1. Introduction

Taoglas has developed a unique ceramic miniature loop antenna series for GPS

applications. At 5.0*3.0*0.5mm, the GLA.01 GPS Loop antenna is a miniature edge

mounted antenna designed for small space requirements. The radiation pattern is

more omni-directional than traditional patch antennas. The GLA loop antenna series

show at least three times the efficiency of traditional linear polarized 1575.42MHz MHz

antennas. Efficiencies of 40% to 90% are achievable. A peak gain of 2.5dBi places this

antenna's gain performance within the range of a much larger 15mm to 18mm patch

antenna.

Mechanically, the GLA.01 at only 0.5mm in height has a very low profile, and with a

footprint of 6.0 x 5.5mm needs less space on the board. It does require clearance of

6.0 x 5.5mm. Based on the loop effect, this antenna works best when placed on the

center of the edge of the board, but can still work better than traditional linear

polarized chip antennas even when placed at corners as a substitute.

The GLA.01 is delivered on tape and reel and now allows M2M customers to use an

omni-directional antenna in devices where orientation of the product is unknown.

Applications

*Navigation or position tracking systems

*Hand-held devices when GPS function is needed, e.g., smart phone. PDA
