摘要
 A slim television broadcast receiver employing antennas in
which a waveguide is formed by a metallic plate and a copper
foil on a printed circuit board. An insulating magnetic
element is loaded so as to block one of a pair of aperture
planes of the waveguide, and the aperture area is enlarged by
beveling the other aperture plane.
 Tuning elements are provided on opposed sides with respect
to the center part of the other aperture, which antennas are
placed on opposed side ends of the slim television broadcast
receiver, thereby performing electronic tuning and phase
synthesis diversity reception.

 In FIG. 1, a digital television broadcast receiving antenna 100
includes a waveguide 104 that is formed by a metallic plate
101 and a copper foil 103 on a printed circuit board 102. A
main aperture plane 107 is provided at the front of the
waveguide 104, and a rear aperture plane 105 is provided at
the back of the waveguide 104

 As shown in FIG. 2, an
insulating magnetic
element 106 is loaded in
the waveguide 104, to
block the rear aperture 105
which is selected from the
main aperture 107 and the
rear aperture 105

The present invention is useful in realizing a slim digital
television broadcast receiver which enables to provide digital
television broadcasting in a free position indoors, without the
need of an external antenna or an indoor antenna jutting
outside, which is connected via a cable, and an external
device for receiving broadcast waves and relaying or
retransmitting the waves to the receiver, at low cost.
