Abstract
SummaryThis paper presents a fractal‐based compact new monopole antenna for wideband applications. The miniaturization has been achieved by incorporating Minkowski and Koch‐snowflake fractals. The proposed antenna design is etched on top of Rogers RT/5880 dielectric material with a dimension of mm2. The antenna is designed, analyzed, fabricated, and tested in the laboratory. The proposed geometry operates over a 8.62–22.40 GHz with fractional bandwidth (FBW) of 88.84% and VSWR is less than 2. The proposed monopole antenna exhibits nearly omnidirectional radiation patterns over the entire resonating band with a gain of 1–2.91 dBi and a radiation efficiency of more than 60.5%. Also, the measured results of the prototype make an excellent agreement with the simulated counterpart. Further, the antenna gives good time‐domain characteristics. Therefore, the proposed miniaturized antenna can be used in X/Ku/K‐band applications.
