Abstract
The utility model relates to a broad band combination aerial placed on an air plane, which is used for realizing air traffic control (ATC) and friend-or-foe identification (IFF). The utility model is composed of a base which is fixed on an air plane body, an input and output socket, a shell which is fixed on the base and leads a feeding circuit to be sealed in, and an aerial inserting and transmitting body. An aerial radiating body is provided with two active aerial radiating bodies with different length, and a passive aerial reflecting body which is fixed on a base plate, wherein, the two active aerial radiating bodies share the input and output socket through the feeding circuit. Because the utility model is provided with the two active aerial radiating bodies, a transmitting and receiving frequency band is widened. The utility model can realize the condition that the ATC and an IFF answering machine share one aerial, which is convenient for adding an ATC answering machine on the existing air plane.
Description
The utility model relates to a kind of aircraft antenna, particularly realizes air traffic control (ATC) and enemy and we identification (IFF) shared airborne broadband combined antenna.
Existing military aircraft generally only is provided with the IFF transponder aerial.Along with development of aviation, air traffic is crowded and busy day by day, and for ensureing airflight safety, it is very necessary that the ATC answering machine is set on military aircraft.But it is big to add a cover ATC transponder aerial workload on existing aircraft in addition, no antenna installation site.For solving this contradiction, adopt ATC transponder aerial and IFF transponder aerial shared, be a scheme preferably.The structure of existing IFF transponder aerial is by the pedestal that is fixed on the casing, profile is the antenna radiator of blade-like fairing, and the input and output socket constitutes, and antenna radiator is three, the centre is the active antenna radiant body, and both sides are respectively passive radiant body and the passive antenna reflectors of guiding into.Because this antenna active antenna radiant body only is the arrowband so it transmits and receives frequency band, can't realize that ATC and IFF answering machine use jointly.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of IFF of realization and ATC answering machine shared, and the airborne broadband combined antenna of broad frequency band is arranged.
Solution of the present utility model is: a kind of airborne broadband combined antenna, comprise the pedestal that is fixed on the body, profile is the antenna radiator and the input and output socket of blade-like fairing, antenna radiator includes source antenna radiant body and passive antenna reflector, active antenna radiant body and high frequency feed circuit link, and receive on the input and output socket, passive antenna reflector and pedestal are rigid attachment, be characterized in that antenna radiator is two active antenna radiant body and passive antenna reflectors that length is different, the shared input and output socket of two active antenna radiant bodies, the high frequency feed circuit is fixed on the pedestal by a housing (4).
Because the utility model has two active antenna radiant bodies that length is different, two emissions of corresponding existence, frequency acceptance band make the entire antenna frequency band form the broadband, and two different frequency bands can be launched respectively.Receive IFF and ATC signal, and all by feed circuit with the input and output socket is last and transceiver links.The effect of passive antenna reflector is that it is formed unidirectional emission, received signal, to strengthen antenna emission, receiving ability.The effect of housing is that feed circuit is fixed, so that feed circuit and active antenna radiant body are conveniently linked, and can play protection to feed circuit.
In the solution of the present utility model, the high frequency feed circuit is a high-frequency feed line, and two active antenna radiant bodies connect on the high-frequency feed line with parallel way, and high-frequency feed line is drawn an end and is connected on the input and output socket.
The utility model advantage compared with prior art: because the utility model is on the profile basis that does not change existing military aircraft antenna, making the active antenna radiant body is two, and with high-frequency feed line make the active antenna radiant body shared one output input socket, two emissions of corresponding existence, frequency acceptance band, widened the antenna frequency band, IFF and ATC signal can be launched, be received to two different frequency bands respectively, realize the shared antenna of ATC and IFF answering machine, can on military aircraft, set up the ATC answering machine easily.
The utility model can further specify in conjunction with the accompanying drawings.
Figure is the utility model perspective view.
The utility model embodiment is as shown in the figure: airborne broadband combined antenna is by the pedestal 5 that is fixed on the body, be fixed on the housing 4 on the pedestal 5, input and output socket 6 and antenna radiator (1,2,3) constitute, wherein high-frequency feed line is sealed in the housing 4, antenna radiator (1,2,3) two is active antenna radiant body (1 in, 2), one is passive antenna reflector 3, passive antenna reflector 3 is fixed on the pedestal 5, two active antenna radiant bodies (1,2) length difference, be fixed on the housing 4, and pass through respectively, high-frequency feed line is connected on the input and output socket 6 and with the signal in the machine launches, the reception instrument links to each other.
Claims (2)
