| Popis: | In the present article authors propose the design and analysis of an octagonal shape multiband metamaterial loaded antenna with implementation of hybrid fractal geometry for wireless applications. Multiband features in the antenna structure is realized by applying the slotted and hybrid fractalization of Moore and Koch curve approach in radiating section along with introduction of two metamaterial SRR cells. The frequency band reconfigurability characteristics in proposed design is achieved by placing the PIN diode inside the connecting strip between the central hybrid fractal geometry and feedline. During forward bias condition of PIN diode antenna structure resonates at hepta (seven) band mode at WiMAX (3.5 GHz)/Lower C-band (4.41 GHz)/WLAN (5.4/5.8 GHz)/Lower X-band (8.26 GHz)/Upper X-band (10.48 GHz)/Lower Ku-band (13.35 GHz)/Middle Ku-band (14.42 GHz) wireless standards with S 11 ≤ −10 dB. Proposed antenna represent the hexa and hepta band features during reverse bias (OFF-state) and forward bias condition (ON-state) of PIN diode respectively. A stable and consistent radiation patterns, appropriate impedance matching and an acceptable gain are achieved at all the operating frequencies of the proposed antenna. |
