2.4 GHz and 5GHz Wifi Panel Antenna: What are the Differences?

06 Jun, 2023

When you look through the communication industry, you may find most panel antenna products tend to have the label "2.4 GHz", "5GHz", and "5.8 GHz". And, do you know what it means and what are their differences? In this post, the author would guide you to explore these secrets.

What’s the Meaning of the GHz?

GHz is the abbreviation of the gigahertz, which is a unit of measurement for frequency in the International System of Units (SI). The hertz (Hz) is the base unit for frequency, and the prefix giga- indicates multiplication by one billion, so GHz represents one billion cycles per second.

Is There A Difference Between 2.4 GHz and 5GHz Wifi Panel Antenna?

There are four main differences between the 2.4GHz panel antenna and the 5GHz wifi panel antenna ---- interference, device compatibility, range, and bandwidth.


In the interference, the 2.4 GHz band is more susceptible and is more easily get interference by the devices such as Bluetooth, devices, microwaves, etc. Then, the 5GHz wifi panel antenna is not easily get affected, the 2.4 GHz band tends to be less congested.


Although most modern wifi devices support both 2.4 GHz and 5 GHz frequencies, some older devices or IoT (Internet of Things) devices may only support the 2.4 GHz band. Therefore, if you have older or less capable devices, using a 2.4 GHz WiFi panel antenna would ensure compatibility.


As for the range and bandwidth, on the one hand, the 2.4 GHz panel antenna covers further distances but may perform at faster data rates. On the other hand, the 5GHz wifi panel antenna tends to cover a shorter distance at faster data rates.

What Frequency is 2.4 GHz Panel Antenna?

A 2.4 GHz panel antenna is designed to operate at the frequency of 2.4 gigahertz (GHz). This frequency falls within the 2.4 GHz ISM (Industrial, Scientific, and Medical) band, which is a globally available unlicensed frequency band.

Will A 2.4 GHz Antenna Work for 5 GHz Wi-Fi?

No, a 2.4 GHz antenna will not work for 5 GHz Wi-Fi. The reason is that 2.4 GHz and 5 GHz are different frequency bands within the wireless spectrum, and each requires a corresponding antenna designed specifically for that frequency range.

A 2.4 GHz antenna is optimized for the 2.4 GHz frequency band and is designed to transmit and receive signals within that specific range. It is not designed to operate at a higher frequency of 5 GHz.

In summary, the answer of the “will a 2.4 ghz antenna work for 5ghz”  is no.

On the other hand, a 5 GHz antenna is specifically designed to operate within the 5 GHz frequency band. It is engineered to transmit and receive signals within that frequency range and is optimized for the characteristics of the 5 GHz spectrum.


The frequency bands have different properties, including range, signal penetration, and interference characteristics. Therefore, using a 2.4 GHz antenna for a 5 GHz Wi-Fi network would result in poor performance, reduced signal quality, and limited range.


To ensure optimal performance, it is important to use an antenna that is specifically designed for the frequency range of the Wi-Fi network you are using. For a 5 GHz Wi-Fi network, a dedicated 5 GHz antenna should be used to achieve the best results.

Is There A Way to Convert 5GHz to 2.4 GHz?

No, it is impossible to directly convert a signal from 5 GHz to 2.4 GHz or vice versa in a single mode of the wifi panel antenna. The 5 GHz and 2.4 GHz frequencies are separate and distinct frequency bands within the wireless spectrum, and they operate using different physical properties and technologies.


If you need to use a device or network that operates on a different frequency band, such as switching from a 5 GHz Wi-Fi network to a 2.4 GHz Wi-Fi network, you can consider using compatible devices and antennas designed for the specific frequency. For example, you can purchase a 2.4/5GHz panel antenna to change the frequency band between 2.4G and 5G.


All in all, when you plan to purchase the wifi panel antenna, you need to know what kind of band your project plan to use and pay attention to the parameter in the wifi panel antenna. If want to get a wifi panel antenna that can both work at the 2.4GHz and 5 GHz, a 2.4/5GHz panel antenna could be the ideal option.
