WS1357 13 mm x 13 mm x 5.8 mm Ultra Compact Embedded GPS Antenna

The Ultra Compact WS1357 Embedded GPS antenna is most ideal for GPS Enabled mobile phones, PDAs, laptops and portable GPS Handhelds. The WS1357 antenna series features a 13 mm x 13 mm x 4 mm ceramic patch element, ESD circuit protection, a low noise amplifier and a SAW filter, enabling the WS1357 series to provide great out-of-band signal rejection performance, consistent and clear signal while minimizing loss-of-lock in an extremely small form factor. With its very compact 13 mm x 13mm x 5.8 mm dimensions, the WS1357 antenna series is perfectly suited for OEM applications.

Designed for easy integration into OEM handheld platforms, the WS1357 antenna integrates a highly robust ESD protection circuit, a low-noise amplifier to ensure a reliable and clear signal for the GPS receiver even in difficult conditions, as well as a SAW filter for even greater performance for hand held telematics applications where out-of-band signal rejection is required.

Applications
  • GPS Enabled Mobile Phones, PDAs & Laptops
  • Portable GPS Handhelds
  • GPS enabled M2M
  • Military and Law Enforcement Radios
  • GPS Enabled Offender Monitoring Systems
  • Asset Tracking Equipment
  • Automotive & Marine Navigation Systems
