Problems solved by technology

[0007] The present invention aims at the antenna array caused by the two-level structure of "sector-beam" existing in the existing three-plane array beam switching smart antenna, which needs to use phase shifters (that is, delay lines with different lengths), complex PIN switch arrays, and each beam Inconsistency and other defects provide a beamforming and switching method based on a centrosymmetric regular polyhedron, especially a regular polygonal prism smart antenna

Abstract

The invention relates to a method for forming wave beam and switching wave beam, based on positive polyhedral intelligent antenna, which uses the annular antenna array formed by positive polyhedral, uses the logic control circuit to decode the instruction sent by superior machine, and sends the decoded signal to the driving circuit; the driving circuit based on said decoded signal generates relative driving signal, to drive the radio switch to connect or cutoff relative transmission feedback wire and connected antenna; the radio signal can reach connected micro antenna unit, to be interfered superposition, to form same-phase wave beam at normal direction of external round of positive polyhedral. The invention can avoid phase-shifter or delay line, while the array and circuit are symmetry.

Description

technical field [0001] The invention relates to a beam forming and switching method of an intelligent antenna system, in particular to a beam forming and switching method based on a regular polyhedron intelligent antenna device. Background technique [0002] In wireless communication antenna systems, smart antenna systems are mainly divided into four categories: sectorized antenna systems, beam switching antenna systems, beam forming antenna systems and diversity antenna systems. Among them, the "intelligence" level of the sectorized antenna system and the beam switching antenna system is low, and the ability to increase the user capacity and improve the communication quality of the wireless communication system is limited, but these two systems are low in cost and easy to implement . The "intelligence" level of the beamforming antenna system and the diversity antenna system is relatively high, and it is a hot spot in the field of smart antenna technology research. At pres...
