Technical field
The utility model relates to a kind of unipole antenna, relates in particular to a kind of tri-branch multi-frequency plane unipole antenna, belongs to the wireless communication technique field.
Background technology
In the wireless communication field prior art, traditional antenna has only two branches (shown in accompanying drawing one), and its working range is low-frequency range (800/900MHz), and its bandwidth characteristic narrower (shown in accompanying drawing three) is difficult to satisfy the multifrequency requirement in present 3G epoch.Wireless terminal is because the reinforcement of function, and the raising of wireless module integrated level is had higher requirement to antenna---and need wideer operating frequency, and, press for a kind of antenna that can satisfy the multifrequency needs of 3G along with the maturation of 3G technology.
The utility model content
At the technical problem of above-mentioned existence, the purpose of this utility model is: proposed a kind of broadening of realizing frequency, not only can support 2G, 3G can also support the tri-branch multi-frequency plane unipole antenna of standards such as GPS.
Technical solution of the present utility model is achieved in that the tri-branch multi-frequency plane unipole antenna, comprises housing, branch one, branch two, branch three, reveals copper district, feed; Described branch two, branch three are arranged on the both sides of branch one symmetrically; Described branch one, branch two, branch three fuses with described feed, respectively is provided with circuit in described branch one, branch two, the branch three, and described feed is connected with circuit in described branch one, branch two, the branch three; Described dew copper district is arranged on the housing; Described branch one, branch two, branch three are arranged in the housing, and described feed copper rod is inserted in and reveals in the copper district, and can receive outside radio signal.
Described dew copper district is the copper rod of a hollow.
Described feed is a thin real copper rod.
The tri-branch multi-frequency plane unipole antenna of the utility model scheme makes the antenna working range break through to high band (1900/2100MHz) from traditional GSM frequency range (900/1800MHz), can also be implemented in the broadening (1575MHz) on the GPS frequency range. because its simple version, and excellent wireless telecommunications performance, so be widely used in based on CDMA2000, TD-SCDMA, the 3G wireless terminal product (based on wireless network card) of standards such as WCDMA.
