Abstract
The utility model discloses a four-copper sheet type groove-shaped omnidirectional antenna which comprises a first radiation sheet, a second radiation sheet, a third radiation sheet, a medium substrate, a base plate, a fixed plate, a feeder line and four copper sheets, wherein the first radiation sheet is vertically orthometric with the second radiation sheet; a groove line is arranged between the first radiation sheet and the third radiation sheet which are arranged on the medium substrate; the third radiation sheet is connected with the base plate; the fixed plate is arranged under the base plate; the feeder line penetrates through the base plate and the fixed plate to be connected with each radiation sheet; the first radiation sheet is vertically orthometric with the second radiation sheet to form four regions which are internally and respectively provided with one arc copper sheet; and the two ends of each copper sheet are respectively connected with two side edges of the first radiation sheet and the second radiation sheet. The four arc copper sheets are welded between every two radiation sheets, so that the property match and the standing-wave ratio are adjusted, and the properties of radiation gain and omnidirectional characteristic of the antenna are optimized.
Description
Technical field
The utility model relates to a kind of communication antenna, relates in particular to a kind of slot type omnidirectional antenna that transmits and receives radio signal, belongs to the Wireless Telecom Equipment technical field.
Background technology
Existing antenna product is to design at different working frequency range mostly, stock size and volume are all bigger, the communication system independent design that has nothing in common with each other, can be compatible or compatible degree depend on the bandwidth and the cost of antenna system, and be the directional antenna product mostly.Though broadband omni-directional antenna product few in number is also arranged, complex structure, design is loaded down with trivial details, versatility is poor, the processing cost height, and there is certain defective in performance.For example biconical antenna and single-stage sub antenna with its preferably broadband character obtained widely using, comparatively complicated but it is made, cost is higher, bandwidth can not well satisfy mobile communication (800 ~ 2500MH
Z) demand.Along with radio communication equipment and electronic message unit develop the hot subject that is designed to domestic and international mobile communications industry research of miniaturization, broadband omni-directional antenna towards multifunction, miniaturization, ultra broadband and the friendly direction of coordinating with surrounding environment.It relates to the wideband impedance match technology of antenna, the optimal design of miniature antenna profile, be suitable for the design of the miniature antenna broadband matching network that the different districts signal covers and the technical barriers such as integrated design of multiband common antenna, but the antenna of a plurality of frequency ranges is integrated into a kind of trend that a kind of antenna structure is current technical development, also is the motive force that realizes device miniaturization.Therefore, develop miniaturization, broadband omni-directional antenna simple in structure, with low cost is very necessary.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, four road copper sheet type slot type omnidirectional antennas to be provided.
The technical solution adopted in the utility model is: four road copper sheet type slot type omnidirectional antennas, comprise first radiation fin, second radiation fin, the 3rd radiation fin, dielectric substrate, base plate, fixed head, feeder line and copper sheet, described first radiation fin and the second radiation fin perpendicular quadrature, be the line of rabbet joint between first radiation fin and the 3rd radiation fin, first radiation fin
Be installed on the dielectric substrate with the 3rd radiation fin, the 3rd radiation fin is connected with base plate, fixed head is installed below the base plate, described feeder line passes base plate and fixed head, and be connected with each radiation fin, described first radiation fin and the second radiation fin perpendicular quadrature form four zones, are respectively arranged with copper sheet one in these four zones, copper sheet is a circular arc, and two ends are connected with two sides of first radiation fin and second radiation fin respectively.
As preferably, the width of described copper sheet is 15 millimeters.
As preferably, described copper sheet is arranged on distance first radiation fin and the second radiation fin top, 35 centimeters.
It is that 140 millimeters Lawn lamp beautifies the body omnidirectional antenna that the utility model can be used for body of rod diameter.
Beneficial effect: the utility model has welded four road circular arc copper sheets between two radiation fins, is used for the regulating characteristics coupling and regulates standing-wave ratio, has optimized the performance of aerial radiation gain and omnidirectional's characteristic.
