As IoT devices rapidly evolve toward miniaturization, portability, and high performance, the "space crunch" inside devices poses unprecedented challenges for antenna design. To address this core need, Chengdu Ebyte (EBYTE) has launched a new internal antenna product matrix covering a wide range of frequency bands and featuring both PCB and FPC materials. This series aims to provide a complete, high-performance antenna solution for compact IoT devices, supporting everything from mainstream communication to proprietary IoT protocols.

Product Overview: Dual-Material, Full-Band Coverage

The newly released models, leveraging both PCB (rigid board) and FPC (flexible printed circuit) technologies, precisely cover key frequency bands required by devices:

  • Wi-Fi/Bluetooth/Zigbee Bands (2.4GHz & Dual-Band):
    PCB: TX2400-PCB-4808 (48mm x 8mm), TX915-PCB-9514 (95mm x 14mm, for long-distance applications).
    FPC: TX2400-FPC-4405 (44mm x 5mm), TX2400-FPC-1908 (19mm x 8mm, ultra-miniature), TXWF-PCB-4814 (2.4/5.8GHz dual-band).

  • 4G/LTE Full-Network Bands:
    FPC: TX4G-FPC-4707 (47mm x 7mm), supporting 698-960MHz/1710-2700MHz for stable connections in Cat.1 and 4G modules.

  • GPS/BDS Positioning Bands:
    PCB: TXGB-PCB-3709 (37mm x 9mm), designed for precise positioning in vehicle navigation and asset tracking devices.

  • Proprietary IoT Bands (433MHz, 470MHz, 915MHz):
    PCB: TX915-PCB-7505 (75mm x 5mm, slim design).
    FPC: TX915-FPC-3009 (30mm x 9mm), TX470-FPC-5514 (55mm x 14mm), TX433-FPC-4810 (48mm x 10mm), TX433-FPC-2818 (28mm x 18mm, near-square design).

Core Advantages: Tailored Selection, High Performance

  1. PCB Antennas: Robust Structure, Stable Performance
    Made of rigid materials like FR4, PCB antennas offer high structural strength and consistency, ideal for fixed installations in devices requiring long-term reliability (e.g., routers, industrial gateways).

  2. FPC Antennas: Ultra-Thin, Flexible, Free Layout
    With ultra-thin, bendable, and adhesive properties, FPC antennas are perfect for space-constrained devices. Engineers can attach them to inner casings or irregular surfaces, maximizing design flexibility. The TX2400-FPC-1908 (19mm x 8mm) enables smart wearables, while the near-square TX433-FPC-2818 optimizes corner space.

  3. Band-Specific Optimization for Maximum Efficiency
    Each model is deeply optimized for specific frequency bands (e.g., TX915-FPC-3009 for 915MHz LoRa), ensuring lower VSWR and higher radiation efficiency in target bands—delivering longer communication distances and stable links.

  4. Diverse Sizes for Space Challenges
    From the ultra-small TX2400-FPC-1908 to the long TX915-PCB-9514, the series offers varied sizes, helping engineers balance performance and space for different device layouts.

Typical Application Scenarios

  • Ultra-Small Devices (Wearables, Small Trackers): Ultra-thin FPC antennas like TX2400-FPC-1908 and TX433-FPC-2818.

  • General IoT Gateways/Modules (4G Cat.1, LoRaWAN Gateways): Stable PCB or standard FPC antennas like TX4G-FPC-4707 and TX470-FPC-5514.

  • Vehicle & Industrial Devices (Car Trackers, Industrial Controllers): Reliable PCB antennas like TXGB-PCB-3709 and TX2400-PCB-4808.

Ebyte’s new PCB/FPC internal antenna matrix demonstrates its strong R&D capabilities and precise market insight. Whether for any device form factor or frequency band, engineers can find high-performance, reliable internal antenna solutions in this series. This will help hardware teams overcome RF design bottlenecks in miniaturized devices, accelerate product innovation, and deliver IoT products with stable connectivity and exceptional user experiences.
