Passive anti Metal Tag 90*11MM

In modern asset-intensive industries—banking, data centers, IT infrastructure, and manufacturing—precision tracking and real-time visibility are no longer optional. Yet one challenge has consistently limited RFID adoption: metal interference.

Standard RFID tags often fail when applied to metal surfaces, causing weak signals, inconsistent reads, and unreliable tracking. That’s where the Passive Anti-Metal Tag 90×11mm becomes a game-changer.

Engineered with a PCB structure and optimized antenna design, this tag delivers stable performance, long lifespan, and high reliability, even in harsh environments and on metallic assets.

In this comprehensive guide, we’ll explore:

• What the passive anti-metal tag is
• How it’s manufactured
• Its working principle
• Core applications
• Pain points it solves
• Competitive analysis
• Bulk procurement strategies

What Is a Passive Anti-Metal Tag 90×11mm?

The Passive Anti-Metal Tag 90×11×3mm is a UHF RFID tag designed specifically for metal surfaces. It uses a PCB (Printed Circuit Board) substrate to isolate the antenna from the metal, ensuring stable signal transmission.

Key Characteristics:

• Passive RFID (no battery required)
• Optimized for metal environments
• Compact and slim design
• Long service life (up to 10 years)
• Strong durability in harsh conditions

Typical Applications

This tag is widely used in:

• Bank asset management (precious metals, vault assets)
• Data center equipment tracking
• IT asset management
• Industrial tools and machinery tracking

Technical Specifications

How Is the Passive Anti-Metal Tag Manufactured?

The performance of this tag depends on precision engineering and high-quality materials.

1. PCB Substrate Fabrication

The tag is built on a high-performance PCB board, which:

• Provides mechanical strength
• Reduces signal interference
• Enhances durability

2. Antenna Design and Etching

A UHF antenna is carefully designed and etched onto the PCB:

• Tuned for 860–960 MHz frequency
• Optimized for metal compatibility
• Ensures consistent signal transmission

3. Chip Integration

The RFID chip—such as Impinj M4QT or Alien Higgs3—is mounted onto the PCB.

This step includes:

• Precision bonding
• Electrical calibration
• Data encoding capability

4. Encapsulation and Protection

The tag is sealed to protect against:

• Moisture
• Dust
• Mechanical stress

5. Quality Testing

Each tag undergoes:

• Read/write testing
• Temperature resistance checks
• Signal performance verification

Working Principle of Passive Anti-Metal Tags

The tag operates using passive UHF RFID technology, meaning it does not require a battery.

How It Works:

1. An RFID reader emits radio waves
2. The tag antenna receives the signal
3. The chip is powered by the signal
4. The chip transmits stored data back
5. The system processes the information
