The present paper describes a novel planar antenna based on the fractal structure designed for Ultra-Wide Band (UWB) applications. The antenna exceeds the UWB band by covering the frequency range between 7.36 and 19.57 GHz with S11 < -10 dB (the fractional bandwidth is 90.68 %) which involves four applications, the C-band (4-8 GHz), the X-band (8-12 GHz), the Ku-band (12-18 GHz) and the K-band (18-26.5 GHz). The low-cost Rogers RO4003C substrate is employed to print the proposed antenna in a small dimension of 12 x 16.9 x 0.81 mm3. This antenna is invented from the shape of a flower with three elliptical leaves. The antenna simulated radiation efficiency is greater than 97 % with an omnidirectional radiation pattern in the E-plane and a bidirectional radiation pattern in the H-plane, across the entire bandwidth. The maximum realized gain of the proposed antenna is about 5.25 dBi. Therefore, the obtained results demonstrated that the flower-shaped antenna is a good candidate for practical UWB 5G applications.
