1. An antenna, comprising:
a transparent substrate;
a first square patch antenna element with a first square lattice structure deposited on the transparent substrate;
a second square patch antenna element with a second square lattice structure deposited on the same side of the transparent substrate as the first square patch antenna element, the second square patch antenna element being spaced apart from the first square patch antenna element in a first direction; and
a low profile transparent passive decoupling strip deposited on the transparent substrate between the first and the second square patch antenna elements in the first direction,
wherein an optical transparency of the antenna is 83%±0.5%,
the first square lattice structure comprises horizontal conductive wires and vertical conductive wires that cross each other, with both the horizontal conductive wires and the vertical conductive wires equally spaced to form square spaces therebetween,
the second square lattice structure has a structure identical to that of the first square lattice structure,
in the first direction, a size of the low profile transparent passive decoupling strip is less than that of the first square lattice structure or the second square lattice structure, and
in a second direction that is perpendicular to the first direction, a size of the low profile transparent passive decoupling strip is less than that of the first square lattice structure or the second square lattice structure.
