Cetiner, Member, IEEE, Gemma Roqueta Crusats, Student Member, IEEE, Lluís Jofre, Senior Member, IEEE, and Necmi Bıyıklı, Member, IEEE Abstract—A new kind of double- and single-arm cantilever type DC-contact RF MEMS actuators has been ... RF MEMS Based Reconfigurable Rectangular Slotted Self Similar ... A wide band Frequency Reconfigurable Rectangular Slotted Self Similar Antenna has been proposed in this paper. The rectangular slotted patch is repeated for two iterations at different scales and is separated by means of Radio Frequency Micro Electro Mechanical Systems (RF MEMS) switches in order to provide reconfigurability. Pattern and Frequency Reconfigurable Annular Slot Antenna ... The reconfigurable ASA proposed in this paper operates at three frequencies with a central frequency at 5.8 GHz, and it also Index Terms—Annular slot antenna (ASA), frequency reconfig- has a reconfigurable radiation pattern that can position a null urability, pin diode, reconfigurable antenna, reconfigurable radia- tion pattern, slot antenna.

Design and Implementation of Reconfigurable Antenna redistribute the antenna currents. Radio frequency micro-electromechanical systems (RF-MEMS) have been proposed for integration into reconfigurable antennas since 1998 [5]. Many designs have resorted to RF MEMS to reconfigure their performance. RF MEMS based reconfigurable antennas rely on the mechanical movement of these switches to achieve RF MEMS antennas for wireless applications - ScienceDirect The combination of RF MEMS technology with antenna structures follows different approaches which vary depending on the antenna size and frequency as illustrated in Fig. 6.1.. The first technological approach consists of manufacturing the antenna structure in a first step, then adding the RF MEMS devices in subsequent steps using wire-bonding and conductive epoxy.
