The FME Connector Multi-Frequency Patch Antenna is a compact microstrip patch antenna engineered for IoT gateways, LoRaWAN nodes, smart metering, and industrial M2M systems requiring reliable ISM-band connectivity. Covering 433 MHz, 868 MHz, 912 MHz, 920 MHz, and 2.4 GHz, this PCB-based patch antenna offers selectable gain of 3 dBi, 5 dBi, or 6 dBi with VSWR ≤ 1.5 across all supported bands, ensuring efficient power transfer and minimal signal reflection.
Built on an FR4 substrate with an integrated ground plane, the radiating patch element is enclosed in a UV-stabilized ABS radome rated IP65 for outdoor durability. The assembly includes a pre-terminated FME connector and 2.5-meter RG174 coaxial cable, eliminating field soldering and guaranteeing consistent 50 Ω impedance from the patch feed point to the radio port. Adhesive, magnetic, or screw mounting options enable versatile installation on metal enclosures, plastic housings, or vehicle roofs.
Manufactured under ISO 9001 with 100% VSWR screening, every unit is RoHS and REACH compliant. OEM customization—frequency tuning, gain selection, cable length, connector swap, and private labeling—is available from 500 pcs with rapid prototyping to accelerate your product launch.

Q1: What is a multi-frequency PCB patch antenna and how does it differ from a ceramic chip antenna?
A multi-frequency PCB patch antenna uses a microstrip radiating element etched on FR4 substrate with an integrated ground plane, offering higher gain (3–6 dBi) and broader bandwidth than ceramic chip antennas. This FME RG174 2.4G 433MHz 868MHz patch antenna is ideal for IoT gateways requiring stable broadside radiation, whereas ceramic antennas suit space-constrained wearable devices with lower gain requirements.
Q2: Can this 433MHz 868MHz 912MHz patch antenna be tuned to non-standard ISM frequencies for OEM projects?
Yes, our RF engineering team can retune the PCB patch dimensions and feed network to any ISM frequency between 400 MHz and 2.5 GHz. OEM orders starting at 500 pcs include HFSS simulation, prototype fabrication, and anechoic chamber validation to ensure VSWR ≤ 1.5 at your target frequency. Rapid sampling delivers tuned samples within 5–7 working days for accelerated certification.
Q3: What cable loss should I expect from 2.5 meters of RG174 at 920 MHz and 2.4 GHz?
RG174 exhibits approximately 1.1 dB/m at 920 MHz (2.75 dB total) and 1.8 dB/m at 2.4 GHz (4.5 dB total). For longer runs or 2.4 GHz WiFi applications, we recommend upgrading to RG316 or LMR100 to reduce insertion loss. Our engineers can calculate optimal cable type based on your link budget and provide custom-length assemblies pre-terminated with FME or SMA connectors.
Q4: Is this IP65-rated FME patch antenna suitable for outdoor smart metering and LoRa gateway installations?
Absolutely. The UV-stabilized ABS radome is sealed to IP65, protecting the FR4 patch element against rain, dust, and temperature extremes from −40 °C to +85 °C. The integrated ground plane ensures stable radiation patterns regardless of mounting surface. This antenna has been deployed in large-scale AMI and LoRaWAN networks across Europe and Asia with proven long-term field reliability.
Q5: How does the 3 dBi vs 5 dBi vs 6 dBi gain option affect coverage for 868 MHz LoRa applications?
Higher gain narrows the vertical beamwidth: 3 dBi provides ~120° coverage for dense urban node clusters, 5 dBi offers ~90° for suburban deployments, and 6 dBi delivers ~70° for long-range rural links. All three options maintain VSWR ≤ 1.5 at 868 MHz. We recommend selecting gain based on your node density and regulatory EIRP limits; our team can assist with link budget calculations.
Q6: Can I swap the FME connector for SMA or N-Type without redesigning the patch antenna?
Yes, connector swaps are standard OEM customization items. The PCB feed point accommodates FME, SMA, RP-SMA, N-Type, TNC, MCX, or MMCX connectors without altering the radiating element. This flexibility allows you to standardize on a single patch antenna platform across multiple product lines while matching each device’s RF port specification. MOQ for connector variants is 500 pcs.
Q7: Does this multi-frequency patch antenna comply with RoHS and REACH for European market export?
All materials are fully RoHS 2.0 and REACH SVHC compliant. We provide RoHS test reports, REACH declarations, and CE/FCC certification support documentation with every export shipment. This ensures smooth customs clearance and regulatory compliance for deployments in the EU, UK, and other markets requiring environmental conformity assessment for RF equipment.
