HA.21.A

Antennas RF Overview

The HA.21.A is a surface-mount helical monopole antenna designed for the UHF band, specifically targeting the 868MHz ISM frequency. It offers a gain of 1.8dBi and features solder termination for PCB integration. The component has a maximum height of 11.00mm and operates within a 30MHz bandwidth centered at 868MHz.

Antennas RF Feature Summary

Compact helical coil design suitable for space-constrained applications
Omni-directional radiation pattern for consistent signal coverage
Surface mount construction with solder termination

Antennas RF Applications

ISM band wireless sensor networks
Low power wide area network (LPWAN) devices
Industrial telemetry systems

Antennas RF Procurement Notes

Verify the specific suffix designation to ensure compatibility with target frequency bands such as 433MHz, 868MHz, or 915MHz, as variations exist within the series. Confirm RoHS compliance status and check for any recent engineering change notices regarding package dimensions or material composition before finalizing procurement orders.

Antennas RF Selection Notes

Select this component when a low-profile, cost-effective solution is required for ISM band operations. Ensure the host PCB layout supports surface mount assembly and provides adequate ground plane clearance to maintain the specified 1.8dBi gain and impedance matching characteristics.

Antennas RF Part Context

This model belongs to the HA.21 family of antennas manufactured by Taoglas Limited. It represents a specialized quarter-wave helical variant optimized for stability in compact form factors, distinct from larger external connectors or ceramic patch alternatives.
