In this paper, a novel tri-band reconfigurable patch antenna with simple structure is presented. By changing the on-off state of only two PIN diodes, the antenna can operate in three bands, namely X-band, Ku-band, and Ka-band. The overall size of the antenna is 0.24 λL × 0.5 λL...
The reconfigurable antenna comprises of a microstrip patch antenna connected to two grounded stubs via commercial graphene nanoplatelets. An applied bias voltage varies the resistance of graphene. The lengths and widths of the stubs are optimized to cause a change in reactance because of a change in...
