1. Introduction
This miniaturized 25mm square ceramic patch antenna is mounted via pin and
double-sided adhesive and is the optimal embedded antenna solution for
mobile Globalstar applications.
The antenna is tuned to a reference 60mm square ground-plane. With a peak
gain of 4dBi, the antenna exhibits excellent upper hemisphere radiation pattern
stability. Axial ratio is less than 3 on antenna operational angles, with a
minimum axial ratio of 0.54 at zenith. The SP.1615.25.4.A.02 gain and
directivity characteristics have been analyzed and approved by Globalstar.
Different device ground-planes and housing environments may require a
custom tuned antenna. Taoglas provides testing and support services to
characterize this antenna in your device and determine whether a custom
tuned solution is necessary. There is a minimum order quantity and possible
NRE for a custom solution. Contact your regional Taoglas office for support.
