چکیده
This paper presents a new reconfigurable antenna based on coplanar waveguide (CPW). The design for reconfigurable antenna is based on monolithic microwave integrate circuit (MMIC). This scheme combines a CPW antenna and switchable resonator radio frequency micro-electromechanical system (RF-MEMS). The resonator RF-MEMS presents a meander inductor structure and tuning capacitor controlled by the applied DC voltage. This component can be used for the System on the Chip (SoC). Moreover, this device presents a compactness characteristic and the possibility to operate at high frequencies. The switch element allows changing the frequency band and the resonant frequency easily. The simulation results are shown between 10 and 40 GHz. The presented reconfigurable antenna can cover five bands: (26, 26.6) GHz, (26.4, 27.3) GHz, (27.3, 28) GHz, (29, 30.1) GHz and (30.13, 30.7) GHz. All simulation results were made by the High Frequency Structural Simulator (HFSS) software and validated by Computer Simulation Technology Microwave Studio (CST MWS). Keywords—RF-MEMS; CPW; Bandwidth; Meander; Resonator; Frequency reconfigurable antennas and MMIC

Abstract: A novel reconfigurable patch antenna for frequency diversity is proposed by reconfiguring its geometry using tree rectangular tapes that are connected to the patch via six RF MEMS switches. So switching between the different frequency bands is achieved by using capacitive series RF-MEMS switches. The antenna was designed to operate at 2.6 GHz, 3.1 GHz, 3.5 GHz and 5 GHz.
