This comprehensive multi-band coverage ensures global compatibility with cellular networks in North America, Europe, Asia, and other regions. The antenna achieves consistent 2.5 dBi average gain across all bands with VSWR ¡Ü1.5, providing reliable cellular connectivity for IoT devices, M2M applications, and mobile broadband equipment operating on diverse LTE networks worldwide.

IPEX-I Connector for Seamless 4G Module Integration

The antenna features a standard IPEX-I (U.FL) connector with a low-loss coaxial cable (typically 100mm length), providing plug-and-play compatibility with most 4G/LTE modules including Quectel (EC25, EC20, EG25-G), SIMCom (SIM7600, SIM7500), Telit, u-blox (SARA-R4, TOBY-L2), and other cellular IoT modules. The IPEX-I connector offers reliable electrical performance with insertion loss below 0.3 dB and is rated for 30+ mating cycles. The 50¦¸ coaxial cable maintains impedance matching and signal integrity across all LTE bands, minimizing insertion loss and ensuring optimal antenna performance for high-speed cellular data transmission.

Verified using professional RF test equipment across all major 4G/LTE frequency bands (698-960 MHz, 1710-2690 MHz): VSWR measured consistently ¡Ü 1.5 across all supported LTE bands (B1/B2/B3/B4/B5/B7/B8/B12/B13/B17/B20/B25/B26/B28/B66), ensuring excellent impedance matching for cellular IoT applications.

?Average gain of 2.5 dBi achieved across the multi-band spectrum with peak gain up to 3.5 dBi in mid-band frequencies. Return loss (S11) better than -14 dB throughout all operational bandwidths, confirming optimal power transfer to 50¦¸ cellular modules. Antenna efficiency exceeds 65% when properly mounted with recommended ground plane clearance, providing reliable 4G/LTE connectivity for global cellular networks.

Q: Which 4G/LTE bands does this antenna support?

A: The TX4G-FPC-4015 supports all major global 4G/LTE frequency bands including B1 (2100MHz), B2 (1900MHz), B3 (1800MHz), B4 (AWS 1700/2100MHz), B5 (850MHz), B7 (2600MHz), B8 (900MHz), B12 (700MHz), B13 (700MHz), B17 (700MHz), B20 (800MHz), B25 (1900MHz), B26 (850MHz), B28 (700MHz), and B66 (AWS-3). This comprehensive coverage spans low-band (698-960 MHz), mid-band (1710-2170 MHz), and high-band (2300-2690 MHz) spectrum, ensuring compatibility with cellular networks in North America (AT&T, Verizon, T-Mobile), Europe (Vodafone, Orange, O2), Asia (China Mobile, NTT DoCoMo), and other global regions. The antenna maintains VSWR ¡Ü1.5 and 2.5 dBi average gain across all supported bands.

Q: How do I install this FPC antenna for optimal 4G/LTE performance?

A: For optimal 4G/LTE performance, mount the antenna on or near a ground plane (minimum 60mm ¡Á 60mm recommended, larger is better for low-band performance). Position the antenna at the edge or corner of your device enclosure, away from metal components, batteries, LCD displays, and other RF sources (minimum 10mm clearance). Clean the mounting surface with isopropyl alcohol, peel the protective film from the 3M adhesive backing, and firmly press the antenna onto the surface. Connect the IPEX-I connector to your 4G module's main antenna port. For devices with MIMO capability, use a second antenna on the opposite side of the enclosure with at least 50mm separation. The antenna performs best when mounted inside plastic enclosures (ABS, PC, or similar low-permittivity materials); avoid metal enclosures or position the antenna near a plastic window. Verify performance using your 4G module's signal strength indicators (RSSI, RSRP, RSRQ) after installation.

Q: What is the expected signal strength and data throughput with this antenna?

A: Signal strength and data throughput depend on cellular network coverage, distance to cell tower, environmental conditions, and antenna installation quality. With proper installation (adequate ground plane, optimal placement, plastic enclosure), expect RSSI values of -60 to -90 dBm in areas with good cellular coverage, supporting LTE data rates from 10-150 Mbps depending on your module's category (Cat-1: 10 Mbps, Cat-4: 150 Mbps, Cat-M1: 1 Mbps). The 2.5 dBi gain provides approximately 1.8x range improvement compared to a 0 dBi reference antenna. Internal antenna placement typically reduces signal strength by 3-6 dB compared to external antennas, but the compact integration is often worth this trade-off for portable devices. For maximum performance in weak signal areas, consider using MIMO configuration (two antennas) or upgrading to an external antenna with higher gain (5-7 dBi).

Q: Can I use this antenna for 5G or other wireless technologies?

A: The TX4G-FPC-4015 is optimized specifically for 4G/LTE frequency bands (698-2690 MHz) and is NOT suitable for 5G NR (New Radio) frequencies, which operate at higher bands including 3.3-3.8 GHz (n77/n78) and mmWave (24-40 GHz). However, the antenna's coverage does overlap with some legacy 3G/UMTS bands (850/900/1800/1900/2100 MHz) and 2G/GSM bands, providing backward compatibility for modules that support multi-mode operation (2G/3G/4G). The antenna is NOT compatible with WiFi (2.4/5 GHz), Bluetooth (2.4 GHz), or GPS (1575 MHz) - these technologies require separate dedicated antennas. For 5G applications, please refer to our TX5G series antennas designed for sub-6 GHz 5G NR bands.
