Abstract
Technologies directed to terminated bridge elements between panel gaps are of an antenna structure are described. The antenna structure includes a first circuit board, a second circuit board, and a structure. The first circuit board includes a first set of antenna elements. The second circuit board includes a second set of antenna elements. The structure is located over a gap between the first circuit board and the second circuit board. The structure includes an antenna element. The antenna element, an antenna element of the first set of antenna elements, and an antenna element of the second set of antenna elements form a lattice pattern.
