<p><P>PROBLEM TO BE SOLVED: To provide an antenna device capable of obtaining high antenna gain while achieving a side lobe free state (zero-side lobe). <P>SOLUTION: The antenna equipment with two or more antenna elements 1 has a weight operation part 2 for computing a weight vector using weighting function that the antenna pattern to the direction of the outside is made to zero while antenna gain is made to the maximum except to the direction of a center of the main lobe of the antenna pattern and two or more directions in its vicinity, two or more multipliers 3 for carrying out weighting to two or more signals acquired from two or more antenna elements respectively in use of the weight vector computed in the weight operation part, and a synthesizer 4 for synthesizing the output of two or more multipliers. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
