Other numerical value between 85mm, 90mm, 95mm or 85-95mm.
Fig. 1 to Fig. 3 is combined again, and chamfered section 3 can be equipped between the side wall of the polypropylene cover body 1 and the cover 2, it is described
3 one end of chamfered section connects the side wall of the polypropylene cover body 1 close to the side of first opening portion 11, described in other end connection
Cover 2.The size of chamfered section 3 can according to 2 size of cover, the first opening size, the size of antenna 100, antenna 100 performance need
The decisions such as ask so that 100 meet demand of antenna.Optionally, the radius of the chamfered section 3 can be 10 ± 5mm, for example, chamfered section 3
Radius can be between 5mm, 10mm, 15mm or 5-15mm other numerical value.In a specific implementation, the first opening portion
11 a diameter of 100mm, a diameter of 110mm of the second opening portion 12, a diameter of 90mm of cover 2, the radius of chamfered section 3 are
10mm is provide with antenna 100, directional diagram, transmitting and the reception gain of antenna 100 using the antenna house 200 under the dimensional configurations
It is optimal.
In addition, in the present embodiment, side wall, the cover 2 and the chamfered section 3 of the polypropylene cover body 1 be one into
Type, the structural stability of antenna house 200 is strong.Certainly, in other embodiments, the side wall of the polypropylene cover body 1, the lid
Body 2 and the chamfered section 3 can respectively be connected by bonding or other modes, alternatively, the side wall of the polypropylene cover body 1 and described
Chamfered section 3 is integrally formed, and the cover 2 is connected with the chamfered section 3 by bonding or other modes, alternatively, the cover 2
It is integrally formed with the chamfered section 3, the side wall and the chamfered section 3 of the polypropylene cover body 1 are connected by bonding or other modes
It connects, but the structural stability of antenna house 200 obtained under these combinations is poor.
Since the thickness of antenna house 200 is bigger, the loss of electromagnetic wave and reflectivity are bigger, 100 plane of direct interference antenna
The formation of wave, leads to Sidelobe degradation.The thickness of the side wall of the polypropylene cover body 1 of the present embodiment can be according to heat dissipation performance, antenna 100
Performance requirement etc. because usually setting.Optionally, the thickness of the side wall of the polypropylene cover body 1 can be 0.5 ± 0.2mm.Wherein,
± 0.2mm is the admissible error range of thickness of the side wall of polypropylene cover body 1, facilitates the processing of polypropylene cover body 1.It is preferred that
Ground, the thickness of the side wall of polypropylene cover body 1 is 0.5mm, smaller on the influence of 100 performance of antenna, and rapid heat dissipation.
Further, the madial wall of the polypropylene cover body 1 is additionally provided with fixed part 4, for connecting the antenna 100.
In one embodiment, the fixed part 4 is screw thread, and the madial wall of the polypropylene cover body 1 and the pedestal of the antenna 100 pass through spiral shell
Line coordinates.In other embodiments, the fixed part 4 or clamping portion, the clamping portion is connected to the bottom of the antenna 100
On seat, so as to which polypropylene cover body 1 is fixed on 100, antenna.
Fig. 4 is 100 unused antennas cover 200 of antenna and the E faces using polypropylene antenna house 200 in a preferred embodiment
Directional diagram, at this point, polypropylene antenna house 200 is smaller on the performance influence of antenna 100, and dust-proof effect is preferable.Fig. 5 to Fig. 6 is
100 unused antennas cover 200 of antenna and the E faces directional diagram using polypropylene antenna house 200.From figs. 5 and 6, it can be seen that make
After the polypropylene antenna house 200 of the utility model, antenna 100 realizes 360 ° of omnidirectionals of single direction and uniformly scans, antenna
100 gain, beam angle, secondary lobe can be met the actual needs.From figs. 5 and 6, it can be seen that polypropylene antenna house
200 is thinner, the performance of antenna 100 is influenced smaller.In addition, polypropylene antenna house 200 is thinner, the more heat dissipation conducive to antenna 100.
But in view of the dust-proof effect of polypropylene antenna house 200, the thickness of polypropylene antenna house 200 should not be too thin, needs to consider
The dust-proof effect and polypropylene antenna house 200 of polypropylene antenna house 200 are dissipated to 100 performance of antenna and polypropylene antenna house 200
The thickness because usually setting polypropylene antenna house 200 such as thermal effect.Certainly, antenna 100 is not limited to 360 ° of uniform scannings, can also
Scanning for discrete angular or other angles range.Fig. 7 is 100 unused antennas cover of antenna and the use of thickness is 0.5mm glass
The E faces directional diagram of glass steel antenna house, and with reference to fig. 4 to fig. 6, it can be seen that use the antenna 100 of polypropylene antenna house 200
Performance is more preferably.
It is noted that the antenna house 200 of above-described embodiment can be applied to arbitrarily with antenna 100 equipment (for example,
Radar system) in, antenna 100 is protected by antenna house 200, the service life of extension antenna 100.Following embodiment will
It is further illustrated so that antenna house 200 is applied to radar system as an example.
Compared with ultrasonic wave, infrared and laser radar etc., it is stronger that millimeter wave penetrates cigarette, mist, the ability of dust, has whole day
Wait round-the-clock the characteristics of, thus millimetre-wave radar be widely used in the various industries such as automobile, traffic, security protection, industry, unmanned plane and
Smart machine.With the diversification of application scenarios, the testing the speed of single radar, angle measurement, ranging are had been unable to meet compared with complex environment
The demand of the equipment of lower work, multitask, multifunction demand increasingly increase, in addition to radar Back end data processing complication,
Beam scanning can be carried out by also needing to radar antenna, detect different direction.Realizing the mode of beam scanning has mechanical scanning and electronics
