An antenna having an essentially non-directional pattern in azimuth, and a directional pattern in elevation.
Antenna that radiates equal power in all directions in a horizontal plane.
An antenna that can pick up signals from all directions; i.e., it doesn't have to be pointed directly at the source of the signal to pick it up. Typically this type of antenna is used when the specific direction of the signal is not known, when one antenna is receiving and transmitting in several directions (as in a repeater station in an RF network), or for mobile applications.
An antenna for wireless equipment which sends or receives a propagated radio signal in all directions simultaneously. This differs greatly from a directional antenna which is only capable of sending or receiving information on the same axis as the corresponding antenna on the other end. Omni-directional antennas are great for short range broadcasts because of their versatility. However, high gain directional antennas are recommended for most long range wireless video applications.
an antenna that produces a constant field strength in azimuth (horizontal), but that can have a directional radiation pattern in elevation (vertical)
There are several types of antennas that are used in an RF implementation. Omni-directional antennas are among them. Omni-directional antennas radiate an RF signal in a 360 degree pattern.
An antenna which radiates RF energy in a 360 degree patterns about an axis.
A transmitting aerial in which the energy radiated by a radio or TV station is transmitted uniformly in all directions.
An antenna with a radiation pattern that, when viewed from above, is equally strong in all directions.
An antenna which is capable of line-of-sight communication with a satellite without requiring any pointing. Generally used on an Inmarsat C MES.
