Miniaturized Ceramic Antennas Offer Flexible Placement In GPS, Bluetooth Devices

Fri, 04/04/2008 - 7:58am

Ethertronics introduced two miniaturized ceramic antennas: a GPS/Bluetooth version and a GPS antenna, which is said to provide high efficiency while minimizing ground clearance and component “keep out” areas. Designed to address the challenges associated with incorporating multiple RF-functions into mobile devices, both antennas include the company's Isolated Magnetic Dipole (IMD) technology. The GPS antenna measures 8 mm × 3 mm × 1.3 mm, and the selectivity of the antenna’s RF response is said to eliminate the need for additional filters for removing UMTS- or AWS-band signal interference. Measuring 12 mm × 3 mm × 1.3 mm, the dual-band, dual-feed GPS/Bluetooth combination antenna uses the RF-isolation properties of its IMD technology and combines two secondary antennas into a single small package that is a 35 percent size reduction from an earlier model while maintaining each separate antenna’s performance characteristics. Given their size and ability to resist de-tuning, a single ceramic antenna can be successfully placed into PCBs of various sizes or in many different locations on the PCB without impairing reception.
