Abstract. We report on a new reconfigurable antenna application of Scratch Drive Actuator (SDA). Micro-actuators are associated to metallic parasitic plates and pushed it toward the truncated corners of a circularly polarized microstrip patch antenna. SDAs are constructed from a standard process in which we included the fabrication of the metallic plates and the antenna. The antenna operates in the 47 GHz band and is initially circularly polarized. The use of 2 SDAs arrays moving the metallic plates close to each truncated corner of the patch enable to generate a linear polarization. This paper is organized as follows. The antenna and micro-actuators are firstly describes in section 2 nd 3 The fabrication process is detailed in section 4 Preliminarily radiation performance of the patch antenna is finally given in section 5.
