Abstract

The invention discloses an electrically adjustable directional smart antenna, which is applied to a TD-SCDMA system, and includes: an antenna array, including N (N≥2) longitudinal sub-arrays in the horizontal direction, and each longitudinal sub-array includes at least M (M≥2) radiating units and several groups of power distribution networks, each sub-array shares the reflection base plate and radome; calibration network; several groups of phase shifters; synchronous linkage device; drive unit; scale scale; The antenna also includes a synchronous linkage device, at least one of the groups of phase shifters has a multi-layer structure, and is cascaded connected to the drive unit and the scale scale through the synchronous linkage device; the calibration network is connected to each antenna The subarrays are connected in the same coupling manner. The smart antenna disclosed by the invention can continuously electric downtilt and realize continuous electric regulation.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an electrically adjustable and directional smart antenna with continuous electrical downtilt characteristics used in a TD-SCDMA system. Background technique [0002] Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) technology, as one of the third generation mobile communication (3G) systems, has broad application prospects. As one of the key technologies of TD-SCDMA system, smart antenna has become a research hotspot in the antenna industry. In the TD-SCDMA system, the system performance can be improved by using the smart antenna. Smart antennas can increase coverage distance, reduce initial infrastructure costs, improve link performance, and increase system capacity. At present, the realization method of the smart antenna is to design several longitudinal sub-arrays in the horizontal direction. Each longitudinal sub-array has at least two radiating element...
