What is a Folded Dipole Antenna?

Understanding the essence of folded dipole antennas can be challenging for most individuals due to their technical aspects. Thankfully, in this post, we are going to cover everything about this popular wireless solution in an easy-to-understand language. Here, we’ll talk about what the folded dipole antenna is, including its types, advantages, and disadvantages. That will give you a clear picture about it and you can make a better decision when selecting an antenna for you.

What is a Folded Dipole Antenna?

A folded dipole antennas is generally known for its impedance properties. They can be identified by the additional parallel elements joined at both ends. Its elements are folded to form a cylindrical closed shape. With this unique physical appearance, the device is called a folded dipole antenna.

This wireless solution is ideal for establishing consistent communication between long distances. It effectively transmits and receives electromagnetic waves from different places without losing the quality of the signals. You can see these antennas integrating as a signal entity. But sometimes they are also used in other antennas to increase the performance of the entire system.

Key Features of Folded Dipole Antenna

Folded dipole antennas are well-known wireless solutions in various industries. It comes with extensive capabilities and features that increase its popularity among users. Today, as there are so many wireless solutions, folded dipole antenna stands apart from the rest due to its specific characteristics. Let's talk about some of the key features to understand more about this device:

Frequency Range

The half-wave dipole antenna can transmit and receive a broad spectrum of frequencies. They can work within a frequency range of 3KHz to 300GHz. This ability makes it a flexible solution for situations where maintaining good performance and less sensitivity is critical. For example, it is especially used in television receives.

Omnidirectional Antenna

A folded dipole antenna is an omnidirectional antenna. It facilitates 360-degree coverage to share and receive signals in all directions. That makes it ideal for applications where uniform signal distribution in all directions is paramount. Its folded design provides an efficient signal transmission in all directions. The coaxial dipole antenna plays an essential role in applications like broadcasting, wireless networking, and communication systems.

High Gain

They are mainly designed to deliver high-gain signal strength. It has a typical gain of around 2.15dBi (decibels over isotropic radiator) which is effective enough for long-range distances. The side mount dipole antenna is a better solution for areas with weak signals. In such locations, they provide improved signal strength and share and receive signals with less interference.

Radiation Pattern

The radiation pattern of folded dipole antennas is similar to a simple dipole. Both emit radio waves in a shape that resembles the number eight. They transmit and radiate signals equally well in all directions perpendicular to their length.  The omnidirectional radiation pattern of antennas ensures consistent signal transmission in all directions.

Applications

Folded dipole antennas are an effective device for long-range communication. These wireless solutions are used in applications like telecommunication. They act as a feeder element in the Yagi antenna and contribute to signal transmission.  Furthermore, the folded dipole antenna can also use in the VHF antenna and UHF communication systems to make reliable communication between two points.
