Abstract
The ever-growing miniaturization of electronic devices is foremost due to a wide range of
changes in shrinking the wearable devices. This article focuses on a small, wearable antenna with
dual bands for 5G and Wi-Fi communications. The Frequency Selective Surface (FSS) is made of
denim Jean and has a top- loaded stubs-inspired radiator and a modified ground plane structure to induce the resonance frequencies at 3.5 and 5.8 GHz within a compact 31.5 mm × 26
mm size. With the FSS integrated antenna, you can cover the N-78 5G band-width of 620 MHz
(S11 × −10dB) in the 3.28–3.9 GHz range, as well as the Wi-Fi bandwidth of 600 MHz (S11 × −10
dB) in the range of 5.65–6.25 GHz. The antenna presented has a peak gain of 7.07 dB at 3.5 GHz
and 6.02 dB at 5.8 GHz. This antenna is mounted near a human arm model lowering the Specific
Absorption Rate (SAR) to 0.370W/kg at 3.5 GHz and 0.870W/kg at 5.8 GHz. The simulated values
are validated with measured results and are suitable for body area communication. The designed
FSS antenna provides stable impedance bandwidth for conformal applications with enhancing
radiation performance.
