Figure 1-1 A Spatial 3D Pattern. A parabolic reflector, dish, or mirror is a device that is used to collect or project energy such as electromagnetic waves. The antenna gets its name from the crisscross pattern traversed by its single winding of molybdenum-wire, shown in red in the model. It can be clearly understood by the radiation. Using a pattern greatly enhances your planning accuracy as it simulates your hardware's true radiation capability. The spatial radiation pattern of an antenna is typically represented by a three-dimensional (3D) graphic or polar plots of horizontal and vertical cross sections (or planar cuts) of the 3D graph. Finally, the pattern is plated using industry-standard methods where the plating adheres to the plastic only where the plastic has been activated by the laser, thus creating a conductive pattern. The antenna module has three parameters: the gains parameter takes a sequence of gain and angle pairs (given in decibels and degrees), the first pair must be 0 0. Dipoles also have an element pattern in the azimuth plane, resulting in a narrower total antenna pattern, compared with the elevation pattern shown on the next page. These principal plane patterns can be obtained by making two slices through. omnidirectional antenna: An omnidirectional antenna is a wireless transmitting or receiving antenna that radiates or intercepts radio-frequency ( RF ) electromagnetic field s equally well in all horizontal directions in a flat, two-dimensional (2D) geometric plane.

It is important to state that an antenna radiates energy in all directions, at least to some extent, so the antenna pattern is actually three-dimensional. For a reciprocal antenna, these two patterns are identical. The antenna pattern is the response of the antenna to a plane wave incident from a given direction or the relative power density of the wave transmitted by the antenna in a given direction.
