Directional Antennas

What are the features of directional antennas?

Radiation characteristics of directional antennas

Directional antenna signals are concentrated towards a specific direction of emission, the directionality is very strong. In this particular direction, the signal strength is large and spreads over a long distance, but the signal is weak or absent in other directions. Similar to the beam of a flashlight, it has obvious directionality.

Directional antenna gain

Directional antennas are more likely to have a high gain, usually above 9dBi. By focusing the signal in a specific direction, directional antennas have greater signal strength in that direction, enabling signal transmission over longer distances.

Directional antenna applications

Directional antennas are suitable for long-distance communication, such as point-to-point wireless transmission and satellite communication. It is also often used in street coverage and cell coverage, which can reduce interference to other areas and improve the utilization rate of the signal.

Price and cost of directional antenna

Directional antennas may cost more than omnidirectional antennas due to their relatively complex design and manufacturing process. However, in scenarios with high requirements for signal quality and transmission distance, directional antennas are more cost-effective.

What are the types of directional antennas?

The directional antennas include Yagi-Uda antennas, dish antennas, horn antennas, roop antennas, panel antennas, sector antennas, parabolic antennas, grid parabolic antennas, etc.
