Embodiment
Below by drawings and examples, the technical solution of the utility model is described in further detail.
The utility model provides a kind of conformal helical antenna, and the conformal helical antenna includes helical antenna elements and antenna carries
Body, helical antenna elements are Archimedian screw structure, and helical antenna elements are attached on antenna carrier, and are total to antenna carrier
Shape.
In the present embodiment, helical antenna elements turn to Archimedian screw structure using flexible material so that are made
Antenna element be also flexible structure, so as to be attached on the antenna carrier of arbitrary shape.
The antenna carrier of the present embodiment, can be any device for using antenna in the prior art, it is used to attach antenna
The antenna carrier surface of unit can be plane or cylinder or spherical structure or the structure of other curved surfaces.
Wherein, the radar wave of the conformal helical antenna uses the people in vertical polarization, horizontal polarization and circular polarisation a kind of
Polarization mode.
Conformal helical antenna of the present utility model, by using the mode of spiral so that there is broadband, broad beam, circle
The characteristics such as polarization, and size is small, in light weight, particularly suitable for interferometer direction finding system and amplitude monopulse system, therefore
It is widely applied in electronic support and ECM receiving system, the design and radiation characteristic of its various structural model are always
Attract attention and study.In addition, a distinguishing feature of pin helical antenna of the present utility model is easily and carrier surface is conformal,
This aeroperformance to high speed carrier platform is highly beneficial.
The structure of the conformal helical antenna of the present invention is described in detail below by way of specific embodiment.
Fig. 1-Fig. 3 shows the structural representation of conformal helical antenna of the present utility model.
If Fig. 1 is the conformal helical antenna that antenna carrier is planar structure, Fig. 2 antenna carrier is cylinder, Fig. 3 antenna
Carrier is sphere.Because helical antenna elements 1 use flexible material, therefore the antenna that can be attached to different structure well carries
On body, i.e. flat plane antenna carrier 2 in Fig. 1, the spherical antenna carrier 4 in cylinder antenna carrier 3 and Fig. 3 in Fig. 2.Meanwhile
Because helical antenna elements 1 are Archimedian screw structure, therefore can be attached to well on antenna carrier.
In one embodiment, by calculating vertical polarization, horizontal polarization and left-hand circular polarization radar wave respectively, irradiation is put down
The RCS in face, cylinder and the conformal helical antenna of sphere, obtained structure show that the dispersion effect of antenna structure is shown
The conformal contribution to reducing radar scattering cross section is related to the polarization mode of radar wave.Vertical polarization is further calculated along spiral day
The result that collimation method changes to RCS during irradiation with frequency understands that the conformal 2GHz in certain frequency band range is arrived
3.7GHz can play a part of reducing radar scattering cross section, and the effect more than 3.7GHz regions outside frequency band range is then failed to understand
It is aobvious.Therefore, in specific frequency band range, the conformal of conformal helical antenna can reduce thunder scattering section, stealthy so as to play
Effect.
In addition, the gain by calculating helical antenna obtains the stealthy effect of the conformal helical antenna using different antennae carrier
Fruit understands that in whole range of observation, the Stealth Fighter of conformal helical antenna is better than plane spiral shell in specific frequency band range
Revolve antenna.And conformal helical antenna can keep the radiation gain of antenna basicly stable in broadband, and improve antenna
Stealth Fighter.
Conformal helical antenna of the present utility model, antenna element is supported into Archimedian screw structure using flexible material,
And it can be deformed with the structure of antenna carrier, it is achieved thereby that antenna and carrier is conformal, reach and ensured day
Improve the purpose of the Stealth Fighter of antenna while line gain characteristic.
Above-described embodiment, the purpose of this utility model, technical scheme and beneficial effect are entered
One step describes in detail, should be understood that and the foregoing is only specific embodiment of the present utility model, is not used to limit
Determine the scope of protection of the utility model, it is all within the spirit and principles of the utility model, any modification for being made, equally replace
Change, improve, should be included within the scope of protection of the utility model.
