Abstract

A design technique of Inverted-F Antenna (IFA) that can be easily applied to conventional antenna is presented for the Specific Absorption Rate (SAR) reduction. The proposed IFA has the characteristic of reducing only the effect of electromagnetic wave absorbed by the human body while maintaining good radiation performance compared to conventional IFA. The proposed IFA operates at 1.7 GHz, allocated in the GSM frequency band, and the solid phantom is used to evaluate the electromagnetic wave absorbed in the human body as an equivalent model of the human body. The size of proposed IFA is 90 mm × 50 mm including the size of the FR4 substrate whose thickness is 0.6 mm. The simulations are performed for analyzing the relationship between the distributed-current characteristic and SAR. The SAR1g value obtained by proposed IFA decreases about 11 % compared to the conventional IFA.
