Unleash the full potential of your next-generation wireless products with our high-efficiency 2.4GHz & 5GHz 3dBi PCB Patch Antenna. This powerful dual-band solution is meticulously engineered to provide stable, reliable connectivity across both the legacy 2.4 GHz band and the high-speed 5 GHz band, the foundation of modern Wi-Fi 4 (802.11n), Wi-Fi 5 (802.11ac), and Wi-Fi 6 (802.11ax) standards. Featuring a consistent 3dBi gain across both bands, a robust Printed Circuit Board (PCB) patch design, a low-loss 1.37 coaxial cable, and terminating in a premium MHF1 connector, this antenna assembly is the definitive choice for compact, high-throughput wireless embedded systems.
Advanced Dual-Band RF Engineering
This antenna represents a significant advancement in embedded connectivity, offering broad spectrum coverage and high performance in a small footprint.
True Dual-Band Coverage
The antenna is expertly designed to operate seamlessly across the two most critical license-free wireless bands:
2.4 GHz (2400-2500 MHz): Provides backward compatibility and long-range communication for legacy Wi-Fi devices, Bluetooth, and Zigbee, offering excellent penetration through walls and floors.
5 GHz (5150-5850 MHz): Enables high-speed, high-throughput data transmission, crucial for streaming video, large file transfers, and low-latency applications that benefit from the less congested channels available on the 5 GHz band.
This dual-band capability ensures that your device can connect to the fastest available network, dynamically switching to maintain the best possible connection quality.
Consistent 3dBi Gain with PCB Patch Structure
The radiating element utilizes a PCB Patch Antenna design, known for its repeatable performance and mechanical stability. It provides a reliable 3dBi peak gain across the entire operational spectrum of both the 2.4 GHz and 5 GHz bands. This consistent, moderate gain is optimized for embedded devices where omnidirectional coverage and a balanced link budget are required. The patch structure’s inherent directivity, when properly mounted, helps focus signal energy, improving efficiency without requiring complex orientation adjustments.
Optimized 1.37 Coaxial Cable for Minimal Loss
To bridge the distance between the antenna element and the wireless module, we use an ultra-slim 1.37 coaxial cable. This specific cable choice offers an excellent compromise between flexibility for routing in tight enclosures and minimizing signal attenuation at these high frequencies. The low-loss characteristics of the 1.37 mm cable are essential to ensure the 3dBi gain is effectively delivered to the radio front-end, preserving the integrity of the high-frequency 5 GHz signals.
Premium MHF1 Connector for Reliability
The antenna assembly terminates with a MHF1 connector. As a superior micro-coaxial interface, the MHF1 connector ensures a secure, positive lock and maintains a perfect 50-ohm impedance match with the host PCB. Its robust design is highly reliable against vibration and repeated handling, making it the ideal choice for high-volume manufacturing and long-term deployment in commercial and industrial products.
Key Application Scenarios
The versatility and high throughput offered by dual-band support make this antenna critical for a wide array of demanding wireless products.
Next-Generation Smart Home Devices
For modern smart devices like 4K video streaming hubs, mesh Wi-Fi repeaters, and smart security cameras, the need for high-throughput 5 GHz connectivity is essential. This antenna enables these devices to handle bandwidth-intensive tasks while maintaining 2.4 GHz compatibility for older accessories, ensuring seamless integration into any home network.
High-Performance Embedded Systems
This antenna is perfectly suited for use in miniature industrial PCs, single-board computers (SBCs), and compact networking appliances where space is at a premium but data demands are high. It provides the robust wireless backbone necessary for cloud connectivity, remote diagnostics, and real-time data processing in embedded applications.
Portable and Mobile Computing
For devices such as ruggedized tablets, portable diagnostic equipment, and mobile data terminals, the ability to connect to both 2.4 GHz and 5 GHz networks ensures maximum mobility and speed. Users can enjoy faster downloads and more stable connections when near a 5 GHz router, while the 2.4 GHz band provides crucial backup coverage when further afield.
Advanced IoT Gateways and Commercial Systems
In commercial settings like retail or hospitality, IoT gateways and digital signage require dedicated high-speed channels for content delivery and system management. Utilizing this dual-band antenna allows these devices to connect to high-throughput enterprise 5 GHz Wi-Fi networks for mission-critical data while using the 2.4 GHz band for connecting low-power BLE or Zigbee sensors.
