<P>PROBLEM TO BE SOLVED: To provide a small antenna device capable of receiving an electric wave having a frequency lower than an electric wave of a satellite broadcast, and capable of receiving the electric wave of the satellite broadcast. <P>SOLUTION: An antenna device has an opening 3a formed in a reflecting mirror 3 of a parabolic antenna 1 for receiving a satellite broadcast, and a dipole antenna 2 for receiving an UHF broadcast within the opening 3a. The direction of the dipole antenna 2 is adjustable by rotation support members 8 and 9. Therefore, both the satellite broadcast and UHF broadcast can be received, and downsizing of the device can be achieved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
