Web briefly, an antenna pattern (or a radiation pattern) shows the intensity of radio waves which the antenna delivers in each direction.

For this reason, radiation patterns are typically displayed on a logarithmic scale rather than a linear scale. The radiation pattern can be shaped by adding directing elements (directors) in front and reflecting elements (reflectors) behind. This letter investigates the impact of antenna radiation patterns in passive radio sensing applications. Planetary and space science, 2016.

Web typical antenna parameters are bandwidth, gain, radiation pattern, polarization, impedance & beamwidth. Note that this picture is only a 2d slice of a 3d pattern. Web mimo antenna design involves various aspects, including array configuration, beamforming techniques, antenna placement, polarization considerations, radiation patterns, diversity gain, isolation techniques, bandwidth support, and simulations.

A pattern may also be defined for a receiving antenna, however, we defer discussion of the receive case to a later section. For this reason, radiation patterns are typically displayed on a logarithmic scale rather than a linear scale. The hga radiation pattern controls echo spectrum shape for surfaces with rms slopes larger than about 2°;
