A slot dipole antenna with a reconfigurable operating frequency is presented. The antenna comprises two pairs of slot arms. Each arm incorporates a number of varactor diodes. The antenna is capable of operating in single-band or dual-band mode. In each case, the location of these bands can be altered by varying the voltage applied to the varactor diodes. The antenna can be tuned over a wide frequency...
A simulation of reconfigurable frequency antenna is presented. The antenna is an integration of ultra-wide band antenna with a microstrip slot antenna. It has a capability to operate in ultra-wide band (0.98–12.0 GHz) and seven different narrow bands from 2 GHz to 4 GHz. Seventeen switches with eight configuration are used to select between ultra-wide band and the narrow bands. The proposed antenna...
