A novel frequency‐reconfigurable patch antenna is proposed and analysed using the finite‐difference time‐domain (FDTD) method. The simulated results indicate that the antenna is capable of shifting its operating frequency over a one‐octave bandwidth from 0.6 GHz to 1.2 GHz with the radiation pattern essentially unaffected by the frequency tuning.
