic control response antenna on different aircraft platforms.

Embodiment

[0020] Embodiment An airborne response antenna

[0021] Such as figure 1 Shown: an airborne response antenna, the response antenna includes a radio frequency cavity 1 , a radome 2 , a radiator 3 and a radio frequency socket 4 . The radio frequency cavity 1 is made of anti-rust aluminum, and the sunken part at the top is used to connect with the radome 2, and a mounting hole for connecting with the carrier is reserved on the upper edge. The edge portion of the radome 2 is connected with the upper edge of the radio frequency cavity 1 by rivets to protect the internal radiator 3 and the radio frequency socket 4. As a preference, the radome 2 is composed of a hollow shell and a foaming material, and the foaming material is filled Sealed inside the radome 2 to increase the intensity of the radiator. The radiator 3 is an all-metal structure similar to an inverted F shape, which is arranged inside the radio frequency cavity 1. The radiator 3 includes an inverted cone 31, a top disc...

Abstract

The invention provides an airborne response antenna, which includes a radio frequency cavity (1), a radome (2), a radiator (3) and a radio frequency socket (4), and the radome (2) is covered in Above the radio frequency cavity (1), the radiator (3) is arranged inside the radio frequency cavity (1), and the radio frequency socket (4) includes an outer conductor (41) and is arranged inside the outer conductor (41). The inner core (42), the outer conductor (41) is fixed on the outer bottom surface of the radio frequency cavity (1), and the inner core (42) passes through the bottom of the radio frequency cavity (1) and is connected to the lower end bottom surface of the radiator (3). The invention has the outstanding advantages of being conformal to the surface of the carrier platform, compact in structure and small in size.

Description

technical field [0001] The invention relates to the technical field of air traffic management response antennas, in particular to an airborne response antenna. The invention is suitable for air traffic control (ATC) air traffic control radio transceiver system, especially suitable for airborne antenna platforms with conformal requirements. Background technique [0002] With the improvement of aircraft combat effectiveness, higher and higher requirements are put forward for the functional performance, weight and installation size of airborne air traffic control. As an important part of the airborne ATC radio transceiver system, the response antenna is developing towards the direction of integrated aperture, compact structure, and minimized aerodynamic disturbance to the carrier aircraft. [0003] The airborne air traffic control response antenna is usually a vertically polarized omnidirectional antenna, and a monopole antenna resonating in the working frequency band is used ...
