SW190031G97 SWP003 4G/LTE Internal PCB Antenna (101mm Cable, U.FL)

Product Overview: The SW190031G97 (SWP003) is a high-performance internal rigid PCB antenna engineered for wideband cellular communication across global 2G, 3G, and 4G LTE networks. Designed as a reliable, space-saving embedded solution, this multi-band antenna covers critical lower cellular bands (824–960 MHz) as well as high-frequency bands (1710–2690 MHz). It comes equipped with an integrated 101mm micro-coaxial cable terminated with a standard U.FL/IPEX connector and features a premium 3M adhesive backing for quick and secure mounting inside non-conductive device enclosures.

Key Features:

• Wideband Cellular Connectivity: Full operational support for global 2G, 3G, and 4G LTE wireless deployments.

• Rigid PCB Construction: Durable FR-4 material chassis providing stable electrical properties and consistent omnidirectional radiation.

• Pre-Assembled Coaxial Cable: Integrated 101mm low-loss RF cable with a standard U.FL connector for stable plug-and-play board termination.

• Strong Adhesive Layer: Heavy-duty industrial 3M 9448A tape backing ensures easy peeling and firm interior positioning.

• Optimized High-Band Performance: Reaches a peak gain of up to 3.5 dBi and an efficiency of up to 55% in the high-frequency spectrum.

Frequently Asked Questions: Q1: Can this PCB antenna be shortened or cut down to fit a smaller housing? A1: No. The copper traces etched onto the FR-4 PCB are precisely tuned to match the 2G/3G/4G frequency bands. Cutting or altering the PCB will severely de-tune the internal matching network and disrupt transmission performance.

Q2: What is the ideal surface for mounting this internal antenna? A2: For optimal radiation efficiency, the antenna should be affixed onto a non-conductive plastic surface (such as ABS or polycarbonate inside the device housing). Avoid sticking the active antenna plane directly onto metal plates, shielding cans, or large batteries, as this will attenuate the cellular signal.
