A K‐shaped fractal dielectric resonator antenna with CPW feed is proposed. Self‐repetition property of fractal configuration has been utilized to bring higher order modes together to achieve wide percentage bandwidth. Antenna is simulated and optimized using high‐frequency structure simulator (HFSS) and fabricated using Roger RO4350b as substrate and Roger RT/duroid 6010 as dielectric resonator. The overall antenna size is 42 × 54 × 6.524 mm 3 . Resonant frequency behavior of the fractal iterations leading to wide band operation is presented to provide insight to the design and functionality of K‐shaped resonator. Proposed antenna possesses wide percentage bandwidth of 90.65% from 3.8 to 10.1 GHz, high radiation efficiency that is >92% and appropriate gain, making it potential choice for wide‐band wireless applications. © 2016 Wiley Periodicals, Inc.
