Adaptive antennas represent a special class of antennas able to perform dynamic modification on the radiating parameter according a proper algorithm. These radiating parameters (input impedance and the radiation pattern) can be modified for different purposes. As an example, the control of the input impedance allows the selection of a particular working frequency in multi bands applications.
The control of the input impedance can be used also in wearable devices. Sure enough, such devices are exposed to user movements, dealing with compression, stretching, and bending. These deformations can cause alteration in the current distributions on the topology causing a detuning in the frequency response.
Another parameter that can be controlled in an adaptive antenna is the radiation pattern. Changes in the active beam can be exploited to receive or transmit signal toward a particular direction.
In this context, the author studied and designed different solution of adaptive antenna system
