Abstract
A tunable antenna includes separate radiator parts coupled to one another. The coupling between the parts is changed by rotating and/or displacing the parts with respect to one another such that the antenna exhibits a radiation pattern associated with a respective degree of a rotation and/or displacement. A process for manufacturing such antennas includes constructing parts for a respective antenna, coupling the parts to one another to permit them to rotate and/or displace, measuring the radiation pattern of the parts, and adjusting the radiation pattern by rotating and/or displacing the parts with respect to one another to set a nominal radiation pattern of the respective antenna formed by the parts. The couple is changed by rotation and/or displacement of the parts. A respective degree of rotation and/or displacement creates a corresponding change of a radiation pattern of the parts.
