Description
[technical field]
The utility model relates to the communication antenna field, relates in particular to a kind of wide-band shaped antenna cover and comprises the microwave antenna of this wide-band shaped antenna cover.
[background technology]
In point-to-point or the microwave communication network of single-point to multiple spot, microwave antenna is absolutely necessary and receives and the device of electromagnetic signals.Along with the microwave communication growth of requirement, it is more and more intensive that communication network becomes, and it is also increasing to produce the potential risk that interferes with each other between the microwave telecommunication system.
For avoiding or weakening interfering with each other between the microwave telecommunication system; Each executive authorities and Virtual network operator have been formulated strict standard to limit the antenna pattern envelope of microwave antenna, require to select to satisfy the microwave antenna of various criterion grade again according to different communication networks.
Antenna cover is the important composition parts of microwave antenna system, mainly plays two effects: the first, and the influence of protection antenna dust, sleet, natural environment such as freezing; The second, reduce the wind-force load of microwave antenna system, and then alleviate the mechanical performance requirement of antenna installation system.
Therefore, the engineering design target of antenna cover generally include following some:
On electric property, antenna cover can not cause that gain, return loss, antenna pattern envelope and the front and back of antenna are compared etc., and performance index worsen, and the design object of the best of antenna cover is to improve the electric property of antenna;
On mechanical performance, antenna cover need have advantages such as structural strength is good, volume is little, the wind lotus is little;
Aspect cost, the cost of antenna cover itself and the cost that is installed on the antenna are low.
If the design of antenna cover can't be satisfied above-mentioned engineering design target, then can produce following harmful effect to the electric property of antenna:
Lost antenna gain; This insertion loss of mainly being introduced by antenna cover causes; Not only to select low-loss dielectric material when therefore requiring the designing antenna outer cover, also want the thickness of appropriate design antenna cover, thereby make antenna cover have good wave beam through performance;
Increased the return loss of antenna, promptly worsened the standing wave ratio of input voltage of antenna, this mainly is to be come back to due to the feed by the reflection electromagnetic wave that the antenna cover structure causes itself;
Influenced the antenna pattern envelope performance of antenna; Performance is compared in the front and back of especially having worsened antenna; This is because antenna cover has upset due to the diffraction field at antenna reflective face edge distributes; When situation is serious, antenna cover even can produce the back to the diffraction field and act on to " guiding ", thus caused the backward radiation of antenna.
The antenna cover of existing microwave antenna adopts single layer structure mostly, and mainly comprises three kinds of versions: plate shaped, spirogyrate and concave shaped.Simultaneously, the manufactured materials of existing antenna cover selects generally that quality is even, dielectric constant stable and the low dielectric material of loss for use.Yet the antenna cover of above-mentioned existing single layer structure can't satisfy above-mentioned electric property design object fully, and is higher such as its bad mechanical property and cost.The shortcoming of the antenna cover of these three kinds of existing single layer structures is described respectively below.
The antenna cover of plate shaped single layer structure adopts thickness to be about the dielectric material of half dielectric material wavelength usually, thereby makes antenna cover obtain wave penetrate capability preferably, and then reduces the influence of antenna cover to gain and standing wave ratio of input voltage.Yet, not enough below the antenna cover of this plate shaped single layer structure exists:
At first, frequency-bandwidth limited, thereby can't be applied to the broadband microwave antenna system;
Secondly because the marginal portion of the antenna cover of existing plate shaped single layer structure handles without special figuration usually, therefore to the antenna pattern envelope of antenna, especially before and after than harmful effect is greatly arranged;
At last, the mechanical strength of the antenna cover of plate shaped single layer structure itself is relatively poor.
Though the antenna cover of concave shaped of the prior art or spirogyrate single layer structure can obtain the frequency bandwidth characteristics of broad through certain cone angle design, these structures often reckon without antenna pattern envelope especially front and back are compared Effect on Performance; In addition, the mechanical strength of the antenna cover of concave shaped single layer structure and wind lotus performance are not good.And; Though obtained the frequency bandwidth characteristics of broad through the design of cone angle; But generally about 15%, it is the user demand of the microwave antenna of 6～40GHz such as requiring bandwidth that this relative band width still can't satisfy bandwidth requirement higher to its relative band width usually.
In addition, for working frequency range for for the microwave antenna of the microwave antenna of low-frequency range especially 6～10GHz, the antenna cover of traditional single layer structure; No matter adopt plate shaped, spirogyrate, or concave shaped; Since need carry out structural design according to half medium wavelength, thus cause the thickness of antenna cover bigger, its weight thereby also bigger; Especially in, bigbore antenna cover; Even surpass the weight of entire emission face assembly, cause the entire antenna system load bigger, simultaneously its manufacturing cost and whole Transporting cost also increase thereupon.Correspondingly, the microwave antenna of this antenna cover being installed also bears similar shortcoming with not enough.
Therefore be necessary to provide a kind of improved antenna cover, especially wide-band shaped antenna cover and microwave antenna are so that overcome shortcoming of the prior art with not enough.
