Problems solved by technology

[0002] The ordinary TV receiving antenna currently on the market has a large volume of the antenna vibrator, a narrow frequency band, and a relatively high output voltage standing wave. When receiving digital TV signals, the reflection loss is relatively large during signal transmission, which affects digital signals. Effective reception, the mosaic phenomenon is more serious in use
For example, the traditional planar inverted L or F antenna, because of its inherent narrow bandwidth, affects its application in the broadband of TV signals
In addition, in the patent No. ZL200920031754.8, titled "A Broadband Dipole Symmetrical Antenna Vibrator", an antenna vibrator is disclosed. Two symmetrical trapezoidal vibrator arms are arranged on the root, and the two vibrator arms There is a gap between them; although this antenna dipole adopts symmetrical dipole arms to realize the wide frequency band of GSM / CDMA, PHS, 3G, and WLAN frequency bands, the feeding point is single and asymmetric, which leads to the decline of its radiation performance
And because the root is connected to the vibrator arm, the antenna is bulky and does not meet the needs of flat-panel TVs

Embodiment Construction

[0009] The present invention will be further described below in conjunction with accompanying drawing.

[0010] refer to figure 1 . The antenna vibrator is stamped from a piece of metal. The metal plate has a closed rectangular ring 2. The two vibrator arms 1 are located in the closed rectangular ring 2. The two vibrator arms 1 are in a symmetrical isosceles trapezoidal shape. There is a gap and a space 4 between the two vibrator arms 1 , and the two feed points 3 are arranged at the upper bottom of the isosceles trapezoid of the two vibrator arms 1 . In order to better increase the bandwidth of the frequency band, the lower base angle θ of the isosceles trapezoid of the two vibrator arms 1 can be designed to be 45 degrees.

[0011] Through the above design, due to the use of symmetrical dipole arms 1 and symmetrical feed points, it can not only reduce the cross-polarization level in the H plane of the antenna dipole, but also reduce the deformation of the radiation pattern i...

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

technical field [0001] The invention relates to an antenna vibrator. Background technique [0002] The ordinary TV receiving antenna currently on the market has a large volume of the antenna vibrator, a narrow frequency band, and a relatively high output voltage standing wave. When receiving digital TV signals, the reflection loss in the signal transmission process is large, which affects the digital signal. Effective reception, the mosaic phenomenon is more serious in use. For example, the traditional planar inverted L or F antenna has an inherent narrow bandwidth, which affects its application in the broadband of TV signals. In addition, in the patent No. ZL200920031754.8, titled "A Broadband Dipole Symmetrical Antenna Vibrator", an antenna vibrator is disclosed. Two symmetrical trapezoidal vibrator arms are arranged on the root, and the two vibrator arms There is a gap between them; although this antenna dipole uses symmetrical dipole arms to achieve wide frequency band...
