Abstract
A novel metamaterial (MTM) structure is employed to tilt the beam and increase the directivity of a wearable antenna at 5.2 GHz which belongs to the industrial, scientific, and medical (ISM) sub-channels. In this design, a standard jean textile which is a wearable and flexible material is utilized as the substrate of the antenna. The standard denim fabric has a dielectric constant of 2.17, a thickness of 3.175 mm, and tan (δ) = 0.002. With using this design, the radiation beam of the antenna is guided in the desired direction for healthcare applications. The simulated results demonstrate that the radiation beam is tilted by 9o in the E-plane. The measured gain at 5.2 GHz is equal to 6.35 dB. Also, the specific absorption rate (SAR) provides the perfect necessity for medical applications. The results display that the recommended antenna is a promising candidate in biomedical technology.
