چکیده

The tunable characteristics of RF MEMS (Microelectromechanical Systems) components enable their integration with antennas providing numerous advantages such as reconfigurability in polarization, frequency, and radiation pattern [1]. Furthermore, the monolithic fabrication of these components with antennas can reduce parasitic effects, losses and costs. This paper presents two tunable frequency antennas integrated with RF MEMS capacitors to tune the operating frequencies. The antennas are designed using Ansoft HFSS, prototypes are fabricated and experimental results are compared with the simulations. Approximately 1 GHz tunability for the desired frequencies has been achieved.

Reconfigurable Microstrip Patch Antenna for Frequency Diversity Using RF MEMS

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.
