MurataElectronics North America has introduced a series of standardized antennas for GPS, Bluetooth, ZigBee, and wireless local-area network (WLAN) 2.45-GHz applications. The LDA31Hand ANC series platform antennas are tailored for devices such as mobile phones, PDAs, headsets, and portable media players.

The standardized parts require very little design resources and achieve high-performance levels in a tiny package size based on Murata’s high-Q dielectric ceramics. Both on-ground and ground-clearance types are available. Dimensions of each type of antenna have been reduced to: 3.0 by 9.8 by 4.0 mm (GPS on-ground type); 1.5 by 9.0 by 1.85 mm (GPS ground-clearance type); 2.0 by 9.8 by 3.8 mm (Bluetooth/WLAN on-ground type); and 1.6 by 3.2 by 1.2 mm (Bluetooth/WLAN ground-clearance type).

Murata’s platform antenna can be optimized on a customer’s board by using a specific land pattern and a grouping of external inductors and capacitors. Additionally, the company’s unique feeding makes these antennas much more stable and immune to changes in the environment near the antenna. The company has also developed a standard process for tuning the antennas using printed-circuit board (PCB) patterns and external circuits.

Lead time for the antennas is 10 to 12 weeks. Samples are available for $0.75.
