Component selectionDesign tips

Characteristics

The overview shows typical components for the design of radio interfaces with chip antennas. This includes a chip antenna, matching network and UMRF connector, as well as a radio module.

The generated near-field by the integrated chip antenna is significantly influenced by the immediate environment. The main influencing factors are metals, batteries/accumulators, casings and human bodies. The position of the chip antenna on the PCB and the PCB size/geometry may significantly influence the antenna characteristics. The PCB interacts together with the chip antenna and combined they form the radiating structure.

Depending on the application, the chip antenna may be out of tune by the influencing factors and the PCB configuration. With the help of RF inductors and RF capacitors, which form a matching network, the chip antenna can be matched to the required frequency range.
