<P>PROBLEM TO BE SOLVED: To avoid a complicatedness and an enlargement of a device construction with an antenna array consisting of a plurality of wave guide slot antennas, whose opening is enlarged. <P>SOLUTION: A distributor 30 is equipped with a wave guide for feeding which extends in a direction of widths of the wave guide slot antennas 10A to 10H, and has openings 12 formed on a surface of a wall of the wave guide for feeding, through which wave guides for radiation having the wave guide slot antennas 10A to 10H communicate with the wave guide for feeding. Since the distributor 30 uses the wave guide for feeding of the length same as a summation of widths of the wave guides for radiation having the wave guide slot antennas 10A to 10H, the device construction is not complicated and enlarged even if the opening of the antenna array is enlarged by increasing a number of the wave guide slot antennas which constitute the antenna array. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
