Abstract

The invention relates to an antenna oscillator provided with a metal sheet. The metal sheet is in a closed rectangular ring-like structure, two oscillator arms are arranged in the closed rectangular ring-like structure and are in a symmetric isosceles trapezoid shape, a gap and a space is remained between the two oscillator arms, and two feeding points are respectively arranged at the upper bottom parts of the isosceles trapezoid bodies of the two oscillator arms. The antenna oscillator manufactured by adopting the invention benefits the solution to the problems of narrower band, large manufacturing area, high cost, poor digital signal receiving effect of a traditional television receiving antenna, not only has the characteristic of greater broadband, but also has the advantages of simple structure and low cost.

Description

A kind of antenna oscillator
Affiliated technical field
The present invention relates to a kind of antenna oscillator.
Background technology
The common TV reception antenna of Xiao Shouing in the market, the volume of its antenna oscillator is bigger, frequency band is narrower, the output voltage standing-wave ratio is higher, when receiving digital television signal, reflection loss loss is bigger in the signals transmission, has influence on effective reception of digital signal, and in use mosaic phenomenon is more serious.As traditional planar inverted L or F antenna,, influence its application in the broadband of TV signal because of having intrinsic narrow bandwidth.In addition, be ZL200920031754.8 at number, name is called in the patent of " a kind of wideband dipole symmetrical antenna oscillator ", discloses a kind of antenna oscillator, is provided with the trapezoidal oscillator arms of two symmetries on root, and leaves the slit between two oscillator arms; Though this antenna oscillator has adopted dipole arm, has realized GSM/CDMA, PHS, 3G, the broadband of WLAN frequency range, distributing point is single and asymmetric, causes its width of cloth to penetrate decreased performance.And, cause antenna volume big, incompatibility flat tv machine demand owing to be connected with oscillator arms by root.
Summary of the invention
It is little to the purpose of this invention is to provide volume, and has a kind of antenna oscillator of bigger broadband character.
The technical scheme that the present invention takes is: a kind of antenna oscillator, has a sheet metal, two oscillator arms on sheet metal are the isosceles trapezoid of symmetry, leave slit and space between two oscillator arms, and the upper base place in the isosceles trapezoid of two oscillator arms is provided with two distributing points respectively, it is characterized in that this sheet metal inside is the straight-flanked ring structure of closed, two oscillator arms are positioned at the straight-flanked ring structure of this closed.
Described a kind of antenna oscillator, the following base angle of the isosceles trapezoid of oscillator arms are 45 degree.
The antenna oscillator that adopts the present invention to make, solved traditional tv reception antenna frequency band narrower, make the problem that area is big, cost is high, the receiving digital signals effect is relatively poor, not only have bigger broadband character, have characteristics simple in structure, with low cost again.
Description of drawings
Fig. 1 is a schematic diagram of the present invention.
Sequence number is represented among the figure: oscillator arms 1, straight-flanked ring 2, distributing point 3, slit and space 4.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
Be stamped to form by a sheet metal with reference to Fig. 1, this antenna oscillator, this sheet metal has the straight-flanked ring 2 of closed, two oscillator arms 1 are positioned at the straight-flanked ring 2 of this closed, two oscillator arms 1 are the isosceles trapezoid of symmetry, leave the last bottom that slit and space 4, two distributing points 3 are arranged on the isosceles trapezoid of two oscillator arms 1 between two oscillator arms 1.In order to increase band bandwidth better, the following base angle θ of the isosceles trapezoid of two oscillator arms 1 can be designed to 45 degree.
By above-mentioned design, owing to adopt the distributing point of the oscillator arms 1 and the symmetry of symmetry, both can reduce the cross polarization level in the antenna oscillator H plane, can alleviate the distortion that the width of cloth is penetrated figure in the E plane again, simultaneously, the straight-flanked ring 2 of closed can enlarge active area effectively, improve the width of cloth and penetrate performance, therefore, show that according to test result the range of receiving of the best of this antenna oscillator covers the 470MHz～860MHz frequency range of whole TV signal uhf band, and the characteristic of signal selective reception is preferably arranged, interference signal beyond can the elimination frequency band has guaranteed the quality that signal receives.
