Multiband ceramic antenna

　　Multiband Ceramic Antenna: One Antenna, Multiple Connectivity Solutions for Smart Devices

　　In the era of interconnected electronics—where a single device needs to support Bluetooth, Wi-Fi, GPS, and IoT protocols simultaneously—traditional single-band antennas create bottlenecks: crowded PCBs, increased assembly costs, and compatibility conflicts. Our Multiband Ceramic Antenna solves this by integrating multiple communication bands into one compact ceramic module, enabling seamless multi-protocol connectivity while saving 30%+ PCB space. We leverage advanced frequency tuning technology to ensure stable performance across bands, making it the ideal choice for multi-functional smart devices.

　　Core Advantages of Our Multiband Ceramic Antenna

　　1. Broad Band Coverage for Versatile Connectivity

　　Our standard multiband models cover the most in-demand wireless bands, eliminating the need for multiple single-band antennas:

　　Dual-Band (2.4GHz + 5GHz): Supports Bluetooth 5.3/BLE and Wi-Fi 6/6E—perfect for smart home devices (e.g., smart speakers, Wi-Fi cameras) and wearables (e.g., smart watches with wireless charging).

　　Tri-Band (2.4GHz + 5GHz + 1575MHz): Adds GPS/GLONASS positioning to dual-band functions—ideal for outdoor devices (e.g., fitness trackers, portable navigation devices, asset trackers).

　　Quad-Band (2.4GHz + 5GHz + 1575MHz + 868/915MHz): Integrates NB-IoT/LoRa for long-range IoT communication—suitable for industrial sensors (e.g., remote water meters) and smart city devices (e.g., street lamp controllers).

　　Custom Band Combinations: Tailor to unique needs (e.g., 2.4GHz + 433MHz + 1575MHz for medical wearables with low-power connectivity).

　　2. High Isolation & Low Interference

　　Multi-band operation requires strict anti-interference design—our antennas excel here:

　　High Inter-Band Isolation (>25dB): Prevents signal crosstalk between bands (e.g., 2.4GHz Bluetooth won’t disrupt 5GHz Wi-Fi), ensuring stable data transmission.

　　Low Intermodulation Distortion (IMD < -60dB): Avoids harmonic interference with other device components (e.g., batteries, microchips), maintaining signal purity.

　　Optimized Filter Design: Built-in miniaturized filters reduce out-of-band radiation, complying with global wireless regulations (FCC Part 15, ETSI EN 300 328).

　　3. Compact Size & Easy Integration

　　Space-Saving Design: Standard dimensions (3mm×5mm×1mm to 6mm×8mm×1.5mm)—smaller than combining 2-3 single-band antennas, fitting into ultra-compact devices (e.g., true wireless earbuds, mini IoT modules).

　　SMT Compatibility: Supports automated surface-mount technology, matching high-volume production lines (e.g., smart phone factories) and reducing assembly time by 40%.

　　Lightweight: Weight as low as 0.1g, ideal for wearables (e.g., smart rings) and portable devices where weight is critical.

　　4. Stable Performance Across Environments

　　Wide Temperature Range: Operates reliably from -40°C to 85°C, suitable for outdoor (e.g., solar-powered IoT sensors) and automotive (e.g., in-car infotainment systems) applications.

　　Moisture & Dust Resistance: IP65-rated encapsulation (optional IP67 for harsh environments) protects against water and dust—ideal for fitness trackers and outdoor asset tags.

　　Consistent Gain: Typical gain of -3dBi to +2dBi across all bands, ensuring no weak links in multi-protocol communication (e.g., GPS positioning accuracy within 10 meters, Bluetooth range up to 100m).
