Hepta-band DRA loaded Minkowski Fractal Slot Antenna

Abstract

A hepta-band dielectric loaded Minkowski Fractal Slot Antenna is presented in this article. Fractal geometry is utilized to generate multiple frequency bands conforming to various wireless standards. The idea behind placement of the dielectric resonator is to increase the impedance bandwidth at the upper frequency band. The proposed antenna exhibits a hepta-band performance over the frequency range of (900 MHz-7.5 GHz) with a gain variation of 1.1-3.1 dBi.
