Overview

The ANT-2.4-CW-RH-SMA is a compact, reduced-height 1/4-wave whip antenna designed for 2.4GHz ISM band applications including Bluetooth, ZigBee, and Wi-Fi. Measuring only 18.6mm in length, this helical-element antenna provides a low-profile wireless solution where space is constrained. It features a standard SMA connector and operates across a frequency range of 2.39GHz to 2.49GHz.

Why Choose This Part

The primary advantage is its extremely small physical footprint, standing less than 19mm tall while maintaining a VSWR of less than 2.0 at the center frequency. The rugged weather-resistant jacket and SMA connector provide a durable, professional interface compared to internal PCB or chip antennas.

Applications

Handheld IoT Devices
Ideal for portable monitors and controllers where a long whip antenna would be prone to damage or ergonomically intrusive.
Smart Home Hubs
Used in compact gateways and localized controllers that require a professional external antenna connection in a small form factor.
Industrial Sensors
Provides reliable 2.4GHz connectivity for machine-mounted sensors where vertical clearance is limited.

Getting Started

To achieve specified performance, this 1/4-wave antenna must be mounted to a conductive ground plane that acts as the second half of the dipole. Engineers should ensure the SMA bulkhead is securely fastened to the enclosure and that the ground plane dimensions are sufficient to minimize VSWR and optimize the -0.9dBi gain.
