Design and Development of Self-Complementary DNA Structure-based Frequency Reconfigurable Antenna
Nature-inspired patch antennas are gaining attention in wireless applications. A novel self-complementary Deoxyribonucleic Acid (DNA) structure-based frequency reconfigurable antenna is proposed in this work. DNA itself follows the golden ratio. The structure of the DNA-shaped antenna is modelled using Fibonacci numbers. The structure dimensions are 80 × 80 × 0.787 mm3. Rogers RT Duroid 5870 with a dielectric constant of 2.33 is used as a substrate. Techniques like the placement of the parasitic patch and Defected Ground Structure (DGS) are implemented and analyzed for gain enhancement. Parametric analysis has been carried out to achieve better radiation characteristics. The antenna is made reconfigurable by incorporating two PIN diode switches. The designed structure covers a wide band from 4.86 GHz to 6.12 GHz (WLAN) during an OFF-ON state. 0.988 GHz (Sub 1 GHz) and 4.58 GHz (5G) (dual band) are the resonating frequencies of the ON-OFF state. For the ON-ON state, the resonating frequencies are 2.67 GHz (WiMAX), 3.36 GHz (LTE), and 4.76 GHz (5G) (triple band). The proposed structure offers acceptable radiation performance. Fabrication and testing are done to validate the results. The simulated findings and the measured results agree quite well.
