GPS DIELECTRIC PATCH ANTENNA

DESCRIPTION

The TOKO DAK1575MS50T is a low profile, dielectric

antenna element specifically designed for 1575.42 MHz L1

GPS applications. The flat patch antenna incorporates a

rectangular micro-strip design for GPS C/A right-hand

circular polarization wave reception. The DAK1575MS50T

has excellent stability and sensitivity through the use of

high performance ceramic materials well suited for GPS

applications and ships with double-sided adhesive tape for

ease in mounting to the ground plane.
