Note: If you trying to align a table column (left, center, or right) use Template:Table alignment. This is a generic template for handling the horizontal alignment of elements on a page. Use the template like this:
The radiation patterns of a vertical half-wave dipole, an omnidirectional antenna.The horizontal and vertical polar patterns are projections of the 3 dimensional pattern onto horizontal and vertical planes, respectively.
The electric field or "E" plane determines the polarization or orientation of the radio wave. For a vertically polarized antenna, the E-plane usually coincides with the vertical/elevation plane. For a horizontally polarized antenna, the E-Plane usually coincides with the horizontal/azimuth plane. E- plane and H-plane should be 90 degrees apart.
A simple template to center-align content in tables and other places. Be aware that the center class is applied to this template, which means every element within the template has its left and right margins set to auto. This may harm some templates.

In radio propagation, horizontal plane is used to plot an antenna's relative field strength in relation to the ground (which directly affects a station's coverage area) on a polar graph. Normally the maximum of 1.000 or 0 dB is at the top, which is labeled 0 o, running clockwise back around to the top at 360°. Other field strengths are ...
What effect a parasitic element has on the radiation pattern depends both on its separation from the next element, and on its length. The driven element of the antenna is usually a half-wave dipole, its length half a wavelength of the radio waves used. The parasitic elements are of two types.
It is one example of what the International Telecommunication Union refers to as "mixed polarization", i.e. radio emissions that include both horizontally- and vertically-polarized components. [14] In the United States, Federal Communications Commission regulations state that horizontal polarization is the standard for FM broadcasting, but that ...
Animation showing how a phased array works. It consists of an array of antenna elements (A) powered by a transmitter (TX). The feed current for each element passes through a phase shifter (φ) controlled by a computer (C). The moving red lines show the wavefronts of the radio waves emitted by each element.
