Design of a compact multistubs resonator based dual-band flexible wearable antenna with low SAR for sub-6 GHz ISM applications.

ABSTRACT: In this paper, a small size multistubs resonator based flexible wearable antenna is demonstrated for dual-band operation. The proposed antenna is composed of vertically aligned multistubs resonator, a 50 Ω microstrip feed and a defected ground structure (DGS). This configuration of antenna resonates at 2.4 and 5.8 GHz Industrial, Scientific, and Medical (ISM) sub-6 GHz bands. It has a small footprint of 32 × 17 × 0.508 mm³ (0.256 λ_L × 0.136 λ_L × 0.004 λ_L at f_L = 2.4 GHz), with measured reflection coefficient magnitudes (|S₁₁|) of - 15.81 dB with bandwidth of 280 MHz (2.3-2.58 GHz) and - 33.06 dB with bandwidth of 580 MHz (5.42-6 GHz) at 2.425 and 5.72 GHz, respectively. Moreover, it has bidirectional and omnidirectional radi
