Würth Elektronik has announced that it now offers developers wanting to use WE-MCA series chip antennas a free matching service. WE-MCA are compact SMT-mountable multilayer ceramic chip antennas available in numerous single and dual band versions.

The antennas therefore provide a space-saving solution for GSM-900, WiFi, Bluetooth, GPS/GNSS, ZigBee or 4G/LTE enabled devices and facilitate compact designs for IoT and smart home applications. The challenge here: The performance of the applications also depends on the placement of the antenna on the PCB and effective impedance matching.

Würth Elektronik advises on the layout and selection of suitable inductors and capacitors to eliminate disturbing influences from the surrounding environment.

The trend towards miniaturisation of wireless communication devices is reducing PCB size and increasing component density. The demands placed on RF front-end design are growing, as an antenna is a function of its surroundings and gets influenced by almost everything e.g. rubber, plastic, and metal, human body. Developing companies, without access to their own high-frequency specialists, can now benefit from the free consulting services offered by Würth Elektronik.

Würth Elektronik keeps the components needed to develop an antenna matching circuit available in the stock - also as part of the free sample service. These include WE-BAL Multilayer Chip Balun, WCAP-CSRF MLCCs, WE-KI ceramic inductors, as well as low-pass and bandpass filters.
