Description
ISMP.868 is a low-profile embedded ceramic patch antenna designed for the 868MHz ISM band. Its compact form factor helps deliver reliable performance while using minimal board space.
When mounted on a 70x70mm ground plane, it provides strong efficiency and peak gain, with right-hand circular polarization (RHCP) and low axial ratio to help maintain link reliability where device orientation can change.
- Designed for 868MHz ISM: suitable for LPWAN networks and 868MHz ISM deployments
- Compact embedded patch form factor: supports space-constrained devices
- RHCP radiation: helps improve link robustness in changing orientations
- Supports custom tuning: available for specific device environments (subject to NRE and MOQ)
