Abstract
In this paper, authors propose electrically small wearable tunable antenna that could conform to a smartwatch dial. This antenna has been designed with a clear target of fitting it into smartwatch. Proposed antenna has been tuned to human body parameters and resonates at 2.4 GHz band. For this, authors have utilized a human body model they have published previously. The final antenna design has been evolved from simple monopole and a shorting pin has been added to improve the return loss. Antenna PCB is fabricated using FR4 substrate of 1.6 mm height and radius of 17.5 mm. Return loss at 2.4 GHz is -24 dB and VSWR value 1.2 is observed. Authors can achieve gain of 0.5 dB. Simulated and measured results of antenna are found in agreement.
