Suitable applications for these antennas are mobile phones, PDAs, headsets, portable media players and other wireless equipment using GPS or Bluetooth.
Murata’s unique feeding structure makes these antennas much more stable and immune to changes in the environment, for example when the device is held in one’s hand. Murata has also developed a technology for tuning the antennas using PCB patterns and external circuits.
Designed to save space in consumer electronics applications, dimensions of each type of antenna are down to: 3.0 by 9.8 by 4.0mm (GPS On-GND type); 1.5 by 9.0 by 1.85mm (GPS GND-clearance type, exclusive of stripline circuit); 2.0 by 9.8 by 3.8mm (Bluetooth/WLAN On-GND type); or 1.6 by 3.2 by 1.2mm (Bluetooth/WLAN GND-clearance type, exclusive of stripline circuit).
