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.
