We present a reconfigurable spiral antenna for use in adaptive MIMO systems. The antenna
is capable of changing the sense of polarization of the radiated field. It is fabricated by using
an RF-MEMS technology compatible with microwave laminate substrates developed within
the author's group. The proposed antenna structure is built on a number of rectangular-
shaped bent metallic strips interconnected to each other with RF-MEMS actuators. Two
senses of polarization, RHCP and LHCP, are achieved by configuring the physical structure …
