Ceramic Chip Antenna Theory

One means of creating an antenna which can be integrated into a pcb would be the use of fractal geometry.

Ceramic chip antenna theory.

Mouser offers inventory pricing datasheets for ceramic chip antenna antennas. Ceramic chip antenna antennas are available at mouser electronics. This enables them to have great detuning resilience and extreme temperature stability 2ppm behavior. 2 theory printed and surface mountantennas have certain common properties.

Antenna to be made small while keeping a high resonant frequency. The actual oscillation mode will be defined by the geometry of the antenna. Johanson miniature rf ceramic chip antennas are made using low temperature cofired ceramic ltcc technology which has the ability to embed low and high dielectric constants inside our antenna. This application note only describes pifa and ceramic antennas because they are the most common low profile smallest and inexpensive types available.

In a medium having high permittivity the wavelength is shorter than in the free space. This way the antenna sees the structure that is comparable in the size to the wavelength in the medium while being very small compared to the free space wavelength. In the simplest case the geometry will be two parallel plates spaced. The chip antennas use some material usually ceramic that has high permittivity and low losses.

A fractal is a complex pattern constructed from the repitition of a simple shape which maximizes the length or increases the perimeter of the material thats radiates an electromagnetic signal. Area around and beneath the. Furthermore like a monopole antenna a ceramic chip antenna s tuning as well as radiation pattern is dependent on the ground plane s shape and size. Dielectric resonator antennas commonly referred to as chip work by creating a standing wave of electrical field of a given frequency technically it is a cavity resonator where the cavity between conductive surfaces is filled by the ceramic core.
