US 2006/0152415 A1 · Ceramic chip antenna

Abstract

A ceramic chip antenna for transmitting and receiving wireless signals. The antenna includes a substrate and a conductor. The substrate is made of sintered ceramic material with a low dielectric loss and a high dielectric constant. A pair of concavities is cut from both longitudinal ends of the substrate. The conductor is made of metal with a high Q factor as well as a good anti-oxidization property, being formed on surfaces of the substrate by means of mask etching or printing technology. The conductor has a circuit portion disposed on surfaces of the substrate in a meandered or helical manner, and two conducting electrodes disposed at the two concavities of the substrate and connected by the circuit portion.
