What is an unidirectional antenna?
A unidirectional antenna is designed to transmit or receive radio waves in a specific direction. These antennas are typically used in situations where it is important to focus the antenna's beam in a particular direction, such as in long-distance communication or directional radio navigation.
What makes an antenna directional?
An Omni-Directional antenna radiates and receives the RF energy equally, providing a 360 degree radiation pattern which allows connectivity in all directions. A Directional Antenna has a radius of around 45 to 90 degrees, focusing RF energy in a required direction and limiting connectivity to that particular area.
What is the directional pattern of an antenna?
Directional Antennas
The signal pattern from a directional antenna has a cigar shape, and looks the same from the top as from the sides. This shape is referred to as a lobe. Directional antennas usually have small side lobes, which are typically ignored because they don't do much for a signal.
What is the difference between omnidirectional and unidirectional antennas?
Omnidirectional antennas receive signals equally from all directions. Directional antennas pull in signals better from one direction. In this direction, they can detect a weaker or more distant signal than an equivalent omnidirectional antenna.
What is an example of a unidirectional antenna?
