Ceramic Chip Antenna Theory

Ceramic chip antenna antennas are available at mouser electronics.

Ceramic chip antenna theory.

Area around and beneath the. 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. This enables them to have great detuning resilience and extreme temperature stability 2ppm behavior. In summary a ceramic chip antenna is one half of the overall design considerations and the pcb ground plane is the other.

2 theory printed and surface mountantennas have certain common properties. Mouser offers inventory pricing datasheets for ceramic chip antenna antennas. This application note only describes pifa and ceramic antennas because they are the most common low profile smallest and inexpensive types available. 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 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. The actual oscillation mode will be defined by the geometry of the antenna. Antenna to be made small while keeping a high resonant frequency. 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.

Chip antenna vishay s chip antennas include parts with uhf band coverage for mobile devices as well as surface mount ceramic chip parts for 868 mhz 915 mhz 1 575 ghz 2 4 ghz and 5 0 ghz applications. In a medium having high permittivity the wavelength is shorter than in the free space. Chip antennas are the best alternative when a larger sized antenna is impractical. In the simplest case the geometry will be two parallel plates spaced.
