A dipole’s horizontal radiation pattern looks like a figure 8 from above (b). In 3D, the pattern is shaped like a doughnut with maximum radiation perpendicular to the length of the antenna.

If the antenna shapes or focuses the radiation pattern and makes it more directional, it has gain over an isotropic antenna. A dipole has a gain of 2.16 dBi over an isotropic source.

Radiation patterns for antennas can be utterly confusing, especially when presented in two dimensions, as they usually are. Fear not, [Hunter] has your back with 3D printed and color-coded radiatio… ...

Thus, the radiation pattern looks rather like a donut (or a bagel, depending on your nutritional inclinations). The gain of a typical dipole roughly half a wavelength long–16 cm at 900 MHz–is about ...
