Introduction

This series of ceramic miniature loop antennas is designed for GPS/GALILEO applications. The GLA.01 GPS/GALILEO loop antenna measures 5.0×3.0×0.5mm and is a miniature edge-mount antenna suited for space-constrained applications. Its radiation pattern is more omnidirectional than that of conventional patch antennas. The efficiency of this loop antenna series is at least three times that of conventional linearly polarized 1575.42MHz antennas, achieving efficiencies of 40% to 90%. The peak gain of 2.5dBi delivers gain performance comparable to much larger 15mm to 18mm patch antennas. Mechanically, the GLA.01 has a height of only 0.5mm with an extremely low profile, occupying a board footprint of 6.0×5.5mm, with a clearance area of the same dimensions required. Based on the loop effect, the optimal placement is at the center of the PCB edge; however, even when placed at a corner as an alternative, its performance still surpasses that of conventional linearly polarized chip antennas. The antenna is supplied in tape-and-reel packaging, enabling omnidirectional antenna functionality in devices where product orientation is unknown. As long as it is properly soldered via SMT, mounting the antenna in any orientation will not result in performance degradation.
