Description
[technical field]
The utility model relates to the communication antenna field, relates in particular to a kind of microwave antenna and outer cover thereof.
[background technology]
Along with the microwave communication growth of requirement, the communication network of the point-to-point or point-to-multipoint of being made up of microwave antenna is more and more intensive, and it is increasing to produce the potential risk that interferes with each other between the microwave system.For this reason, each executive authorities and Virtual network operator have been formulated strict standard (Radiation Patterns Envelope RPE), have been selected to satisfy the antenna of various criterion grade again according to different network requirements with the antenna pattern envelope that limits microwave antenna.In the electricity function index of antenna, before and after the radiation than (Front-to-BackRatio, F/B) particularly important, be in the design of antenna, focus on consideration.
Radome is the important composition parts in the microwave antenna system, mainly plays double effect: the first, and the protection antenna is avoided the influence of dust, sleet, natural environment such as freezing; The second, the wind-force load that reduces antenna system is to alleviate the mechanical performance requirement of antenna installation system.Therefore the engineering design target of radome generally includes:
1) on electric property, radome can not worsen the performance index such as gain, return loss, RPE and F/B of antenna, and best design object is to improve the electric property of antenna;
2) on mechanical performance, radome need have characteristics such as structural strength is good, volume is little, the wind lotus is little;
3) aspect cost, the cost of radome itself and the fringe cost that is coupled on the antenna are low.
Radome is mainly reflected in the influence of antenna electrical performance:
1) loss antenna gain, this is mainly caused by the insertion loss that radome is introduced, and not only will select low-loss dielectric material also to want its thickness of appropriate design to reach best wave penetrate capability when therefore requiring radome design;
2) increase the return loss of antenna, promptly worsen the standing wave ratio of input voltage (VSWR) of antenna, this mainly is to be come back to due to the feed by the reflection electromagnetic wave that radome causes;
3) influence the RPE performance of antenna, this mainly is because radome makes that the PHASE DISTRIBUTION of antenna actinal surface electric field is no longer even, thereby has raised the nearly secondary lobe or the minor level far away of antenna;
4) worsen the F/B performance of antenna, this mainly is because radome has been upset due to the diffraction field at antenna actinal surface edge distributes, even radome plays the back to the diffraction field and act on to " guiding ", thus the backward radiation that has improved antenna.

1) frequency-bandwidth limited, thereby be not suitable for all channel antenna system;
Therefore 2) because usually without special figuration, there is considerable influence the radome marginal portion to the RPE of antenna especially F/B;
3) mechanical strength of plate shaped radome is relatively poor.
Though the concave shaped radome can often reckon without RPE especially F/B Effect on Performance by certain cone angle design to obtain the frequency bandwidth characteristics of broad; In addition, the mechanical strength of concave shaped radome and wind lotus performance are not good.
The spirogyrate radome can obtain frequency bandwidth characteristics and F/B performance preferably through the design of certain figuration, and mechanical strength and wind lotus performance are also better, but on to the RPE Effect on Performance, and the spirogyrate radome is not produce deterioration at the most, difficultly plays the improvement effect; In addition, the spirogyrate radome can increase the overall dimensions of antenna, thereby increases packing and cost of transportation.
