PURPOSE:To make it possible to obtain a desired radiation pattern by eliminating disorders of the feed amplitude and phase among X-directional slots by shifting Y- directional electric-power-distributing microstrip lines in position. CONSTITUTION:Electric power, flowing into Y-directional electric-power-distributing microstrip line (a) consisting of microstrip lines 15, 16 and 17 and input-output branch points 18, 19 and 20, is fed to the 1st right and left X-directional electric- power-distributing microstrip lines (b) from input-output branch point 18 by electric-power 2 distribution by way of microstrip line 15. The remaining electric power reaches input-output branch point 19 by way of microstrip line 16 and is then fed to the 2nd X-directional electric-power-distributing microstrip lines (c) as well as at input-output branch point 18. At input-output branch point 20, the 3rd X-directional electric-power distributing microstrip lines 7 are fed similarly. |
