Analog and digital television broadcast signals cover a wide frequency range, for example, a frequency range of 40MHz to about 900MHz can be covered. Alternatively, the size and thickness of the antenna component of the wall mount may be selected to match a desired frequency range, for example, the antenna structure portion may be made of thicker or thinner metal than the rest of the wall mount, or the antenna structure portion may be enlarged relative to the portion of the wall mount that is not used as an antenna. In addition, the antenna structure portion of the wall mount may be made of a different metal than the rest of the wall mount, such as copper.
Television broadcast signals are typically transmitted from transmission towers and travel in all directions. Optionally, the antenna structure is selected for use with a wall mount to optimize reception of a desired frequency. In some embodiments of the invention, multiple designs may be used together to optimize reception.
The television transmission signal has the characteristic of vertical polarization, so that the antenna structure with the vertical polarization characteristic can better receive the signal than the antenna with other characteristics. The antenna having the circular polarization characteristic can receive only half of the transmission intensity of the signal, and the antenna structure having the horizontal polarization characteristic does not receive the signal at all. In addition, good television antennas typically have an impedance of approximately 75 ohms. Impedance can be controlled by adding matching circuitry to the antenna structure for a wall mount, as desired.

Thus, directional antennas of a particular design are used to form antennas that are configured to receive television or radio broadcast signals from a direction perpendicular to the signals blocked by the screen. Thus, the antenna structure is configured to receive signals from the side behind the screen that is not blocked by the screen. Alternatively, the particular arrangement of directional antennas may replace the antenna structures described above (e.g., antenna structures 130, 230, 330, 430, or 530).

Optionally, the thickness may be about 1-5 mm.
In some embodiments of the present invention, the antenna structure 630 is formed by cutting out portions from a flat sheet of material (e.g., a metal sheet) rather than folding metal wire.

Optionally, one or more detectors 760 are attached to the frame 745 to improve antenna gain. Optionally, the probe 760 extends upward from the plane of the antenna frame 745.

Alternatively, frame 745 may be about 0.5-5mm thick.
In an exemplary embodiment of the present invention, the cable 740 is directly connected to the screen or TV converter/receiver without a matching circuit to control the resistance of the antenna, since the antenna structure 730 is sized to match the wavelength of the broadcast signal.
In some embodiments of the present invention, the antenna structure 730 includes an attachment 790 for connecting a cable 740 to the antenna structure 730 and/or connecting the antenna structure 730 to a screen 780.
