Abracon PCB Omni-Directional Antenna WiFi ISM Band LoRaWAN Surface Mount 34mm Length PRO-OB-471

Abracon PRO-OB-471 is a high-performance PCB Omni-Directional Antenna designed specifically for wireless applications including WiFi, ISM Band, and LoRaWAN protocols. This surface mount antenna features a compact 34 mm length and utilizes Planar Inverted-F Antenna (PIFA) technology, which requires mounting on a proper ground plane for optimized performance. It is ideal for industrial, networking, telemetry, and IoT applications where multi-band coverage and omni-directional signal propagation are critical.

Designed for integration into multilayer printed circuit boards, the PRO-OB-471 benefits from the addition of vias to ensure a continuous ground plane and avoid splits that could degrade antenna efficiency. The antenna has a mixed linear polarization and a low profile of 4.93 mm, making it suitable for space-constrained designs.

The antenna supports three frequency bands, effectively covering 860 MHz to 928 MHz and extending up to 2400 MHz for WiFi applications. It delivers a gain of 2.4 dBi and omni-directional directivity, providing consistent coverage in all directions. To maximize impedance matching and signal quality, implementing a matching network near the antenna is recommended.

Manufactured to comply with EU Directive 2011/65/EU and 2015/863 for RoHS, and certified under RoHS II and MSL Level 1 standards, ensuring environmental and reliability standards are met. The surface mount design allows it to be supplied on reels, facilitating automated pick-and-place assembly lines, improving production efficiency.

This antenna is widely used in telemetry systems, wireless communication devices, and IoT modules, especially in industrial, commercial, and agricultural telemetry and monitoring setups. Its multi-band capability and robust design make it suitable for sophisticated wireless telemetry and data transmission tasks.

Utilizes PIFA technology for optimal performance on a ground plane. Supports multiple frequency bands: 868, 915, and 868+2400 MHz. Omni-directional gain of 2.4 dBi ensures broad signal coverage. Compact profile of 4.93 mm allows easy PCB integration.

Compliant with EU Directive 2011/65/EU, RoHS and MSL Level 1 standards. Mixed linear polarization improves signal robustness. Recommended that vias be added for ground plane integrity in multilayer PCBs. Matching network recommended to optimize antenna impedance.
