Abstract
A complementary staked microstrip antenna with a modified Minkowski fractal shaped defect is presented which has a wide bandwidth of 1.8–6.4 GHz with a fractional BW of 89.1%. The concept of the complimentary stacked parasitic fractal patch has been incorporated to enhance the impedance bandwidth in comparison to the conventional stacked patch antenna. The antenna has a dimension of 42 × 55 × 4.8 mm3, which is printed on a low cost FR4 substrate of dielectric constant 4 and a height of 1.6 mm. The gain of the antenna varies from 5 to 7 dBi throughout the operating band. Simulated and experimental characteristics of the antenna are in good agreement. The proposed antenna can be a potential candidate for wideband communication systems and also capable to operate satisfactorily in 3.3–3.7 GHz (WiMAX), 3.7–4.2 GHz (C-Band), and 5.15–5.825 GHz (WLAN) frequency bands. © 2014 Wiley Periodicals, Inc.
