Omni Antennas

Omni antennas, or omnidirectional antennas, are a type of antenna that radiates radio waves in all horizontal directions equally. This means they can receive and transmit signals in a 360-degree pattern, which makes them ideal for scenarios where the exact direction of the desired signal is not known, or when a broad coverage area is needed.

These antennas come in various designs, but dipole antennas are one of the most common types. A half-wave dipole antenna, for example, has a length of about half the wavelength of the radio waves it's designed to communicate with. This type of omni antenna has a radiation pattern that is symmetrical in the horizontal plane, meaning it radiates equally in all horizontal directions.

Low gain omnidirectional antennas are common in applications like home WiFi routers and indoor wireless devices, where the goal is to provide a uniform signal in all directions. On the other hand, high gain omni antennas can capture signals from a greater range and are often used for outdoor applications, such as in cellular networks or for wireless communication in large open spaces.

The leaky wave conductor is a "wireless cable" which acts as an antenna and radiates over the entire length. The range is limited here. Track-guided systems can thus be properly supplied even under complex conditions.
