In the field of antenna design the term radiation pattern (or antenna pattern or far-field pattern) refers to the directional (angular) dependence of the strength of the radio waves from the antenna or other source.

Radiation Pattern. The energy radiated by an antenna is represented by the Radiation pattern of the antenna. Radiation Patterns are diagrammatical representations of the distribution of radiated energy into space, as a function of direction. Let us look at the pattern of energy radiation.

2022年9月12日 · The radiation pattern of a transmitting antenna describes the magnitude and polarization of the field radiated by the antenna as a function of angle relative to the antenna. A pattern may also be defined for a receiving antenna, however, we defer discussion of the receive case to a later section.

2015年2月10日 · To better understand antenna gain, antenna designers utilize two dimensional, and three dimensional patterns to aid in proper antenna selection. These patterns provide system engineers a visual of how a specific antenna radiates.

The radiation pattern of typical antennas are presented. The concept of radiation patterns are introduced, also known as antenna patterns. Isotropic, omnidirectional, and directional radiation or power patterns are described.

2024年3月21日 · An antenna radiation pattern is a fundamental concept in antenna theory that visualizes how an antenna radiates energy into space. The radiation pattern is essential for determining the antenna’s performance and identifying the areas of maximum signal strength.

The radiation pattern or antenna pattern is the graphical representation of the radiation properties of the antenna as a function of space. That is, the antenna’s pattern describes how the antenna radiates energy out into space (or how it receives energy).

2016年10月12日 · The radiation pattern of an antenna gives us information about its receiving and transmitting properties in different directions. The radiation pattern can be shaped by adding directing elements (directors) in front and reflecting elements (reflectors) behind.

Common parameters or definitions in regards to radiation patterns are presented. These include beamwidth, half power beamwidth (HPBW), and sidelobes.

Measuring an antenna's radiation pattern and gain is discussed. The general idea and necessary steps are indicated. The idea of planar cuts (such as E-plane or H-plane) are introduced for measuring 3D radiation patterns.
