摘要：
A dual-band frequency reconfigurable monopole antenna is presented in this paper. Reconfiguration of frequency bands is achieved using RF PIN diodes. An already published antenna design is used as a starting point and is then modified to achieve frequency reconfiguration mechanism by incorporating RF PIN diodes. The antenna resonates at center frequency of 2.4 GHz and 4.25 GHz when RF PIN diodes are switched OFF. However, RF PIN diodes ON state resulted in 1.84 and 3.66 GHz frequency bands. The 1.84 and 2.45 GHz bands are controlled by altering the electrical length of inverted L-shaped resonator. Whereas, C-shaped radiator is used to resonate the proposed antenna at 3.66 GHz and 4.56 GHz frequency bands. Overall, the simulation and measurement results showed a good agreement.
