Abstract
The invention discloses a copper sheet type slot omnidirectional antenna. The antenna comprises a first radiating sheet, a second radiating sheet, a third radiating sheet, a medium substrate, a bottom plate, a fixing plate, a feeder line and a copper sheet, wherein the first radiating sheet is vertically orthogonal to the second radiating sheet; a slot line is formed between the first radiating sheet and the third radiating sheet; the first radiating sheet and the third radiating sheet are arranged on the medium substrate; the third radiating sheet is connected with the bottom plate; the fixing plate is arranged below the bottom plate; the feeder line passes through the bottom plate and the fixing plate and connected with each radiating sheet; the first radiating sheet is vertically orthogonal to the second radiating sheet to form four regions of which one region is provided with one circular arc copper sheet; and the two ends of the copper sheet are connected with the two side edges of the first radiating sheet and the second radiating sheet respectively. In the omnidirectional antenna, one circular arc copper sheet is welded between the two radiating sheets for adjusting characteristic matching and standing-wave ratio, so the radiant gain and omnidirectional characteristic of the antenna are optimized.
Description
Technical field
The present invention relates to a kind of communication antenna, relate in particular to a kind of slot type omnidirectional antenna that transmits and receives radio signal, belong 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 objective of the invention is in order to overcome the deficiencies in the prior art, copper sheet type slot type omnidirectional antenna is provided one.
The technical solution used in the present invention is: one copper sheet type slot type omnidirectional antenna, 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 provided with one copper sheet in one of them zone, 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 present invention can be used for body of rod diameter.
Beneficial effect: the present invention has welded the circular arc copper sheet one 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.
