Abstract :
The performance of the RF MEMS reconfigurable antenna depends on MEMS material. Alumina as a MEMS switch material has performed better frequency response compared to other materials as a MEMS switch. The proposed reconfigurable antenna can be operated as a triple-band antenna operation at 17.21, 23.54 and 29.27 GHz with return loss -12.04, -19.37 and -17.34 dB, respectively. The design is performed using 3D electromagnetic simulators considering ideal MEMS switches. There is no shift of resonance frequency that occurred at 23.54 GHz when both MEMS switches are either OFF or ON.
