Abstract :
In this paper, a tunable microstrip patch antenna designed using RF MEMS switches is reported. The design and simulation antenna were performed using high frequency structure simulator (HFSS). The antenna was designed in ISM band and operates simultaneously at 2.4 Ghz and 5.7 Ghz with a -10 dB return-loss bandwidth of 20 Mhz and 180 Mhz, respect- tively. To obtain high efficiency and improve integrated ability, the high resistivity silicon (HRS) wafer was used for the antenna. The antenna achieved high gain with 8 dB at 5.7 Ghz and 1.5 dB at 2.4 Ghz. The RF MEMS DC contact switches was simulated and analysis by ANSYS software.
