Miniature gps antenna gets surface mounted

Sarantel's GeoHelix gps antenna offers benefits over patch antennas.

A surface mount version of Sarantel’s GeoHelix miniature gps antenna has been launched. The GeoHelix S is said to have a number of benefits over conventional patch antennas. According to Sarantel, it offers a 3dB contour at up to 120O allowing it to see more satellites simultaneously, and as a balanced antenna, weak signals from satellites won’t be detuned when integrated into a handset which is close to human tissue, such as a hand or head.
The GeoHelix S, measuring 48.5 x 14.6 x 13mm, operates on the gps L1 band at 1575.42MHz. It incorporates a 24dBi low noise amplifier and draws 12mA from a 3V dc power supply. It will be supplied in edge mount and flex mount formats, the former with a choice of sma or mcx connectors, and the latter with a 100mm cable terminated in an mcx, mmcx, sma, ssmt or Hirose h-fl connector.
