Radiation Patterns
Radiation patterns provide information about the directionality and 3-dimensional gain performance of the
antenna by plotting gain at specific frequencies in three orthogonal planes. Antenna radiation patterns are
shown in Figure 7 using polar plots covering 360 degrees. The antenna graphic at the top of the page
provides reference to the plane of the column of plots below it. Note: when viewed with typical PDF viewing
software, zooming into radiation patterns is possible to reveal fine detail
