Description
Technical field
The utility model is related to Microwave Technique and Antenna technical field, is related specifically to a kind of applied to small size, weight
The antenna and antenna technology of amount, high low elevation gain demand.
Background technology
At present, on loading platform, particularly on missile-borne platform, space is very small, and requires lightweight, and size is small, more
Important requirement is that low elevation gain is high, because to meet the demand that missile-borne aircraft goes up a slope and declined.
The most frequently used method is to use ceramic composite in the industry, when space is very small, the effect of ceramic composite
It is just very small, and ceramic material seldom apply with missile-borne platform because missile-borne platform needs the impact demand of high intensity
According to traditional circular helix antenna form, size will be most very limited, in Beidou II platform, be passed
The cylindrical screw wire antenna of system can not just be adapted to missile-borne platform at all considerably beyond requirement condition of the missile-borne platform to size.
, will be by very to navigator fix index according to snail form, it is impossible to meet the requirement of low elevation gain
Serious influence.
Utility model content
The utility model purpose is：For above-mentioned problem, a kind of lightweight size is sought after small and have
The antenna that high low elevation gain is asked.
Technical solution of the present utility model is：
Applied to the helical antenna of Beidou II, including it is mounting base (1), circular helix (2), snail (3), defeated
Outgoing interface (4).Wherein, circular helix (2) one end is vertically welded in bottom plate (1) edge, in 90 ° to be uniformly distributed, the other end with
Snail (3) is welded, and snail (3) is realized parallel to mounting base (1), snail (3) using " returning " font.Cylinder
Helix (2) is by four diameters are identical and lift angle identical 1/4 is enclosed spiral copper cash and formed around city, in horizontal plane distribution in 90 °.
The advantage of the utility model compared with prior art is：
Because the utility model employs cylinder spiral and snail simultaneously as radiator, further broadening antenna
Beam angle, low elevation gain is improved, while considerably reducing the volume and weight of antenna.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
1. uniform 90 ° symmetrical circular helixes in the utility model can realize the input signal of the amplitudes such as equiphase,
It is beneficial to later stage decoding process.
2. the utility model technology may apply to the high low elevation gain field of many related needs, it is suitable for that there is height
The communications field of smart technical requirements.
3. the utility model has, processing simple, dependable performance, small volume, production cost is low, good environmental adaptability spy
Point, can be used in needs the Beidou II system field of low-cost and high-performance, and other microwave communication association areas.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Marked in figure：(1) it is circular bottom plate, (2) are that circular helix, (3) are that snail, (4) are output interface.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Case, the utility model is further elaborated.It should be appreciated that specific implementation case described herein is only used to
The utility model is explained, is not used to limit the utility model.
As shown in figure 1, including circular bottom plate (1)；In the upper surface of the circular bottom plate (1) along outer edge perpendicular to circle
Bottom plate (1) sets 4 circular helixes (2)；Circular helix (2) is the constant copper cash of four identical constant diameters, lift angles,
In the horizontal plane in 90 ° of distributions, the upper end welding plane spiral (3) of circular helix, lower end welding output interface (4), in institute
The top for stating circular helix (2) sets 4 rhizoplane spirals (3)；In the bottom of the circular bottom plate (1), output interface is set
(4)。
Below by one specific implementation case be expanded on further bottom plate (1), circular helix (2), snail (3) and
Relation between output interface (4).Bottom plate (1) in the utility model is that φ 50mm, thickness are that 1.0mm is performed according to area,
Installing plate and corresponding installation site are milled out on high-precise numerically controlled milling machine.Fine copper of the circular helix (2) from a diameter of 1mm
Line coiling is formed, and is evenly distributed on the edge of bottom plate (1) and is fallen in and welded with bottom plate (1), helix (2) is highly 15mm, is risen
Angle is 80 °.Snail (3) is the flat helical antenna of a rule, and its size can be according to common plane Spiral antenna designs, this
From spiral away from for 1mm in example, spiral radiation size is 0.8 millimeter " returning " word-lifting formula mode, is the Big Dipper in respective frequencies
During two generation B3 frequencies, snail radiation body length is optimum size when being exactly λ/2.Data according to the present example are tested,
The low elevation gain that can be reached is -2DBi (20 °), and is unable to reach with other forms in so small size so high
Low elevation gain.
Through theoretical and practical proof, the antenna that can ensure that making by above-mentioned relation Selecting All Parameters reaches design requirement.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modifications, equivalent substitutions and improvements made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
