Ethertronics Delivers World's Smallest Ceramic GPS Antennas

Ethertronics Inc. has introduced its ceramic GPS antenna. At 4mm x 2mm x 1.08mm and 0.2 grams, the Ethertronics' Savvi Embedded Ceramic Antenna is designed for integration into many small form factor devices including GPS-enabled mobile phones, personal media players and navigation equipment without sacrificing performance and efficiency.



Designed to operate at 1.575 GHz, this antenna includes Ethertronics' patented Isolated Magnetic Dipole (IMD) technology, enabling high-isolation characteristics, immunity to frequency shifts and de-tuning resistance in a small footprint. The antenna's efficiency is 58 percent with an operating bandwidth greater than 40MHz at a -7dB return-loss figure. The Ethertronics' linearly polarized GPS antenna provides equivalent performance to larger circularly polarized patch antennas in moderate to high multi-path environments. By utilizing Ethertronics IMD technology, this antenna inherently provides high selectivity which eliminates the cost and space for additional, complex filters that are otherwise needed to remove UMTS- or AWS-band signal interference. The Ethertronics' Savvi Line also includes the following ceramic antennas: WLAN, WiMAX, PCS/WiMAX, compact and standard Bluetooth, standard GPS, and compact GPS/Bluetooth.
