<P>PROBLEM TO BE SOLVED: To provide an antenna device capable of receiving an electromagnetic wave having a frequency higher than that of UHF broadcast and an electromagnetic wave of the UHF broadcast with a high gain. <P>SOLUTION: The antenna device comprises: a planar antenna 1 for satellite broadcasting reception; a bottom board 2 provided by opposing a rear face of the planar antenna 1; a dipole antenna 5 for UHF broadcast reception; and a rotation support member 7 and bolt 9 which rotatably support the dipole antenna 5 against the bottom board 2, and fix a direction of the dipole antenna 5. Therefore, by adjusting the direction of the dipole antenna 5, the electromagnetic wave of the UHF broadcast can be received with the high gain. <P>COPYRIGHT: (C)2012,JPO&INPIT |
