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...

The radiation-field pattern can be calculated by applying Huygens' principle in a similar way to a rectangular aperture. The electric field pattern can...

half of the dipole, which adds to the direct radiation to form a dipole radiation pattern. So the pattern of a monopole with a perfectly conducting, infinite...

needed] The dipole is any one of a class of antennas producing a radiation pattern approximating that of an elementary electric dipole with a radiating...

in the medium. Also known as the radiation-zone, the far field carries a relatively uniform wave pattern. The radiation zone is important because far fields...

and reception.[citation needed] Large loop antennas have a two-lobe radiation pattern at their first, full-wave resonance, peaking in both directions perpendicular...

field radiation pattern of an antenna or other radiation source, that are not the main lobe. The radiation pattern of most antennas shows a pattern of "lobes"...

zero on the axis. When graphed in three dimensions (see graph) this radiation pattern is often described as doughnut-shaped. This is different from an isotropic...

center. The pattern of electric and magnetic fields at the aperture plane at the mouth of the horn, which determines the radiation pattern, is a scaled-up...

monopole antenna, and like a vertical dipole has an omnidirectional radiation pattern, radiating equal radio power in all azimuthal directions (perpendicular...
