1.Introduction

Taoglas have 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. Peak gain of 2.5dBi places this antenna 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 centre of the edge of the board, but can still work better

than traditional linear polarized chip antennas even when placed at corners as

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,
