PURPOSE:To reduce the deviation of radiation characteristics by determing the center coordinates of an antenna on an x-y coordinate plane about the length of the base of a cavity resonator. CONSTITUTION:On the x-y coordinate plane, the coordinates of the centers of respective X-type cross slot antennas 1 are (l/2<1/2>, 0), (-l/2<1/2>, 0), (0, l/2<1/2>), (0, -l/2<1/2>), (l.2<1/2>, l/2<1/2>), (l.2<1/2>, -l/2<1/2>), (-2<1/2>.l, l/2<1/2>), (-2<1/2>.l, -l/2<1/2>), (l/2<1/2>, 2<1/2>.l), (-l/2<1/2>, 2.2<1/2>.l), (l/2<1/2>, -2<1/2>.l), (-l/2<1/2>, -2<1/2>.l), (5l/2.2<1/2>, 5l/2.2<1/2>), (5l/2.2<1/2>, 5l/2.2<1/2>), (-5l/2.2<1/2>, 5l/2.2<1/2>), and (-5l/2.2<1/2>, -5l/2.2<1/2>). The vale in said coordinates is an optional value more than the size of the cavity resonator 3.
