NFC Antenna: Background, Performances, Advantages, and Disadvantages

If you want to exchange data within your digital devices, the NFC antenna is there to help you. It connects the devices situated at the nearest position.

In this modern era, there’re endless NFC-compliant devices, including NFC-powered wallets, mobile phones, data loggers, etc.

Perhaps, that’s why people are getting more and more interested in using NFC antennas, its performances, and real-world uses.

Look, we’ll go through almost everything regarding the NFC antenna and its uses. Let’s continue our article to learn everything regarding the NFC antenna.

Structure of NFC Antenna

The NFC antenna transfers the maximum power and reasonable frequency whether you have an active or passive device. The near-field communication is actually a coil inductor that creates a parallel resonant LC tank to transfer maximized power.

For forming the parallel resonant LC tank and transferring the maximum power, the NFC combines a capacitor to the ground. Shortly, the NFC antenna forms a resonant-tuned circuit combining the coil and capacitor.

NFC performances: It’s all in the Antenna

The NFC provides sufficient power and frequencies for starting and running the device smoothly. 

The frequency of the NFC antenna stays within 13.56 MHz, and the rate ranges between 106kbit to 424kbit. Honestly, the frequency ranges and performances of NFC antennas depend on the size of your device.

Undoubtedly, the performance of the small NFC-powered devices is slower than the more significant NFC-powered devices. That means you’ll get low frequencies and slow services if you’re a small device like a smaller smartphone.

However, some high-frequency NFC antennas deliver an overall good performance and operating volume.

Advantages of NFC Antenna

The use of NFC antennas has become trendy for its multiple advantages. Life has become simpler and more cost-effective because of using NFC-engaged devices.

We want to share the advantages of using NFC-powered devices with you.

Easy Transaction

The NFC antenna helps to complete the transaction easily with the pre-installed wallet app on your device. You’ll just get the wallet app and enable the NFC reader on your device.

Booking and Reservation

Whether it comes to reserving or pre-booking your room at a hotel, you can easily do it by enabling the NFC antenna to your device. Not only these, but the NFC tag also allows you to pre-book the tickets, but entry/exit also passes, redeems, and many more.

Helpful to Customers and Enterprises

Customers and enterprises get the NFC antenna helpful to make their transactions. When customers and enterprises are connected with the same Antenna, they don’t need to use hard cash for the transaction.

The customers can make their payment through the NFC-powered device, and the enterprise can receive it. There’s no risk of fraud, like getting fake cash.

Essential for Students and Employees

When the students and employees are within their respective campuses, they badly need a device interconnection. When the employees are connected with each other through the NFC antenna, they can easily share their important documents and information securely.

Similarly, when campus students are inter-connected with their NFC-compiled devices, they can share their important notes and studies at no cost.

Require No Additional Thing for Connectivity

While using the NFC-compiled device, you’ll not need to pair up your device through connectivity like Bluetooth. You can establish a secure connection with multiple devices by enabling the NFC tag, unlike Bluetooth.

Opening the Bluetooth in your device, you can make a connection only within 2 single devices.

No Need for Special Software

Using the additional software makes the system operation complicated. The NFC tag doesn’t need any special software to establish the connection.

Therefore, using the NFC tag in your NFC-compiled device is not so complicated. Honestly speaking, there’s simply an NFC switch in your phone settings for almost every modern device.

Disadvantages of NFC Antenna

To prove your idea wrong, we also have figured out some disadvantages of the NFC antenna. Let’s look at those facts before establishing the NFC connection in your device.

Limited to The Shorter Ranges

The NFC, which stands for Near field communication, connects the devices within short ranges. You can connect the devices within 10 to 20 cm using the NFC antenna.

Time-consuming Method

The NFC antenna can’t provide faster data transactions; hence, establishing the NFC connection to a highly commercial area is unwise. The data transferring rate of the NFC antenna ranges between 106 to 424.

So, it’s wise to establish the network in a place where faster communication isn’t compulsory.


Data transmission through the NFC network is expensive to many companies because of its lower data transmission. Besides, not all devices are NFC-compiled, so it becomes expensive for many companies to ensure NFC-powered devices for all employers.

Complex Procedures

Although it doesn’t need to install any software to use NFC, still, it’s more complicated to operate than some other options. Therefore, if you want your employer can properly use NFC tags, you must train them first; that’s costly.

Not So Risk-Free at All

Mobile-based hacking keeps NFC-powered devices at risk, although it’s considered a completely risk-free option. Needless to say, hackers have become advanced in hacking any simple devices.

Higher Power Consumption

NFC-enabled devices consume more power than simple devices. Shortly, this is another way that NFC devices increase the overall costs of enterprises.


What Is an NFC Antenna?

The NFC refers to Near Field communication that helps to transmit data to NFC devices with the RFID antenna. The technology is successfully designed to establish communication through standard smartphones.
The unique features of the NFC antenna are its loop structure and operation at low frequencies.

How Big Can NFC Antenna Be?

Understanding the length of the NFC antenna is important to check or test its performance of the NFC antenna. The measurement of the NFC antenna ranges between 7cm*2.5cm.
Alternatively, the NFC antenna measurement shouldn’t exceed 10cm.

What Frequency Does NFC Use?

Near-field communication technology supports short-distance devices at a high frequency. The frequency range of NFC tags and NFC readers stays within 13.56 MHz.

Where is the iphone nfc antenna

After the 6 versions, the iPhone has NFC chips to read the NFC tags. If you have the older version of the iPhone, you must get the NFC sensor on its backside.
Check the NFC sensor at the center, the lower or upper portion of your older iPhone.

For the newer version, the NFC tag should be in the setting of your iPhone. Just select the setting app, enter into the control center. There you’ll find a green plus button of the NFC Tag reader that you’ll need to tap to enable the NFC tag.

How Much Data Can an NFC Tag Hold?

The data-storing capacity of an NFC tag depends on its memory construction. The NFC tag with simpler construction and memory can store more than 100 bytes of data.

Typically, the memory capacity of the NFC tag ranges between 48 bytes to 1 megabyte.

What Does NFC Mean on My Phone?

The NFC helps to transfer and share data to NFC-powered devices from different simple devices. NFC, or Near field communication, has evolved from radio frequency identification, but it’s more expanded than RFID.

How Do You Use NFC On Android?

The NFC works on NFC-powered devices, including mobiles, data loggers, payment readers, wallets, etc. You must enable the NFC on your android before using the technology.

To enable the NFC on android, enter the “Setting” option in the first step. Secondly, select “connected device” and “Connected preferences.”

Right after that, you must get the NFC and contactless payment that you must tap in. Your NFC antenna is activated and ready to use.

What Causes Poor Signal Strength?

The following factors can cause poor signal strength to your NFC antenna connection.
1. Adverse weather.
2. Distance from the nearest cell center.
3. Network overload.
4. Different sorts of Terrain.
5. Multiple interferences from different building materials.

How Important Is NFC In A Phone?

The benefits of using the NFC in your phone are many; some of those benefits are:

1. The NFC technology helps the user to make a secure transaction through their android device.
2. e technology helps to exchange digital content.
3. The NFC allows connecting multiple electronic devices with a single touch.

The Sum Up!

Eventually, the NFC antenna has both advantages and drawbacks. But the drawbacks are ignorable if you genuinely want to use NFC-powered devices to save your time and money.
