Antenna Matching and Characterization Support

The matching of Multilayer Chip Antennas can be a simple process when the fundamentals of impedance measurement and matching are understood and a logical iterative process is followed. Würth Elektronik is offering not just the components for a matched Antenna Network, we can also support in the process of designing. Our RF-Design engineers will assist you with antenna matching and performance optimization during the design and testing phase of your wireless product.

The WE-MCA Multilayer Chip Antenna has a very diverse applications portfolio when it comes to wireless data transfer, including Bluetooth, ZigBee, GSM, NB-IoT and WLAN.

How Antenna Matching works

With the help of the Smith chart, the antenna impedance, consisting of resistive and reactive components, can be easily represented graphically. In a perfectly matched antenna network, the impedance at the operating frequency of the antenna is in the middle of the Smith chart and therefore at 50 Ω. This can be achieved by using RF inductors and/or capacitors. A pi network is particularly useful for this purpose, since it can be used very flexibly for antenna tuning at 50 Ω from almost any other value.

When in design phase what rules should be kept in mind regarding the RF front-end?

How far away should the antenna be from the metal/ground plane?

There should not be any ground plane below or above the antenna. For more information please have a look at our application note WE-MCA Multilayer Chip Antenna Placement & Matching.

What do I need to provide in order to avail this support?

For optimal support, we need first the schematics, circuit and frequency information. For a better Service, we need also some more information and equipment from the customer:

How much time does it take for the whole process?

It varies from case to case depending on the complexity of the project. Generally it takes 2-3 weeks for antenna matching process.
