This wireless communication device is equipped with: a circuit board including an antenna element; an estimating means for estimating a current distribution in at least a partial area on the circuit board, which is induced by power feeding to the antenna element; and a specifying means for specifying a radiation pattern associated with the current distribution estimated by the estimating means as a radiation directivity of the circuit board. 無線通信装置が、アンテナ素子を含む回路基板と、このアンテナ素子への給電により誘起される回路基板上少なくとも一部領域の電流分布を推定する推定手段と、この推定手段により推定された電流分布に応じた放射パターンを前記回路基板の放射指向性として特定する特定手段と、を備える。 - 特許庁
To provide an incoming radio wave direction estimating antenna system with which the real time processing of incoming direction estimation and antenna directivitypattern control to a moving object moving near a base station at high speed is enabled, high-reliability data transmission is performed and reduction of interference to the other base stations or mobile stations or transmission power drop reduction is enabled. 基地局の近傍を高速に移動する移動体に対し、到来方向推定及びアンテナ指向性パターン制御の実時間処理を可能とし、高信頼性のデータ伝送を行い且つ他の基地局や移動局への干渉や送信電力の低減が可能な電波到来方向推定アンテナ装置の提供を目的とする。 - 特許庁
