Our 2.4GHz PCB Internal Antenna, paired with a precision MI1.13 coaxial cable and IPEX/U.FL connector, is engineered to be the hidden powerhouse of your next wireless product. This solution delivers exceptional performance in the crowded 2.4 GHz ISM band—the universal foundation for Wi-Fi, Bluetooth, Zigbee, and numerous proprietary wireless protocols. Designed for seamless integration, minimal footprint, and maximum reliability, this internal antenna assembly is the clear choice for developers and manufacturers seeking to optimize their device's wireless capability without compromising on design aesthetics or physical size.
Key Features and Engineering Excellence
Our internal antenna assembly is a testament to sophisticated miniaturization and RF engineering. It is optimized to ensure maximum efficiency and minimal signal loss, critical factors for long-range and power-efficient applications.
Precision PCB Antenna Element
The core of this solution is the Printed Circuit Board (PCB) antenna element. Utilizing advanced design techniques, the antenna is etched directly onto a small, rigid, or flexible substrate, allowing for a highly repeatable, cost-effective, and robust radiating structure. The 2.4 GHz center frequency ensures perfect tuning for global wireless standards, including Wi-Fi (802.11b/g/n), Bluetooth, and Zigbee. Unlike bulky external antennae, the PCB design is flat, lightweight, and can be easily mounted internally using adhesive or embedded within a device's casing, preserving a sleek, user-friendly external form factor. Its optimized ground plane dependency allows for consistent performance when integrated correctly into a host PCB.
Ultra-Low-Loss MI1.13 Coaxial Cable
Connectivity is guaranteed through a high-quality, ultra-thin MI1.13 coaxial cable. This choice of cable is crucial for maintaining signal integrity in compact designs. The MI1.13 cable offers superior shielding and exceptionally low attenuation—especially vital over shorter runs—ensuring the maximum possible amount of RF power reaches the antenna element, thus maximizing effective radiated power (ERP) and receive sensitivity. The slim diameter of the MI1.13 cable makes routing and integration inside constrained enclosures straightforward, offering excellent flexibility without compromising electrical performance.
Standardized IPEX/U.FL Connector
The assembly is terminated with a widely accepted IPEX/U.FL connector. This industry-standard micro-coaxial connector ensures a reliable, quick-connect interface with your main wireless module or host PCB. The snap-on mating mechanism offers excellent mechanical stability and a consistent 50-ohm impedance match, facilitating fast and high-volume manufacturing assembly processes. This standardization also provides design flexibility, allowing for easy connection to a variety of commercially available wireless modules that feature the corresponding surface-mount receptacle.
Diverse Application Scenarios
The combination of compact size, robust construction, and high-efficiency performance makes this antenna assembly indispensable across a wide spectrum of wireless applications.
Smart Home and Consumer Electronics
For smart home devices, discretion and reliable connectivity are non-negotiable. This internal PCB antenna is perfect for integration into smart thermostats, lighting controls, security cameras, smart speakers, and networked appliances. It allows manufacturers to create aesthetically pleasing products that do not feature unsightly external antennae, ensuring strong, whole-home Wi-Fi and Bluetooth communication for seamless user experience.
Industrial IoT (IIoT) and Automation
In industrial environments, devices must be rugged and compact. The high repeatability and shock resistance of the PCB antenna, combined with the secure connection of the MI1.13 cable, make it ideal for asset tracking tags, wireless sensors for condition monitoring, industrial control interfaces, and mesh networking nodes. Its internal placement protects it from harsh elements, dust, and vibration, ensuring continuous operation in challenging factory or field settings.
Wearable Technology and Medical Devices
The small dimensions and light weight are paramount for wearable tech. This antenna enables robust 2.4 GHz communication for fitness trackers, smartwatches, hearing aids, and remote patient monitoring (RPM) devices. The assembly is lightweight enough to be incorporated into body-worn electronics where power efficiency (for battery life) and small size are the most critical design constraints.
Networking Peripherals and Embedded Systems
It serves as the go-to embedded antenna for miniature routers, network interface cards (NICs), development boards, and single-board computers (SBCs) like the Raspberry Pi accessories. Developers can rely on its consistent RF performance to add high-speed 2.4 GHz Wi-Fi or low-power Bluetooth/Zigbee functionality to their custom embedded projects with a minimal addition to the device’s physical profile.
Optimization for Integration and Manufacturing
We understand that ease of integration is as important as electrical performance. The antenna’s design includes considerations for a defined keep-out area on the host PCB, providing essential guidelines for optimal RF layout and tuning. The flexible nature of the MI1.13 cable allows it to conform to the contours of your product's enclosure, simplifying mechanical design and assembly. This pre-assembled component reduces manufacturing complexity and the potential for assembly errors compared to handling separate cable and antenna elements. Choosing our 2.4GHz PCB Internal Antenna with MI1.13 cable means choosing a solution that is ready for high-volume production, engineered for peak performance, and perfectly aligned with the demanding requirements of modern compact wireless devices.
