Description

Foldable Assembly Z-type Antenna

technical field

The utility model relates to a foldable assembled Z-type antenna.

Background technique

In recent years, with the vigorous development of digital TV (Digital TV, DTV) technology, it has been favored by consumers. In response to the trend, the industry has continuously launched new wireless digital TV products.

Digital TV is different from the previous analog TV in that it digitizes the transmission of images and sounds, which in turn brings many obvious benefits to consumers. The aspect ratio of traditional analog TV is 4:3, and the format of digital TV is 16:9, which is more in line with human eyes and closer to the effect of cinema; the resolution of traditional analog TV is only 480i, while the highest resolution of digital TV can be Up to 1080i, bringing consumers a more pleasing picture; and in terms of sound processing, digital TV adopts the Dolby Digital system, allowing consumers to enjoy the same effect as in a movie theater at home.

The digitization of image/sound transmission also has several technical advantages. First, the use of frequency spectrum is more efficient, and more programs can be transmitted in the same bandwidth. The digital video broadcasting system can also overcome the phenomenon of poor or intermittent reception caused by terrain and surface features in the existing analog system, and provide programs with higher picture quality and better sound quality.

However, most general digital TVs use built-in antennas. Due to the limited internal space of digital TVs, the strength of wireless signals is easily affected. To do a good job, you must first sharpen your weapon, and you must use an external antenna to increase the receiving strength and distance.

Therefore, there are those in the industry who have further improved the above problems. As shown in Patent Document 1 below, it is a digital TV antenna, which includes: an antenna body; a base on which the antenna body is fixed, and the cross-section of the base larger than the antenna body; and a ring body set fixed on the upper end of the antenna body for adjusting the size of the cross-sectional area of the antenna body.

Patent Document 1: China Taiwan Patent Announcement No. M307203 "Digital TV Antenna", announcement date March 01, 2007.

The aforementioned patent document 1 has the following problems:

1. The reception strength of the antenna body is limited, and it cannot be changed in real time according to the signal strength. It is easy to have problems that the reception is too weak or some channels cannot be received. In view of this, how to effectively make the antenna change in real time according to the strength of the signal, and at the same time enhance the effect of receiving the signal, has become one of the purposes of this invention.

2. UHF antennas (bandwidth: 470-890MHz) are generally required for wireless digital TVs, and the receiving frequency range of the antenna body can only be used within this range, and cannot cope with the VHF antenna frequency bands used by traditional TVs today. (Bandwidth: 174-220MHz), which cannot meet the needs of consumers who want to watch other channels. In view of this, how to effectively increase the frequency band range of the antenna and combine the receiving frequency band ranges of the VHF antenna and the UHF antenna becomes the second purpose of the present invention.

3. The receiving frequency range of the antenna body must be larger. In order to strengthen the strength of the wireless signal, the antenna body is bound to become larger, and it is extremely inconvenient for consumers to carry and store it. In view of this, how to effectively increase the frequency band range of the antenna and make it convenient for consumers to carry and store becomes the third purpose of the present invention.

4. The manufacturing process of the antenna body is relatively complicated, and the cost of production and materials is high, which greatly increases the commercial cost of the industry and increases the burden on consumers. In view of this, how to effectively increase the frequency band range of the antenna and reduce the cost of the operator and the burden of the consumer becomes the fourth purpose of the present invention.
