Introduction Taoglas have developed a unique ceramic miniature loop antenna series for GPS applications. At 10*3.2*3.9mm, the GLA.02 GPS 1575MHz 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 MHz antennas. Efficiencies of 40% to 90% are achievable. Peak gain of 1dBi places this antenna gain performance within the range of a much larger 15mm to 18mm patch antenna. Mechanically, this antenna does not need ground removed on the back-side of the PCB thus allowing other components to be placed there on crowded boards. 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.02 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, PND SPE-12-8-042/C/SS Page 2 of 17
