W5100

Antennas RF Overview

The Pulse Electronics W5100 is a passive multiprotocol PCB antenna designed for on-ground BLE-NFC combination applications. It supports dual-band operation with center frequencies at 13.56 MHz and 2.45 GHz, covering protocols including Bluetooth, BLE, WiFi, ANT, Thread, Zigbee, and NFC. The component features a T-Panel mechanical style with SMD/SMT termination and adhesive mounting. Key electrical parameters include -1 dBi gain, 50 Ohms impedance, and a VSWR of 3:1. It operates within a temperature range of -40°C to +85°C and measures 40 mm in length and width with a height of 1.2 mm.

Antennas RF Procurement Notes

Verify the specific datasheet version and RoHS compliance status prior to procurement, as manufacturer specifications may be updated. Confirm that the adhesive mount style aligns with the target enclosure material requirements. Ensure the SMD/SMT termination method is compatible with the assembly process. Cross-reference the 40x40 mm footprint dimensions against the final PCB layout to guarantee proper clearance and placement.

Antennas RF Selection Notes

Select this component when a single antenna solution is required to handle both 13.56 MHz NFC and 2.4 GHz wireless protocols simultaneously. The -1 dBi gain and 50 Ohm impedance are suitable for standard RF front-end designs. Consider the operating temperature range of -40°C to +85°C for environmental durability. The physical profile of 1.2 mm height allows for low-profile device integration where space is constrained.

Antennas RF Part Context

The W5100 belongs to Pulse Electronics' portfolio of PCB antennas, which utilize ceramic technology to achieve performance in small form factors. This model specifically addresses the need for combined wireless connectivity in modern portable devices. It is categorized under multiprotocol antennas, distinguishing it from single-band solutions by supporting both sub-GHz NFC and 2.4 GHz ISM band operations within a unified hardware platform.
