Active Band Switching Solutions

Today's new and emerging wireless applications are increasingly requiring the support of multiple frequency bands. From laptops to cellular phones to wearables, devices are expected to connect to any cellular, Bluetooth™, GSM, RFID, or other networks. These expectations present challenges when it comes to antenna design, compared to a traditional design. The simplest solution is using discrete antennas for each frequency band required in the application, which requires extra physical space. But this ultimately clashes with industry trends that prefer smaller and smaller solutions while still providing more bandwidth.

So another solution is called active band switching.Active band switching permits a single antenna element to be used by actively modifying it to work for different frequency bands on demand. It also permits active tuning to improve RF performance.
