Problems solved by technology

[0005] Third, these large base stations that are exposed to the outside and have multiple antennas lack aesthetic feeling, are not in harmony with the surrounding environment, and cannot meet the beautification requirements of urban environment construction. Therefore, it becomes difficult to increase antennas in more developed areas and improve the construction of base station networks

Embodiment Construction

[0020] refer to figure 2 and image 3 , the present invention is mainly composed of a TD-LTE antenna 1, a GSM900 antenna 2, a GSM1800 antenna 3, a backplane 4 and a radome 5. Among them, the three antennas of TD-LTE antenna 1, GSM900 antenna 2, and GSM1800 antenna 3 are placed on the top of the backplane 4. The combination method is that the TD-LTE antenna 1 is in the front half of the backplane The antennas 3 are placed side by side on the second half of the backplane 4, forming a "pin"-shaped arrangement structure. Leave a certain space between the front and rear antennas. Since the wavelength of the GSM900 antenna is relatively long, there is a strong coupling between the GSM900 antenna, the GSM1800 antenna and the TD-LTE antenna placed side by side. greater than a quarter of the antenna wavelength. The back plate 4 is a rectangular aluminum plate with a width slightly larger than the maximum width of the antenna. The two long sides of this rectangle have trapezoidal ...

Abstract

The invention discloses a three-mode dual-channel antenna for time division-global system for mobile communications-long term evolution (TD-GSM-LTE), which mainly solves the problems that in modern communication, antennas of different systems are large in volume, have complicated structures and are difficult to erect. The three-mode dual-channel antenna is obtained by the integrated design of a TD-LTE antenna (1), a GSM900 antenna (2) and a GSM1800 antenna (3), namely the three antennas are fixed on a rear panel (4), the TD-LTE antenna (1) is positioned at the front half part of the rear panel (4), and the GSM900 antenna (2) and the GSM1800 antenna (3) are arranged at the rear half part of the rear panel (4) side by side, so that a delta-shaped arrangement structure is formed; the rear panel (4) adopts a rectangular plate with step-shaped flanges; a height adjustment block (6) is padded between the three antennas and the rear panel to adjust dipole surfaces of the three antennas to beon the same plane; cable heads of the three antennas are all fixed at the foremost end of the rear panel and are clearly marked; and a general antenna housing (5) is arranged outside the three antennas. The three-mode dual-channel antenna has a steady and compact structure, is convenient to install, and is superior to the requirement of engineering application in electrical indexes.

Description

technical field [0001] The invention relates to antenna technology, specifically, three kinds of broadband dual-polarized antennas are combined into a TDSCDMA-Global System for Mobile Communications-Long Term Evolution TD-GSM-LTE three-mode dual-channel antenna. Background technique [0002] With the development of cellular mobile communication technology, a variety of technical standards have emerged, including the second-generation mobile communication standard GSM, the third-generation mobile communication standard Time Division Synchronous Code Division Multiple Access TD-SCDMA, and the fourth-generation mobile communication standard TD-SCDMA. Mobile communication standard TD-SCDMA long-term evolution TD-LTE and so on. No matter what kind of system is adopted, the cellular structure is the basic method of wireless coverage area design in cellular mobile communication technology. Standard honeycomb structures such as figure 1 shown. The base station based on the cellul...
