1. An apparatus comprising:
a substrate;
first transmission lines on the substrate, the first transmission lines extending in a first direction from a first side of the substrate;
second transmission lines on the substrate, the second transmission lines alternated with the first transmission lines, the second transmission lines extending in a second direction, opposite from the first direction, from a second side of the substrate that is opposite from the first side;
first antenna elements on the substrate, the first antenna elements coupled to a first of the first transmission lines (a first-first transmission line), the first antenna elements extending in a third direction away from the first-first transmission line; and
second antenna elements on the substrate, the second antenna elements coupled to a first of the second transmission lines (a first-second transmission line), the second antenna elements extending in a fourth direction away from the first-second transmission line and toward the first-first transmission line, the fourth direction opposite to the third direction, the first-first transmission line and the first-second transmission line positioned adjacently on the substrate,
wherein a first distance between the adjacent first-first and first-second transmission lines is different than a second distance between the first-first transmission line and a second of the second transmission lines (a second-second transmission line), the second-second transmission line adjacent to the first-first transmission line on an opposite side from the first-second transmission line, and
wherein at least two antenna elements in the first antenna elements are differently sized.
