Abstract
A reflective panel for deflecting electromagnetic waves comprised of a resistive material varying in resistivity across the panel; a center portion on the panel, having a predetermined resistivity; a periphery portion on the panel having a higher resistivity than the center portion; and wherein the center portion of the panel is adapted to reflect the electromagnetic waves and wherein the periphery portion is adapted to minimize diffractions.
Claims11
A system for deflecting electromagnetic waves, comprising:
- a reflective panel comprising:
- a flat resistive panel varying in resistivity across the panel;
- a center portion on the panel, having a resistivity;
- and
- a periphery portion on the panel having a higher resistivity than said center portion, wherein said center portion of said panel is adapted to reflect the electromagnetic waves, wherein said periphery portion is adapted to minimize diffractions;
- wherein said reflective panel has line of sight communication capability with a first antenna, said reflective panel additionally having line of sight communication capability with a second antenna, wherein said first antenna does not have line of sight communication capability with said second antenna.
A method for directing electromagnetic waves to a second antenna, said method comprising the steps of:
- providing a reflective panel, said reflective panel comprised of:
- a flat resistive panel varying in resistivity across the panel;
- a center portion on the panel, having a resistivity;
- and
- a periphery portion on the panel having a higher resistivity than said center portion, wherein said center portion of said panel is adapted to reflect the electromagnetic waves, wherein said periphery portion is adapted to minimize diffractions, wherein said reflective panel has line of sight communication capability with a first antenna, said reflective panel additionally having line of sight communication capability with a second antenna, wherein said first antenna does not have line of sight communication capability with said second antenna;
- and
- placing the reflective panel in a predetermined position relative to said first antenna to deflect the electromagnetic waves to said second antenna.
A system for deflecting electromagnetic waves, comprising:
- a reflective panel, said reflective panel comrpising:
- a flat resistive panel varying in resistivity across the panel;
- a center portion on the panel, having a resistivity;
- and
- periphery portion on the panel having a higher resistivity than said center portion, wherein said center portion of said panel is adapted to reflect the electromagnetic waves, wherein said periphery portion is adapted to minimize diffractions;
- wherein the reflective panel is placed behind an interfering antenna to reduce back radiation, and wherein the reflective panel is positioned in a predetermined position to deflect the back radiation to a desired wireless sector.
A method for directing electromagnetic waves to a predetermined location, said method comprising the steps of:
- providing a reflective panel, said reflective panel comprised of:
- a flat resistive panel varying in resistivity across the panel;
- a center portion on said reflective panel, having a resistivity;
- and
- a periphery portion on the panel having a higher resistivity than said center portion, wherein said center portion of said panel is adapted to reflect the electromagnetic waves, wherein said periphery portion is adapted to minimize diffractions, wherein said reflective panel is placed behind an interfering antenna to reduce back radiation, and wherein the flat reflective panel is positioned in a predetermined position to deflect the back radiation to a desired wireless sector;
- and
- placing the reflective panel in a predetermined position relative to said interfering antenna to deflect the electromagnetic waves to the predetermined location.
