Maximize the cellular performance of your compact devices with our high-efficiency 4G 2dBi PCB Built-in Patch Antenna. This solution is expertly designed to provide stable, reliable reception across the critical 4G LTE bands, ensuring fast data speeds and consistent connectivity for your embedded applications. Utilizing a sturdy Printed Circuit Board (PCB) patch design, a low-loss MI1.13 coaxial cable, and a standardized MHF (or compatible U.FL/IPEX) connector, this antenna assembly offers an integrated, space-saving solution for the demanding requirements of modern wireless hardware. It’s the perfect choice for manufacturers focused on seamless internal integration and robust cellular performance.
Engineered for Seamless 4G Cellular Integration
This internal antenna is a testament to sophisticated RF engineering, balancing the need for small form factor with the requirement for high-speed, wide-band cellular communication.
Wideband 4G LTE Frequency Coverage
The antenna is meticulously tuned to operate effectively across a broad range of 4G LTE frequencies (typically encompassing the 700 MHz to 2700 MHz spectrum). This wideband capability is essential for global deployment, ensuring compatibility with major cellular carriers and various LTE bands (including B3, B7, B20, etc., depending on the specific model optimization). Reliable 4G connectivity guarantees high-speed data transmission necessary for streaming, remote diagnostics, and large data transfers, making it a critical component for mobile and fixed cellular applications.
High-Stability PCB Patch Design
The core of the antenna is a Printed Circuit Board (PCB) patch element. This design offers superior performance repeatability compared to simpler antennae, ensuring every manufactured unit performs consistently—a vital factor for high-volume production. The patch antenna is inherently directional and polarization-optimized when correctly mounted, allowing for effective signal gain up to 2dBi. This compact, rigid PCB structure provides excellent mechanical stability, making it highly resistant to vibration and environmental stress when embedded inside a product enclosure.
Ultra-Low-Loss MI1.13 Coaxial Cable
To maintain maximum signal strength between the antenna and the cellular module, the assembly utilizes a premium, ultra-thin MI1.13 coaxial cable. This cable is chosen specifically for its extremely low signal attenuation characteristics over short runs. Minimizing loss here is paramount, as the effective radiated power (ERP) directly impacts the device's ability to maintain a connection in weak signal areas. The thin diameter of the MI1.13 cable also allows for tight bending and easy routing within crowded device enclosures.
Standardized MHF (U.FL/IPEX) Connector
The connection is secured with a universally accepted MHF connector (often referred to interchangeably as U.FL or IPEX). This industry-standard micro-coaxial connector provides a highly reliable, snap-on interface that ensures a solid 50-ohm impedance match. The MHF connector is the preferred interface for almost all commercial 4G/LTE/GSM modules, facilitating fast, simple, and error-free assembly onto the main PCB during manufacturing.
Diverse Applications Requiring Robust Cellular Data
The combination of wide-band 4G coverage, small size, and robust construction makes this antenna assembly indispensable for a variety of embedded cellular data applications.
Fleet Management and Asset Tracking
For fleet telematics, GPS vehicle tracking, and high-value asset monitoring, continuous 4G data transfer is required for real-time location and diagnostics. Embedding this PCB antenna within the tracking unit ensures a discreet, tamper-resistant installation that maintains a strong cellular link, even when the device is hidden or placed in challenging locations within a vehicle or cargo container.
Industrial IoT (IIoT) Gateways and Modems
Industrial applications often require rugged, hidden components. This antenna is perfectly suited for integrating into remote monitoring units, industrial control modems, and cellular-enabled sensors deployed in factories, utility substations, or remote field locations. It facilitates the high-throughput data backhaul necessary for predictive maintenance, remote diagnostics, and operational control.
Cellular-Enabled Security and Surveillance
The reliable 4G connection is crucial for wireless security cameras, remote alarm systems, and temporary surveillance equipment. By using this internal patch antenna, manufacturers can design aesthetically pleasing devices that do not feature visible external antennae, while still ensuring the high data rates needed for continuous video streaming and instant alerts.
Retail Point-of-Sale (POS) and Kiosks
Mobile and temporary retail solutions, such as pop-up store POS terminals, digital signage, and unattended payment kiosks, require instant, reliable cellular connectivity without reliance on local Wi-Fi. The antenna's internal design simplifies deployment and protects the cellular link from tampering or damage in high-traffic commercial environments.
