Engineered for multi-regional IoT deployments and industrial telemetry systems requiring seamless frequency agility across global ISM bands, this compact patch antenna delivers selectable 3 dBi, 5 dBi, or 6 dBi gain profiles at 433 MHz, 868 MHz, 912 MHz, and 920 MHz through a single FME-connected assembly. The integrated 2.5-meter low-loss RG174 cable provides flexible routing from enclosure to radio module while maintaining <1.2 dB insertion loss across all supported bands—eliminating field-tuning and adapter losses common in multi-band solutions. As an ISO-certified manufacturer serving Fortune Global 500 partners in 80+ countries, Zhenjiang Binjiang Electronic offers full OEM customization of gain, cable length, connector type, and mounting hardware with functional prototypes delivered within 5–7 business days. Every unit undergoes individual VSWR validation and cable loss testing to ensure compliance-ready performance out-of-box.

●True Multi-Band Single-Antenna Solution: Covers four critical ISM frequencies (433/868/912/920 MHz) without switching or retuning; enables global product SKUs with region-agnostic hardware deployment.
●Selectable Gain Profiles: Choose 3 dBi for wide-area mesh coverage, 5 dBi for balanced range/focus, or 6 dBi for point-to-point links—all from identical mechanical form factor simplifying inventory management.
●Integrated 2.5m RG174 Cable Assembly: Factory-terminated FME connector eliminates field crimp errors; pre-tested insertion loss (<1.2 dB @ 920 MHz) ensures predictable link budgets without external calibration.
●Compact Patch Form Factor: 65×65 mm footprint mounts flush on metal enclosures, DIN rails, or vehicle roofs; directional beam reduces multipath interference versus omnidirectional whips in dense urban RF environments.
●No-Tune Wideband Operation: Pre-matched internal circuitry maintains VSWR ≤1.5:1 across all four bands; zero field adjustment required during installation or regional reconfiguration.
●OEM Cable & Connector Flexibility: Customize cable length (0.5–5 m), type (RG174/RG316/LMR195), and connector (FME/SMA/N/TNC) to match exact radio chassis layout—no minimum order for prototyping.
●Compliance-Ready Validation: Includes serialized test report covering all four frequencies; accelerates CE/FCC certification for end products by eliminating redundant antenna re-testing.

How does one antenna cover four different frequencies without tuning?
Our patch uses a multi-resonant slot geometry and broadband matching network that creates four distinct impedance minima at 433/868/912/920 MHz. Unlike narrowband whips requiring physical length adjustment, this printed radiator maintains VSWR ≤1.5:1 across all bands simultaneously through electromagnetic coupling—not electronic switching. No user intervention needed; install once and deploy globally.
Why choose FME over SMA connectors for this application?
FME’s smaller diameter (8 mm vs. SMA’s 11 mm) allows tighter cable bend radii (15 mm min.) crucial for routing inside compact IoT enclosures. Thread engagement is more vibration-resistant than SMA in mobile/industrial mounts. Electrically equivalent up to 1 GHz; insertion loss difference<0.05 dB. For legacy equipment requiring SMA, specify adapter-free SMA variant during quoting—we stock both.
Can I mix gain levels across different frequencies in one unit?
Standard SKUs offer uniform gain across all four bands. For asymmetric requirements (e.g., 6 dBi @ 915 MHz + 3 dBi @ 433 MHz), request custom tuning during quotation. This requires modified patch geometry and matching network; adds 3–5 days to prototype lead time but enables optimized link budgets per region. No extra tooling charge for gain asymmetry.
What’s the real-world range difference between 3/5/6 dBi options?
At 868 MHz with 14 dBm TX power: 3 dBi achieves ~2 km LOS, 5 dBi extends to ~3.5 km, 6 dBi reaches ~4.5 km. Higher gain narrows horizontal beamwidth (3 dBi=90°, 6 dBi=70°), improving SNR in directional links but reducing angular coverage. For mobile nodes with unpredictable orientation, 3–5 dBi recommended; fixed infrastructure benefits from 6 dBi focus. Link budget calculator provided upon request.
Is the 2.5m RG174 cable suitable for outdoor installations?
RG174 jacket is UV-stabilized and rated for -40°C to +85°C continuous operation, surviving rain, dust, and temperature extremes. However, for permanent rooftop/mast mounts exceeding 3 years exposure, specify LMR195 upgrade (+$0.80/unit) for superior UV resistance and lower loss (<0.8 dB @ 920 MHz over 2.5m). Both cables pass IP65 ingress testing when mated; strain relief boots included standard.
What testing validates multi-band performance before shipment?
Every unit undergoes: (1) Individual VSWR sweep across all four frequencies (433/868/912/920 MHz), (2) Cable insertion loss verification (<1.2 dB @ 920 MHz), (3) Mechanical pull-test on FME connector (≥30 N retention force). Sample units per batch receive full 3D radiation pattern measurement plus environmental stress screening (-40°C/+85°C thermal cycling, 95% RH soak). Serialized test reports retained 10 years; Certificate of Conformance included. Manufacturing follows ISO 9001 with IPC-A-610 Class 2 workmanship.
