Abstract
Description




FIG. 1 is a top left front isometric view of a shaped reflector surface of a microwave antenna showing our new design, the top right front isometric view being a mirror image thereof;




FIG. 2 is a top rear right isometric view thereof, the top rear left isometric view being a mirror image thereof;




FIG. 3 is a front elevational view thereof;




FIG. 4 is a rear elevational view thereof;




FIG. 5 is a right side elevational view thereof; the left side elevational view being a mirror image thereof;




FIG. 6 is a top plan view thereof;




FIG. 7 is a bottom plan view thereof;




FIG. 8 is a cross-sectional view taken along line 8—8 of FIG. 6;




FIG. 9 is a cross-sectional view taken along line 9—9 of FIG. 6;




FIG. 10 is a cross-sectional view taken along line 10—10 of FIG. 6;




FIG. 11 is a cross-sectional view taken along line 11—11 of FIG. 6; and,




FIG. 12 is a cross-sectional view taken along line 12—12 of FIG. 6;




The broken lines in the Figures are for illustrative purposes only and form no part of the claimed design. The thickness of the lines in FIGS. 8-12 is for illustrative purposes only and does not limit the claim to a particular thickness. The surfaces that are not shown in the drawings or described in the specification form no part of the claimed design.



Claims
  • The ornamental design for a shaped reflector surface of a microwave antenna, as shown and described.
