1. Introduction
Taoglas have developed a unique ceramic miniature loop antenna series for GPS applications. At
5*3*0.6mm, the GLA.01 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 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 0.6mm in height has a very low profile, and with a footprint of 6*5.5mm
needs less space on the Board, it does require clearance of 6*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.
1.1 Applications
2.0 Key Performance Indicators
The antenna performance was measured with the GLA.01 mounted on an evaluation board (80*40mm
ground plane) with SMA(F) connector.
* Center frequency will be offset to working frequency according to the conditions of user’s Ground
plane and radome.
**The data was measured by A Test Lab Techno Corp. (CTIA Authorized Test Lab).
*navigation or position tracking systems
*Hand-held devices when GPS function is needed, e.g., Smart phone. PDA, PND
