ANT-418-SP DATA SHEET Product Dimensions Description The Splatch uses a grounded-line technique to achieve outstanding performance from a tiny surfacemount element. This unique antenna is designed for hand- or reflowmounting 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. 418-SP1 1.10” (27.94) 418-SP1 0.54” (13.7) 0.20” (5.1) 0.06” (1.5) Features • • • • • • • Recommended Footprint Electrical Specifications • • • • • • 0.20” (5.1) 0.10” (2.5) 0.08” (2.0) Very low cost Ultra-compact package Direct PCB attachment Ideal for concealed / internal mounting Perfect for compact portable devices Suitable for hand- or reflow-assembly Resistant to proximity effects Center Freq.
