A compact dual wideband metamaterial antenna designed for wearable application is presented in this communication. A metamaterial resonator structure that works as a radiator resonates in dual-band frequencies. The antenna is operated in the frequency spectra of IEEE 802.11 a and b/g/n WLAN, WiMAX 2.3 and 5.5 GHz and GSM 1800 MHz bands. The antenna has wide measured bandwidth from 1.6 to 2.56 GHz (46%) and 4.24 to 7 GHz (49.11%) with average measured gain of 1.6 dB in the lower band and 5 dB in the upper band. The structure of the antenna is examined analytically with different bending dimensions and human body effect. The antenna geometry is fabricated on a jeans material and also measured on different body locations to analyze its performance. The maximum patch dimension of the proposed design is 0.1 λ × 0.1 λ mm2 with respect to the lower band. Excellent agreement is found between the simulated and measured results.
