<P>PROBLEM TO BE SOLVED: To accomplish a radome which is capable of widening vertical directivity. <P>SOLUTION: A radome 10 comprises an outer wall 11 of which a side cross section is semicircular and an inner wall 12 which is disposed inside of the outer wall 11. The inner wall 12 includes a first inner wall 211 and a second inner wall 212, and the first inner wall 211 is disposed at a fixed interval dc with respect to the outer wall 11 within a range from a midpoint Pc on a circumference of the outer wall 11 to a position of a predetermined distance toward both ends Pe in a side view. The second inner wall 212 has one end connected to an end portion of the first inner wall 111, and is comprised of a plate having a plane parallel to a straight line connecting the midpoint Pc and a center Po. Thus, an interval de between the outer wall 11 and the inner wall 12 in the vicinity of the end portion Pe of the outer wall 11 becomes wider than the interval dc between the outer wall 11 and the inner wall 12 in the vicinity of the midpoint Pc of the outer wall 11. <P>COPYRIGHT: (C)2012,JPO&INPIT |
