Claim:
1. A dual band antenna radiating structure, comprising: a first high-band patch radiating element that comprises an electrically conductive plane for radiative coupling with high-band RF energy fed via at least one high-band feed located below the first high band patch radiating element; a second high-hand patch radiating element comprising an electrically conductive plane configured above and spaced apart from said first high-band patch radiating element in a radiating direction, the second high-band patch radiating element comprising a secondary radiating patch; a first low-band patch radiating element comprising an electrically conductive plane configured between the first high-band patch and the second high-band patch, the low-band patch radiating element including an aperture that enables the second high-band radiating element to be radiatively coupled with the first high-band patch radiating element; a second low-band patch radiating element configured below and spaced apart from the first low-band patch radiating element and comprising an electrically conductive plane having an aperture for radiative coupling with low-band RF energy fed via at least one low-band feed that is configured on a dielectric sheet below and spaced apart from the second low-band patch radiating element; and a metallic perimeter structure, configured around the edges of said first and second high-band patch radiating elements, comprising at least first, second and third wall sections extending generally in the radiating direction, none of which wall sections extends generally perpendicular to the radiating direction, wherein said first wall section is configured with one end positioned in close proximity to said first high-band patch radiating element and the other end extending in the radiating direction is oriented away from said first high-band patch radiating element, wherein said second wall section is configured with one end coupled to the first wall section and the other end of said second wall section is oriented generally away from the radiating direction, and wherein said third wall section is configured with one end coupled to the second wall and the other end of said third section is oriented generally in the radiating direction and wherein the metallic perimeter structure has a cross section that is substantially in the shape of the letter “N” to form a continuous N-shaped wall and wherein at least two of the wall sections are angled relative to each other.
