Intelligent antenna device supporting multiple network types

Abstract

The invention discloses an intelligent antenna device which supports a plurality of network types. The main content of the invention includes: a combination port of a first combiner is connected with a first oscillator of a configured first antenna array; a combination port of a second combiner is connected with a second oscillator of a configured second antenna array. The second oscillator and the first oscillator are identical in horizontal position. A first shunt port of the first combiner and a first shunt port of the second combiner are connected with two shunt ports of a first power splitter respectively. A combination port of the first power splitter is connected with a multi-type antenna port through a phase-shift network. The first power splitter enables the shapes of output horizontal-plane direction wave-beam patterns meet the coverage demands of signals of a plurality of kinds of network types through determination of the amplitudes and phase positions of downlink signals output by the first oscillator and the second oscillator so that under a condition that the prior intelligent antenna structure is not changed, coexistence of the signals of the plurality of types of networks is realized and thus resources for system construction are saved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a smart antenna device supporting multiple network standards. Background technique [0002] With the development of mobile communication technology, in addition to the second-generation Global System for Mobile Communications (2GGSM) network and the third-generation time-division synchronization code division multiple access technology (3G TD-SCDMA, etc.) network under construction, it is about to enter The era of the fourth generation Time Division Long Term Evolution (4G TD-LTE) network. However, a large number of customer bases supporting 2G and 3G networks will exist for a relatively long period of time. Therefore, multiple communication network standards will coexist in the existing communication network system. [0003] At present, multiple network operators have network systems of 2G and 3G standards. Considering the application of 4G networks, antenna resources will b...
