In the fast-paced world of automotive technology, innovation is key to enhancing convenience and security. At VLG we are proud to introduce our state-of-the-art NFC antenna designed specifically for keyless entry systems in vehicles. This advanced technology represents the future of automotive access, providing users with seamless entry and superior performance.
Transforming Vehicle Access with NFC Technology
Near Field Communication (NFC) has revolutionized how we interact with our environments. When integrated into vehicle keyless entry systems, NFC allows users to unlock their cars effortlessly by simply approaching with their NFC-enabled device or key fob. Our NFC antenna is at the forefront of this technology, combining high performance with ease of use.
1. Superior Performance and Precision
Double-Sided Microstrip Design
Our NFC antenna utilizes a double-sided microstrip design, which significantly enhances its performance compared to traditional single-sided configurations.
This design incorporates microstrip patch antennas on both sides of a dielectric substrate, which offers several technological advantages:
Enhanced Bandwidth and Gain: The double-sided microstrip design increases the effective aperture of the antenna, leading to improved bandwidth and gain. By utilizing both sides of the substrate, the antenna can support a wider frequency range and higher gain, which is crucial for accurate NFC communication at 13.56 MHz
ENTRY SYSTEMImproved Radiation Efficiency: This configuration optimizes the radiation pattern by leveraging the symmetrical distribution of the microstrip patches. The dual-sided layout reduces energy loss and improves radiation efficiency, resulting in a more consistent and reliable signal.
Reduced Surface Wave Losses: The dual patch arrangement minimizes surface wave losses, which are typically present in single-sided designs. By reducing these losses, the antenna achieves better performance with higher precision in signal induction and reduced signal degradation.
High-Performance Filters
The antenna incorporates high-performance filters that are integral to its advanced signal processing capabilities.
These filters are designed to address several critical aspects of NFC communication:
Signal Interference Mitigation: The filters used in our NFC antenna are engineered to suppress out-of-band interference and noise. By employing narrowband filters with precise cut-off frequencies, the antenna minimizes the impact of external electromagnetic interference, which ensures that only the desired NFC signal is processed.
Enhanced Selectivity and Sensitivity: The filters enhance the selectivity of the antenna system by allowing only the frequencies within the NFC band to pass through while attenuating unwanted signals. This high selectivity improves the sensitivity of the antenna to NFC tags, resulting in more reliable and accurate signal detection.
Low Insertion Loss: Our filters are designed with minimal insertion loss, which maintains the signal strength and integrity as it passes through the antenna system. This characteristic is crucial for ensuring that the NFC communication remains robust and effective, even in environments with potential signal attenuation.
Improved Signal-to-Noise Ratio (SNR): By reducing noise and interference, the filters enhance the signal-tonoise ratio of the antenna system. A higher SNR ensures clearer communication between the NFC device and the car’s unlocking system, leading to quicker and more secure unlocking operations.
2. Compact and Versatile Installation
Space-Efficient Design
Our NFC antenna is engineered with a compact form factor, optimizing spatial efficiency and installation versatility. The design incorporates the following advanced features:

Installation Time: The streamlined installation process typically requires [specific time, e.g., 30 minutes] with minimal tools, facilitating quick integration into both new and aftermarket vehicles.
3. Enhanced Signal Transmission
Coaxial Cable Integration
The antenna features integrated coaxial cables for differential signal transmission, enhancing performance in
electromagnetically complex environments:
Signal Type: The antenna uses [specific cable type, e.g., RG-174 coaxial cables] to transmit differential signals. This approach minimizes signal degradation and maximizes fidelity by maintaining signal integrity.
Impedance Matching: The coaxial cables are designed with a characteristic impedance of [specific impedance, e.g., 50 Ω ± 3 Ω], ensuring optimal impedance matching with the antenna system and minimizing signal reflections.
Anti-Interference Capabilities: The use of coaxial cables enhances the antenna’s resistance to electromagnetic interference (EMI), maintaining reliable performance even in high-EMI environments. The differential signal approach significantly reduces the susceptibility to common-mode noise.
Magnetic Material and Filter
Advanced magnetic material and filtering technology are integral to the antenna’s performance:
Material Composition: The antenna incorporates double-sided magnetic materials with a permeability of [specific value, e.g., μr = 1000], which enhances the magnetic field coupling and minimizes signal losses.
Filter Specifications: Built-in filters are designed with a passband frequency of [specific range, e.g., 13.56 MHz ± 1 MHz] and attenuation characteristics of [specific values, e.g., ≥ 30 dB at frequencies outside the passband]. These filters achieve low insertion loss, typically < 1 dB, ensuring high signal quality.
Delay and Crosstalk Performance: The antenna’s design achieves a delay difference of < 2 ns and near-end crosstalk immunity of > 40 dB, resulting in minimal signal distortion and reliable communication.
4. Robust Environmental Performance
Wide Operating Temperature Range
