Active antenna system and signal processing module

TLDR: In this article, the authors propose an active antenna system and a signal processing module which allow for simple and short-time recovery work in the case of failure, where the antenna body includes an antenna housing section 71 where the multiple antenna elements are housed, a module housing section 72 placed on the opposite side to the antenna housing Section in the transmission reception direction of the radio signals, and capable of housing a prescribed number of signal processing modules.

Abstract: PROBLEM TO BE SOLVED: To provide an active antenna system and a signal processing module which allow for simple and short time recovery work in the case of failure.SOLUTION: An active antenna system includes an antenna body 5 internally provided with multiple antenna elements 6 and multiple antenna elements, and multiple signal processing modules 10 attached detachably to the inside of the antenna body, and processing radio signals transmitted and received by the multiple antenna elements. The antenna body includes an antenna housing section 71 where the multiple antenna elements are housed, a module housing section 72 placed on the opposite side to the antenna housing section in the transmission reception direction of the radio signals, and capable of housing a prescribed number of signal processing modules, and a prescribed number of connectors placed on the antenna housing section side in the module housing section, and where a prescribed number of signal processing modules are arranged toward the transmission reception direction. The module housing section is open so that the signal processing modules can be put in and out from the directions excepting the transmission reception direction and the opposite direction thereof.SELECTED DRAWING: Figure 8
