Abracon AANI-CH-0078 Dual-Band Wi-Fi® Loop Chip Antenna

Introduction

The Abracon AANI-CH-0078 is a miniature surface-mount antenna designed for compact wireless products operating on common Wi-Fi® frequencies. Its dual-band operation, small ceramic construction, and omnidirectional radiation pattern make it well suited to space-constrained PCB designs.

Part Description

The AANI-CH-0078 is a ceramic loop chip antenna supporting both the 2.4 GHz and 5 GHz Wi-Fi bands. It measures only 1.6 mm × 0.8 mm × 0.4 mm, allowing designers to add wireless connectivity without consuming significant board area.

Designed for PCB edge mounting, the antenna provides a peak gain of up to 2.7 dBi and an average total efficiency of approximately 75%. Its omnidirectional radiation characteristic helps provide broad coverage for devices that may be used in varying orientations. As an SMD component, it is compatible with automated PCB assembly processes.
