Surface-mounted chip dielectric ceramic antenna for PCS phone

Abstract

In the telecommunication market smaller and lighter devices are preferred in order to miniaturize devices such as antennas, filters and duplexers, multi-layered microwave devices. The realization of these devices may be accomplished by integration of electromagnetic wave analysis technology and the manufacturing technology of dielectric materials. Furthermore, low-fire microwave ceramics which can be co-fired with good conductors such as silver metal, are needed. The microwave dielectric properties of ZnNb2O6 and Pb5Nb4O15 (ZNPN ceramics) with additives (CuV2O6, Sb2O3 and glass) was investigated. A chip antenna (7.5 mmx4.5 mmx0.8 mm) using a multilayered process was designed (1.91 GHz for PCS) and manufactured. ？ 2000 IEEE.
