Abstract
A multiple antenna apparatus includes a substrate, a first antenna structure, and a second antenna structure. The first antenna structure includes a first metal trace that has a first pattern confined in a first geometric shape and has a near-zero electric field plane. The second antenna structure includes a second metal trace that has a first pattern confined to a second geometric shape. The second antenna structure is positioned on the substrate in substantial alignment with the near-zero electric field plane of the first antenna structure.
