1. Introduction
This 18mm*18mm square ceramic GPS/GLONASS/BEIDOU patch antenna's wide band of
operation leads to excellent gain and radiation pattern stability on all three GNSS system
bands.
Compared to using a smaller antenna, this will translate into the GNSS system having much
higher location accuracy, improved reliability of lock in urban areas, better signal reception,
with more satellites acquired and a quicker time to first fix.
The patch is mounted via pin and double-sided adhesive.
