Tips for Choosing the Right RFID Antenna

TAG:Tips for Choosing the Right RFID Antenna

The right antenna is essential to any successful RFID implementation. Without a high-quality antenna from the best RFID antenna manufacturer, your RFID solution will not work as expected. As with most technology, RFID requires a proper signal to function. Therefore, it makes sense to choose the right antenna to ensure a successful implementation. In this article, we review important tips for choosing the right RFID antenna. If you’re working with an RFID solution, check this list before making your purchase.

Size Matters

RFID technology can be implemented in virtually any size of card. However, the right size antenna should be used for the right application. For instance, RFID readers must be able to “see” the tiny antenna on the card. Therefore, you need to make sure that the antenna matches the RFID reader’s frequency. For a variety of applications and industries, the right antenna size can vary. For example, healthcare providers need an antenna with a smaller frequency range. Retailers, on the other hand, need a larger antenna with better performance. Therefore, it’s important to know the industry’s requirements.

Know What You’re Looking For

Before making your purchase, you should familiarize yourself with the various RFID antenna types. There are four main types of RFID antennas: the dipole, the loop, the slot, and the patch. Each type has various applications, allowing for a variety of configurations. Since your choice largely depends on the reader you plan to use, we’ll review the most common reader types.

- Dipole Antennas: This is the most common type of antenna. It consists of two dipole elements that are tightly wound around each other.

- Loop Antennas: This type uses an overlapping loop of wire. The magnetic field created by the loop is stronger than that created by a dipole.

- Slot Antennas: This type is similar to a patch antenna but with a wider slot.

- Patch Antennas: This type features a patch of irregularly shaped metal. The metal helps align the magnetic field along a particular path. These types are ideal for shielding and shielding applications.

Don’t Forget About Power Rating

It’s crucial to remember to select an antenna with the right power rating. The standard for power rating is watts per square centimetre. For examples, an antenna with a power rating of 5 W/cm² can transmit a signal at a distance of 4 inches. A 10 W/cm² antenna can transmit a signal at a distance of 8 inches. If you don’t select the right power rating, your RFID solution won’t work as expected. The power rating also determines your antenna’s range. A longer-range antenna can transmit a signal at a faster speed.

Choose From a Network of RFID Antennas

Once you understand your company’s requirements, it makes sense to choose from a network of RFID antennas. There are thousands of different types of antennas each from a different RFID antenna manufacturer. However, most RFID equipment suppliers have a network of antennas that work for different applications. You can also choose from a network of custom antennas. If you don’t have time to build your own antenna, opting for a network antenna can save time and money.
