This paper picsenls a reconfigurable dual-band 4.86 and 8.98 GHa dipole anlenna on silicon using scrics MEMS switches. The effccts of series MEMS switches on the antenna performance are studicd. Thc design is performed using thc 3D electromagnetic simulator HFSS'. Using the dcsigned series MEMS switches, thc obtained antenna m u m loss is -lO.ZdB and -21.6dB, at the lower and uppcr frequencies, respectively. However, comparable to the case of ideal switches, a frequency shiA of0.4% and of 2.8% at the lower and uppcr frcqucncics, respecliveiy, is observed. The antenna, including the MEMS switches, has bandwidth of 1.9% and 13.6% at the lowcr and upper frequencies, respectively. The antenna directivity is 2 dB at the lower frequency, and is 3 dB at the uppcr frequency.
