ABSTRACT:
A small and durable antenna for use with radio and microwave communications is formed as a helical conductor contained in a multilayered non-ferrite ceramic chip. The dielectric constant of the ceramic is selected to match the antenna to its operating frequency, which may be in the range of 0.5 to 10.0 Gigahertz. A process for making such antennas is also disclosed. The antenna may be used in portable terminals and other devices requiring small, durable and inexpensive antennae.
