W3079
Overview
The W3079 from Pulse Electronics is a high-efficiency dual-band ceramic chip antenna designed for 2.4GHz and 5GHz wireless applications. It provides a compact surface-mount solution for devices requiring Bluetooth, Zigbee, and Wi-Fi connectivity across both frequency bands. Measuring only 3.2mm x 1.56mm, it is ideal for space-constrained IoT designs that must maintain high peak gain.
Why Choose This Part
The W3079 offers a high peak gain of 2.4dBi and a low VSWR of 1.9, ensuring efficient power transfer and extended range. Its ceramic chip construction provides excellent thermal stability from -40C to +85C and mechanical durability compared to PCB trace antennas.

Key Specifications
Getting Started
When integrating the W3079, follow the manufacturer recommended ground plane dimensions and keep-out areas to ensure proper impedance matching. Engineers should use a 50-ohm microstrip feed line and may require a pi-matching network to tune the antenna to the specific enclosure and PCB stack-up.
