Design of compact fractal patch antenna for X/Ku/K‐band applications

Abstract

This 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 8:10 Â 8:10 mm 2 . 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.

A Hybrid Koch Embedded Sierpinski Fractal Antenna for Uwb & 5g Applications

“…It incorporates a second-order Koch Snowflake fractal pattern etched at the center of the Sierpinski Arrowhead fractal radiator. The design methodology covers the setup of the antenna, the integration of the fractal into the radiator, and the fundamental operational principles of a standard antenna layout [14]. The conventional method of representing the dimensions of the radiator width and length is denoted as Wr and Lr.…”
