Abstract
The aim of this work is to design and characterize a compact 5G antenna with an appreciable bandwidth. In the suggested antenna, two fractal curves are applied onto the conducting patch that helped to achieve the targeted operational characteristics. The whole patch is printed on the chosen FR4 material. The modified rectangular patch is placed on the top side, whereas a partial ground is placed on the bottom side. The antenna size observed is 45 mm2. The overall adjustments of the specific design parameters are carried out for better S11 characteristics at the fundamental resonance. The operational band stretches from 25.99 GHz to 27.72 GHz with a fractional bandwidth of 6.4%. The designed antenna showed resonance at 26.75 GHz with S11 value -21.00 dB. The proposed antenna possesses good S11 characteristics, appreciable gain, and significant bandwidth at the operational frequency band. Moreover, the influence of variations in the antenna geometry has also been demonstrated for deep understanding.
