Embodiment Construction

[0015] In view of the problems in the prior art, the embodiment of the present invention adopts a common antenna method, by setting a TD system antenna array and an LTE (or GSM) antenna array on one antenna device, thereby realizing the shared antenna of the TD system and the LTE (or GSM) system .

[0016] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] See Figure 2A with Figure 2B , Is a schematic diagram of the array layout of the antenna device provided by the embodiment of the present invention. Figure 2A The antenna device shown takes an 8-antenna antenna device as an example. The array of the antenna device is a 6×8 array, that is, the array of elements in the array is arranged in 8 rows and 6 columns, and the columns are sequentially numbered 1, 2, 3, 4, 5, 6 columns. among them:

[0018] The arrays in the second, third, fourth, and fifth columns use radiating elements designed based on the A...

Abstract

The invention discloses antenna equipment shared by multiple systems, which aims to solve the problems of signal loss caused by the introduction of a combiner in the conventional multi-system antenna fusion technology and roof resource shortage. In an antenna array of the antenna equipment, a part of the array is used for receiving and transmitting signals of a fourth generation or second generation mobile communication system, and antenna ports corresponding to the array are used for connecting master devices of the fourth generation or second generation mobile communication system; and in the antenna array of the antenna equipment, the rest part of the array is used for receiving and transmitting signals of a third generation mobile communication system, and antenna ports corresponding to the array are used for connecting master devices of the third generation mobile communication system.

Description

Technical field [0001] The present invention relates to the field of mobile communication, in particular to an antenna device that can be shared by multiple mobile communication systems. Background technique [0002] With the development of mobile communication technology, in addition to the second-generation global system for mobile communication (2G GSM) network and the third-generation time division synchronization code division multiple access technology (3G TD-SCDMA) network under construction, there will be future The fourth generation time division long-term evolution (4G TD-LTE) network. In this case, there will inevitably be a network development situation where multiple communication standards coexist. The current three communication standards have independent antenna feeder systems, and the frequency bands used are also very different. However, at present, because multiple operators have 2G and 3G multi-standard networks, and considering subsequent evolution, the num...
