Overview

The WLA.01 is a compact 3.2 x 1.6 x 0.5mm ceramic chip antenna designed for 2.4GHz applications including Bluetooth, Wi-Fi, and ZigBee. It is a high-efficiency loop antenna that offers an omni-directional radiation pattern in a low-profile surface mount package.

Why Choose This Part

With a maximum height of only 0.50mm, it is one of the thinnest 2.4GHz chip antennas available for surface mount assembly. It maintains a high efficiency of 67.8% and a peak gain of 1dBi, ensuring consistent performance despite its small physical footprint.

Applications

Bluetooth Peripherals
Ideal for space-constrained devices like wireless headphones and wearable fitness trackers.
IoT Sensor Nodes
Suitable for ZigBee and 802.11 b/g/n sensors requiring reliable short-range communication.
Mobile Accessories
Commonly used in USB dongles and PCMCIA cards due to its ultra-thin 0.5mm profile.
Handheld Electronics
Provides a compact internal antenna solution for smartphones and portable data terminals.
