“…The antenna is placed on the three‐layered cylindrical shaped model and the human body dielectric properties are assigned to the cylinder layers. To analyse the SAR values, the antenna is placed on the three‐layered phantom model and performed the SAR analysis 19‐23 . In Figure 18B antenna and AMC structure are bent with an angle of 30°.…”

This article presents the design of low-profile single band antenna on flexible substrate material. The proposed antenna is designed on the polyimide substrate with overall size of 30 mm × 30 mm × 0.2 mm. The designed antenna operates in the frequency range of 5.71 to 5.99 GHz with impedance bandwidth of 4.8% and covers the Industrial Scientific Medical band for medical body area network applications. The antenna is enabled by placing artificial magnetic conductor (AMC) with two by two array elements under the ground plane. The AMC structure acts as an isolation for the ground plane and main radiator to reduce back radiation. Compared with literature in the wearable antenna designs, the proposed antenna is compact in structure with high gain of 8.31 dBi with AMC-backed structure. The specific absorption rate values are observed by placing the antenna on the three-layered human body model and the observed values are 1.26 and 0.72 W/Kg without AMC and with AMC, respectively. The obtained values are in conjunction with ICNIRP standards, that is, 2 W/Kg should be averaged over 10 g of tissue. The proposed antenna can be used for the smart clothing and wearable electronics applications.

“…Article 1 has proposed a wearable, flexible reconfigurable antenna with enhanced radiation and reduced specific absorption rate (SAR). Article 2 has reported a low‐profile, high gain slotted monopole antenna for reducing SAR. In Reference 3, a flexible, compact slotted Artificial Magnetic Conductor (AMC) for enhancing gain up to 4.8 dB has proposed.…”

This article presents a dual‐band shared‐aperture antenna. The lower‐band antenna consists of two printed dipoles operated in a 1.6‐2.4 GHz frequency band. An artificial magnetic conductor (AMC) is used to reduce the lower‐band antenna profile. The higher‐band antenna consists of 4 × 2 aperture coupling patches operated in 5.3‐7.1 GHz frequency band and placed between the antenna ground plane and the AMC. The AMC elements act as a bandpass frequency‐selective surface for the higher‐band antenna. Simulated and measured results show that the proposed antenna has 40% and 29% impedance and 3‐dB gain bandwidths for the lower‐band and higher‐band antennas, respectively, and port isolation of less than −20 dB.
