ABSTRACT:
Electromagnetic signal emitting and/or receiving device and corresponding integrated circuit. The electromagnetic signal emitting and/or receiving device defines a minimum operational bandwidth and includes one or several arrays of antennas, each having at least one antenna, and which generate an output signal corresponding to the output signal generated by an hypothetical antenna equal to this antenna, when the hypothetical antenna is performing a periodic movement, preferably a rotation or combination of rotations. The periodic movement must have a frequency higher than a minimum operational bandwidth. In this manner the directivity of the antennas can be affected by changing their radiation pattern, being possible to obtain high directivity devices. The periodic movement can be replaced by an array of fixed antennas oriented in space and sequentially connected by miniaturized relays.
