ABSTRACT: This paper presents a modification of
an existing cognitive antenna design which contains two antennas: one is a sensing
that covers the band from 1 - 11 GHz and the
other is a hybrid triangular reconfigurable antenna. Two antennas are combined
together to create a new design which called Cognitive Antenna. The new shape
of the reconfigurable antenna will affect the cognitive antenna so as to work
at two different frequencies via rotation by 180°. At each rotation, the antenna takes single
frequency from number of possible frequencies that sensing antenna would find.
