The article reveals the design of a metamaterial cell inspired triple band antenna for DCS 1800, PCS 1900, WCDMA, Bluetooth, WLAN 2400, WiMAX 2.5, and WLAN 5 GHz frequency band applications. The overall antenna size is 48 × 48 × 1.575 mm 3 where the electrical dimension is 0.26 λ × 0.26 λ × 0.0084 λ at 1.6 GHz lower frequency band. The proposed antenna consists of a microstrip feed line and metamaterial unit cell providing a negative index of refraction, which indicates both negative magnetic value of permeability and negative electrical value of permittivity. The proposed antenna achieves triple −10 dB measured impedance bandwidth of 370 MHz (1.6–1.97), 380 MHz (2.34–2.72), and 1.48 GHz (3.89–5.37). The measured gain of the proposed antenna at 1.9 GHz is 1.64 dB, 2.45 GHz is 2.07 dB, and 5 GHz is 4.06 dB with radiation efficiency of 66.2%, 77.15%, and 87.6%, respectively. © 2016 Wiley Periodicals, Inc.
