Problems solved by technology

[0005] It can be seen that the wiring methods of the above-mentioned omnidirectional antennas all need to use additional wires, the wiring is complicated, and the three pairs of vibrators are mutually independent vibrators, and a mixer needs to be configured to mix the signals
In addition, the traditional antenna is exposed to the vibrator, and the air filling between the vibrators affects the impedance of the vibrator. In the environment where the wind speed, air pressure, and air composition change outdoors, a stable impedance cannot be guaranteed, thereby affecting the quality of the received signal.

Embodiment 1

[0024] figure 1 It is a front view of an embodiment of the antenna of the present invention, an omnidirectional television receiving antenna, comprising a support plate 1 of plastic material and two vibrator pieces 2 staggered from each other on the upper and lower sides of the support plate 1 (the vibrator piece 2 on the back side Not shown), the vibrator piece 2 is star-shaped, the vibrator piece 2 includes a connection port 22 in the center of the vibrator piece 2, and 3 vibrator units radiating from the connection port 22 at an equal angle, the vibrator unit includes one end connected to the connection port 22 The conduction part 24 of the conduction part 24, and the radiation part 26 connected with the other end of the conduction part 24, and the two connection ports 22 are connected with the coaxial cable.

[0025] The support plate 1 is provided with a positioning post 12 for fixing the vibrator piece 2 on the support plate 1 . Buckles can also be provided on the suppo...

Embodiment 2

[0028] image 3 It is a perspective view of the vibrator piece of this embodiment. The difference between this embodiment and Example 1 is that the support plate is an equilateral triangle, one vibrator piece contains 3 vibrator units, and the conductive parts of adjacent vibrator units are separated by 120 degrees. Divide the triangle into 3 equal parts. The radiating part is linear, and the length is about 1 / 2 of the side length of the triangle. The corresponding two conduction parts are located on the perpendicular of the same side of the triangle, and the corresponding two radiation parts respectively extend from the vertical foot to the two vertices of the side.

Embodiment 3

[0030] Figure 4 It is a perspective view of the vibrator piece of this embodiment. The difference between this embodiment and Example 1 is that the support plate is a square, and one vibrator piece contains 4 vibrator units, and the conduction parts of adjacent vibrator units are separated by 90 degrees. Divide the triangle into 4 equal parts. The radiating part is linear, and the length is about 1 / 2 of the side length of the square. The corresponding two conduction parts are located on the perpendicular of the same side of the square, and the corresponding two radiation parts respectively extend from the vertical foot to the two vertices of the side.

[0031]To sum up, under the guidance of the concept of the present invention, in addition to the above-mentioned embodiments, it is also possible to design a variety of vibrator pieces and corresponding support plates with different specifications. Wired and impedance stabilized.

Abstract

The invention relates to the field of wireless communication, and especially relates to an omnidirectional television receiving antenna. The omnidirectional television receiving antenna comprises a support disk and an oscillator, wherein the oscillator is connected to a signal processor through a coaxial cable; the oscillator comprises two oscillator sheets mutually staggered on the upper and lower surfaces of the support disk; the oscillator sheets are star-shaped; each oscillator sheet comprises a connection port in the middle of the oscillator, and multiple oscillator units radiating with equal angle from the connection port; and two connection ports are connected with the coaxial cable. The antenna provided by the invention simplifies wire connection, and also saves a mixer generally used in a multi-oscillator group scheme, so that the cost is saved.

Description

technical field [0001] The invention relates to the field of radio communication, in particular to an omnidirectional TV receiving antenna. Background technique [0002] An antenna is a component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, rely on antennas to work. With the popularity of wireless digital TV signals, more and more people receive TV signals outdoors or on the move, not just indoors. To receive TV signals outdoors, especially while moving, because the signal tower is fixed, and the position of the receiving antenna is constantly changing, it is necessary to use an omni-directional receiving antenna to ensure better reception. [0003] The prior art discloses an omnidirectional television receiving antenna, which includes ...
