| Summary: | Abstract—In this work, two adjacent patches and MEMS
switches are proposed a reconfigurable antenna that is
capable of operating at several frequencies. Optimization of
wing patches is done to obtain more than three resonant
frequencies of the antenna by selecting the MEMS cantilever
bridge materials. The study shows that the material of MEMS
switches has influenced the performance of the antenna. SiN
as MEMS bridge material makes the antenna to operate at
16.76 GHz, 23.56 GHz and 27.7 GHz at “OFF” states and at
23.5 GHz at “ON” states of the MEMS switches. A comparative study has done for Alumina, SiN, GaAs and Teflon as MEMS bridge materials. Further re-configurability can be obtained by varying the MEMS switch position. The
design is performed by using 3D electromagnetic simulator
HFSS considering ideal MEMS switches. |
