text: If we lengthen the element so that the antenna is now a 1/2 wave vertical, the antenna will begin to concentrate the signal and the radiation pattern will compress and look more like a doughnut.
text: However omni-directional antennas in real life usually has signal loss on the top and bottom, and the radiation pattern would look more like a doughnut in 3D. In a two-dimensional view, it forms a figure-of-eight pattern in the vertical plane, and a circle in horizontal plane.
