Problems solved by technology

In reality, due to the continuous establishment of dense and tall buildings in cities, not only the signal fading is caused by the multipath effect, but also the broadcast environment of mobile communication waves becomes worse and worse, and it also brings some inconvenience to the setting of base stations, especially the need to It is even more difficult to add antennas to the base station, because the public's original concern about electromagnetic radiation safety will be more intense

Embodiment Construction

[0022] Because the GSM base station antenna is an array antenna, which is equivalent to a port of the TD-SCDMA smart antenna. Therefore, the frequency range of the broadband TD-SCDMA smart antenna can be extended down to 1710MHz, and the array antenna of one or several ports can be shared as one or several GSM base station antennas at the same time. The specific implementation can be carried out through a duplexer , the structure shown in Figure 1.

[0023] Referring to Fig. 1, the present invention consists of a TD-SCDMA smart antenna 9 and a duplexer 3 connected in series. The TD-SCDMA smart antenna 9 is a broadband plate antenna composed of 8 rows of broadband antenna feed units. The high-frequency 1880-2400MHz input port 4 of the duplexer is connected with the output port 2 of the TD-SCDMA equipment 1, and the low-frequency 1710-1860MHz input port 6 is connected with the radio frequency output port 10 of the GSM equipment 11 through the radio frequency cable 5, and the ra...

Abstract

The present invention discloses a two-mode broadband base station antenna based on GSM and TD-SCDMA. The said antenna extend the original low frequency end 1880MHz to 1710MHz of TD-SCDMA intelligence antenna band by cooperation of broadband feed cell and broadband feed network, and connect diplexer in series between the input end of TD-SCDMA intelligence antenna and the RF output end of TD-SCDMA equipment, the low frequency input port of diplexer is connected with RF output port of TD-SCDMA equipment, the two-mode of GSM and TD-SCDMA shared on side TD-SCDMA broadband intelligence antenna structure is formed. The present invention not only reduces the total numbers of base station, saves the charge of GSM base station and feed system, but also avoids space electromagnetic disturb of G network and TD network.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a dual-mode broadband base station antenna shared by two systems of GSM and TD-SCDMA. Background technique [0002] The GSM or CDMA base station antenna is a single column array antenna with a frequency range of 1710-1860MHz. TD-SCDMA is a multi-array antenna composed of multiple single-array antennas arranged horizontally. This antenna is one of the three 3G standards approved by the International Telecommunications Union (ITU), and it is China's first international communication standard in a century. The development of the TD-SCDMA industry can have a market size of one trillion yuan like the 2G GSM / CDMA industry. The frequency bands of existing TD-SCDMA antennas are 1800-1920MHz and 2010-2025MHz, which belong to narrowband smart antennas. [0003] With the development of communication technology, wider requirements are put forward for the frequency band range o...
