10-Pack 433MHz FPC Flexible Patch Antenna for LoRa & IoT

10-Pack 433MHz Omnidirectional FPC Flexible Patch Antennas for LoRa & Wireless Modules

Upgrade your wireless projects with this set of 10 high-quality omnidirectional FPC (Flexible Printed Circuit) patch antennas. Designed for 400–433–470 MHz frequency ranges, these compact built-in antennas deliver reliable 2 dBi gain and are ideal for LoRa modules, wireless receiver modules, IoT devices, and data transmission applications. Their ultra-slim flexible design makes them perfect for embedding inside enclosures where rigid antennas won't fit.

Key Features

• Frequency Range: 400 – 433 – 470 MHz – compatible with LoRa, ISM band, and sub-GHz wireless systems
• Omnidirectional Radiation: 360° signal coverage for consistent connectivity in all directions
• Antenna Gain: 2 dBi for improved signal strength over standard onboard traces
• Impedance: 50 Ohms – standard match for most RF modules and transceivers
• Standing Wave Ratio (SWR): ≤ 2.0 for efficient power transfer and minimal signal loss
• Compact Size: 29 mm × 6 mm – ultra-thin and flexible for tight-space installations

Frequently Asked Questions

Q: What connector type do these 433 MHz FPC flexible antennas use?

A: These antennas are designed as patch/adhesive-mount flexible antennas for direct integration onto PCBs or inside enclosures. Please review the product images for connector and pad details, as the feed point is built into the flexible circuit. If you require a specific connector (e.g., IPEX/U.FL), feel free to contact us before ordering.

Q: Are these antennas compatible with popular LoRa modules like SX1276 or RFM95?

A: Yes. These antennas operate in the 400–470 MHz band and are matched to 50-ohm impedance, making them fully compatible with common LoRa transceiver modules such as the SX1276, SX1278, RFM95, and similar 433/470 MHz sub-GHz RF chips used in Arduino, Raspberry Pi, and other development platforms.

Q: Can these FPC antennas be used outdoors?

A: Yes. The antennas support an operating temperature range of -40°C to +65°C, making them suitable for both indoor and outdoor embedded applications. For fully outdoor installations, it is recommended to house the antenna inside a weatherproof enclosure to protect the flexible circuit from moisture and UV exposure.

Q: What is the benefit of an FPC antenna over a standard whip or helical antenna?

A: FPC (Flexible Printed Circuit) antennas are extremely thin and lightweight, allowing them to be mounted flat inside product housings where a rigid or protruding antenna would be impractical. They conform to curved surfaces, simplify assembly, and are ideal for compact IoT and embedded wireless designs without sacrificing reliable omnidirectional coverage.
