Problems solved by technology

[0008] The gain of the broadcast beam emitted by the smart antenna is smaller than the gain of the service beam, resulting in a significant difference in the distance covered by the two types of beams, which seriously affects the network performance of mobile communications; for example, a mobile terminal far away from the base station antenna can receive The signal of the business beam, but cannot receive the signal of the broadcast beam, thus affecting the realization of its mobile communication function

Abstract

The invention discloses an intelligent antenna and a motivational method thereof. The intelligent antenna comprises multiple columns of antenna array elements which are parallelly arranged on the same reflecting plate. The multiple columns of antenna array elements comprise a single column of broadcast antenna array elements used for sending broadcast wave beams, and m columns of service antennal array elements used of sending service wave beams. The space between columns d1 of the service antenna array element columns is determined by the wave length of a work center frequency of the antenna array elements, and the space between columns d2 of the single column of broadcast antenna array elements and an adjacent service antenna array element column is larger than d1. Due to the fact that the single column of broadcast antenna array elements is used for sending the broadcast wave beams, compared with the prior art that multiple columns of antenna array elements are used for sending the broadcast wave beams, electromagnetic fields which are counteracted mutually do not exist, weight loss can be avoided, higher gain is obtained, and therefore difference between broadcast wave beam gain and service wave beam gain is reduced, and mobile communication network performance is improved.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a smart antenna and its excitation method. Background technique [0002] Smart antenna is a proprietary technology of TD-SCDMA system, which applies the phased array antenna principle of radar to cellular mobile phone system. Its main function is that it can not only automatically generate beams for tracking moving targets (mobile terminal equipment such as mobile phones) like radar, that is, service beams, which are used for normal business communication with moving targets; Features of the networking environment Generate broadcast beams covering cells for downlink pilots or broadcast channels. It is realized by controlling the excitation power and phase (referred to as "weight") of each array unit (also called antenna array element, or radiation unit) through the system software, and adaptively generates the required parameters for communication effects in different environ...
