The antenna proposed in this article is structured on a Rogers RT5880 (lossy) substrate holding two grounds parallel on two opposite planes, one adjacent to the transmission path feeding the fractal patch. These grounds are named as parallel − plane grounds (PPGs). The fractal antenna features a compact size of 17.7 × 9 . 8 × 1.575 mm 3 unveiling a −10 dB impedance bandwidth of 19.5 GHz (3.2 GHz–22.7 GHz). The iterative ratio, r has an impact on the impedance bandwidth resembling other design parameters. A transient bandwidth enhancement is achievable by keeping the iterative ratio in a range of (0.6–1.1). In this range, the bandwidth gets enhanced as r ascends. The ground adjacent to the feeding path helped to achieve responses in X band (8 GHz–12 GHz), and K u band (12 GHz–18 GHz) crossing the range of the whole ultra − wideband (3.1 GHz–10.6 GHz). It responds in some spectrum (18 GHz–22.7 GHz) of the K band (18 GHz–27 GHz) also. • The proposed antenna incorporates a compact and simple geometry which is unique. • It has fractal antenna feature having a compact size of 17.7 × 9.8 × 1.575 mm 3 . • Unveils a −10 dB impedance bandwidth of 19.5 GHz (3.2 GHz–22.7 GHz). • Responds in X, K u , UWB, and a part of K (18–22.7 GHz) bands.
