Antenna.
Background technology
With the rapid development of mobile communication technology, often require that array antenna can not only cover in antenna for base station construction
Multiple frequency ranges are covered, and the system that a variety of wireless standards can be supported.But base station resource is limited, construction cost is huge, integrates
The antenna of multiple multiple standards of frequency range turns into required.Generally when designing double frequency or multifrequency antenna for base station, if different frequency range
Frequency interval it is very big, such as frequency range (790-960MHz) and frequency range (1710-2170MHz), at this moment, the coupling between two frequency ranges
It is right relatively low, realize good isolation and directional diagram performance with common a period of time can.But due to frequency range and standard
Variation, different working forms is also had between successive bands.And once the frequency interval of two kinds of radio bands is close, such as
Frequency range (790-862MHz) and frequency range (880-960MHz), intercoupling between alien frequencies antenna element is very big, can only pass through increasing
Add the spacing between two units to be intercoupled to reduce, increase the isolation of port.And the spacing between adding unit causes
Bigger antenna size, heavier antenna weights, higher construction cost.
In engineering application, the closely spaced frequency range of design frequency (790-862MHz) and frequency range (880-960MHz) day
Line, conventional method have two kinds, first, an array is formed with the antenna element for covering whole frequency range (790-960MHz), preceding
One duplexer of end cascade, is realized between two working frequency range by designing the duplexer of high-isolation high out-of-side rejection effect
Independent communication.However, duplexer will necessarily bring cascade loss and insertion loss, the gain of antenna is influenceed, and due to frequency
Section is close, and the duplexer of design filter with low insertion loss high-isolation has very big challenge.In addition, this kind of scheme is only used only one
Individual array, therefore independent electricity can not be carried out to each frequency range during WLAN optimizes and adjusts angle of declination.Second
Method is using the subarray parallel arranged for being operated in two frequency ranges (790-862MHz＆880-960MHz) respectively, in two sons
Uncoupling network is added between array, so as to reach the effect of uncoupling.However, these uncoupling networks can increase aerial array

In the prior art, there is scholar to propose to will be operate in the antennas of two frequency ranges and carry out double frequency day by way of embedded
The design of line, but because antenna element does not have a filtering characteristic, coupling is stronger, frequency multiplication or bigger frequency interval can only be carried out
Dual-radio design.Also scholar utilizes the mode of filtering a period of time parallel arranged of two frequency ranges, it is proposed that one kind can be close in frequency
In the case of realize dual frequency array, realize preferable isolation, but the area taken is larger.
