ANT-418-SP DATA SHEET
Description
418-SP1
The Splatch uses a grounded-line
technique to achieve outstanding
performance from a tiny surface-
mount element. This unique antenna
is designed for hand- or reflow-
mounting directly to a product’s circuit board. Its low cost makes
it ideal for volume applications. Unlike many compact antennas,
the Splatch exhibits good proximity performance, making it an
appropriate choice for handheld applications such as remote
controls, pagers, and alert devices.
