(JTI) miniature RF ceramic chip antennas are made using Low Temperature Co-fired Ceramic (LTCC) technology which has the ability to embed low and high dielectric constants inside our antenna. This enables our components to have high detuning resilience and stability over extreme temperatures (~2ppm).

Antenna Matching Network[4] If you’d like the CAD PCB layout or have any questions, contact our application engineers at https://www.johansontechnology.com/ask-a-question > 4 It is recommended that the designer leave available slots for a "pi" (or shunt-series-shunt) network. The antenna matching network values above are used when the antenna is mounted on Johanson's evaluation board. The optimal matching values will vary depending on the layout, thickness, material, etc. Go to: https://www.johansontechnology.com/tuning for more information. **johansontechnology.com** 4001 Calle Tecate • Camarillo, CA 93012, USA • +1.805-389-1166 2023 Johanson Technology, Inc.
