Choosing the right RFID antenna is crucial for applications requiring precise, close-range tag detection - especially when working with challenging materials like metals and liquids. Today, we're exploring Times-7's True NearField antenna series, specifically designed for "near zone only" tag detection with high accuracy and reliability.
Understanding near-field technology in RAIN RFID
Before diving into the specifics of the antenna series, it's important to understand what makes near-field technology unique. Near-field technology provides key benefits for specific RFID applications. Unlike traditional RFID antennas, near-field antennas use magnetic fields for close-range communication, ensuring consistent reads without dead spots. This makes them perfect for applications where precise control is essential and stray reads must be prevented.
Why choose Times-7 True NearField Antennas?
Times-7 True NearField antennas operate with a pure near-field read zone. This means they are ideal for applications requiring precise item-level tracking without interference from surrounding tagged assets. With no surface dead spots and minimal far-field interference, they deliver consistent and reliable tag reads in a precisely controlled space.
They are available in three different sizes, making them flexible for different applications:
- A1115 – Compact (150 x 150 mm) - for space-constrained environments.
- A1130 – Medium (300 x 300 mm) - for balanced coverage.
- A1163 – Large (600 x 300 mm) - for extensive surface area coverage.

Why use a near-field antenna?
Near-field antennas work differently from regular RFID antennas because they use near magnetic fields instead of combined (far) electromagnetic fields; making them ideal for:
- Reading tags on metal and liquid-containing items (e.g., pharmaceutical vials, bottled beverages and jewelry)
- Preventing stray reads by limiting tag detection to a confined surface
- Applications that require high precision, such as item-level tracking in retail and healthcare settings
Conclusion
Selecting the right near-field antenna for your RFID system is essential for achieving accurate and reliable tag detection. The Times-7 True NearField series—A1115, A1130, and A1163—offers tailored solutions for applications that demand precise tag reads without interference.
- Choose the A1115 for small-scale, high-accuracy applications.
- Opt for the A1130 for medium-sized installations like POS-systems and shelving.
- Select the A1163 for large-scale deployments in warehouses and logistics.
