Tuning multilayer chip antennas can be a simple process when the basics of impedance measurement and matching are understood and a logical iterative process is followed.
Würth Elektronik not only offers the necessary components for a perfectly adapted antenna network, but also supports you with the design. Our RF design engineers support you with antenna adjustment and performance optimization during the design and test phase of your wireless application.
The WE-MCA multilayer-chip-antenna offers a very diverse portfolio of applications when it comes to wireless data transmission, including Bluetooth, ZigBee, GSM, NB-IoT and WLAN.
With the help of the Smith diagram, the antenna impedance, consisting of resistive and reactive components, can be graphically represented.
In a perfectly matched antenna network, the impedance at the operating frequency of the antenna is in the middle of the Smith diagram and therefore 50 Ω. This can be achieved with the help of RF inductors and / or capacitors.
A pi network is particularly useful for this purpose as it can be used very flexibly to tune the antenna to 50 Ω from almost any other value.
There should be no ground plane under or above the antenna. For more information, see our application note WE-MCA Multilayer Chip Antenna Placement & Matching
For optimal support, we first need the schematics, circuit and frequency information. For a better service we also need some additional information and equipment from the customer:
This varies from application to application and depends on the complexity of the project. Generally, the process of antenna customization takes 2-3 weeks.
A frequency range of 400-6000 MHz is possible.
