Recently the development of information-intensive society around us is quite remarkable, making many innovative systems indispensable for our daily lives. There are, e.g., the explosive development and diversification of mobile phones, wireless communications technologies and car navigation systems for automobiles, and the domestic penetration of short-distance wireless communications equipment that are in conformity with Bluetooth or IEEE 802.11a and 11b. Antenna is one of the key components supporting the wireless technologies. Furukawa Electric has developed a high-performance ultra-compact chip antenna for the 2.4~2.5 GHz band. The antenna features the use of a functional resin material for its dielectric, and has been confirmed to be suitable for mass production ensuring high long-term reliability.
