Abstract
This paper presents a frequency and directivity reconfigurable antenna for millimeter-wave communication. Reconfiguration is achieved by actuating conductor matrix element with micro actuator. The conductor matrix elements are arranged in the upper conductor layer and the lower conductor layer. If a distance between the upper and the lower conductor elements is short enough, the separated conductor elements act as continuous antenna line. By actuating the conductor elements, the electrically connected antenna line is easily disconnected. Consequently, the shape of antenna is reconfigured fitting to wavelength and receiving/radiating wave direction. As a first step, we have fabricated a millimeter antenna device and measured its characteristic. We have confirmed the characteristic radiation of the millimeter wave antenna, indicating this structure is effective to control the path of millimeter current.
