The Dual-Band 2.4/5 GHz PCB Internal Antenna is a critical component for devices requiring robust, high-performance wireless connectivity across both the standard 2.4 GHz and high-speed 5 GHz Wi-Fi bands. This makes it an ideal choice for modern products utilizing Wi-Fi 5 (802.11ac) and Wi-Fi 6 (802.11ax) standards, which rely heavily on dual-band operation.
This antenna features a rigid Printed Circuit Board (PCB) element that is precisely tuned to resonate efficiently across the wide combined spectrum of 2.4 GHz to 2.5 GHz and 4.9 GHz to 5.85 GHz. Its low-profile design is paired with an ultra-fine 1.37 Coaxial Cable for minimal footprint and reliable signal delivery. This assembly offers a powerful, space-saving solution for embedded applications like smart gateways, dual-band routers, high-resolution streaming devices, and industrial terminals.
True Dual-Band Performance for Modern Wi-Fi
The key feature of this antenna is its ability to operate effectively across two distinct and widely separated frequency ranges. This is essential for modern high-performance wireless systems.
Comprehensive Spectrum Coverage
2.4 GHz Band (2.4 - 2.5 GHz): Provides the foundational long-range and building penetration capabilities. This band is critical for maintaining connectivity to older devices and for ensuring wide-area coverage, as the lower frequencies travel farther and better navigate obstacles.
5 GHz Band (4.9 - 5.85 GHz): Provides the high-speed, high-capacity connectivity needed for high-definition streaming, large data transfers, and applications requiring low latency. By using the cleaner, wider channels available at 5 GHz, the antenna enables higher data throughput essential for Wi-Fi 5 and Wi-Fi 6 standards.
The PCB design is meticulously balanced to ensure optimal impedance matching and radiation efficiency in both bands simultaneously, preventing signal degradation when switching between frequencies.
Designed for Embedded Excellence: The PCB Advantage
The PCB antenna is renowned for its stability, repeatability, and efficiency in internal mounting applications.
Rigid, Repeatable, and Reliable
The antenna's element is etched directly onto a rigid PCB substrate, offering significant advantages for mass production and long-term reliability:
High Repeatability: Manufacturing the element on a PCB ensures extremely tight tolerances, guaranteeing consistent performance across every unit—a vital factor for high-volume production.
Mechanical Stability: The rigid nature of the PCB resists physical deformation and environmental changes (like temperature shifts) better than flexible elements, ensuring stable tuning and preventing detuning after installation.
Streamlined Integration: The rigid structure often allows for secure mounting within the device enclosure via screws or adhesive, simplifying the final assembly process.
Compact Connection: 1.37 Cable and I-PEX Interface
The electrical connection is designed for the rigorous space constraints of embedded systems.
Ultra-Fine 1.37 Coaxial Cable
The antenna is connected using a 1.37 Coaxial Cable, which is an ultra-fine gauge cable chosen specifically for its balance of low-loss electrical performance and superior physical flexibility in miniature assemblies.
Minimal Footprint: The cable's fine diameter ensures it takes up virtually no space, facilitating neat and efficient routing within complex device enclosures.
Signal Integrity: Provides essential shielding and low attenuation over typical embedded lengths, preserving the quality of the dual-band signal.
Universal Micro-Coaxial Connector
The cable is terminated with the industry-standard micro-coaxial connector (typically I-PEX or U.FL).
Seamless Integration: This connection type ensures quick, simple, and reliable snap-on connectivity to the mating receptacle found on nearly all modern dual-band wireless modules and SoCs.
Vibration Resistance: The connector mechanism provides a secure mechanical lock, maintaining the connection even in devices subject to movement or vibration.
Ideal Applications for Dual-Band Integration
The Dual-Band 2.4/5 GHz PCB Internal Antenna is the preferred choice for devices requiring versatile, high-speed wireless access:
Smart Hubs and Gateways: Providing dual-band Wi-Fi access for internal connectivity and external networking.
High-Resolution Streaming Devices: Ensuring stable, high-throughput 5 GHz links for uninterrupted 4K/8K video content.
Embedded Routers: Building compact, reliable dual-band Wi-Fi access points into various commercial or industrial equipment.
Gaming Consoles and PC Peripherals: Offering the low-latency, high-speed connection required for optimal gaming and data transfer experiences.
Choose this antenna for a professional, high-quality, and reliable dual-band solution that ensures your product can leverage the full speed and range capabilities of modern Wi-Fi networks.
