Metamaterial Inspired Compact Penta-band Antenna For Wi-MAX, WLAN, Satellite band and X-band Applications

摘要

A penta band loaded with complementary octagonal split ring resonator (COSRR) is reported. The antenna has a size of 0.16λl × 0.16λl × 0.01λl, at lower frequency band of 3.33 GHz. The antenna consists of a rectangular slot is placed in the ground plane and complementary octagonal split ring resonator in the radiating patch, which independently resonates lower frequency at 3.33 GHz and other four bands at 5.01GHz, 5.28GHz, 7.46GHz, and 9.48GHz respectively. The designed antenna operates at 3.33, 5.01, 5.28, 7.46 and 9.48 GHz. It is observed that the proposed structure is having better impedance matching, gain, efficiency and stable radiation pattern at targeted frequencies and used for Wi-MAX, WLAN, Satellite band and X-band applications.
