World's Smallest Ceramic GPS Antennas Operate at 1.575GHz

(Product News, 22 Jul 2008)

Ethertronics Inc. has launched what is claimed to be the world's smallest ceramic GPS antenna. At 4x2x1.08mm and 0.2g, 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.

Designed to operate at 1.575GHz, the antenna includes Ethertronics' patented Isolated Magnetic Dipole (IMD) technology, which enables 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 linearly polarized GPS antenna provides equivalent performance to larger circularly polarized patch antennas in moderate to high multi-path environments.

In vehicles and buildings, antenna efficiency is paramount compared to polarization, and this is where the small form factor GPS antenna delivers value-added performance. 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.
