Abstract

This paper presents a monopole antenna design using Sierpinski triangle fractal geometry with an improved frequency response. The antenna response has been optimized using the genetic algorithmic approach. Triangular slots have been incorporated in the ground plane section, which has an effect on antenna return loss. A triangular shaped patch with Sierpinski triangle geometry has been placed above Beryllia (99.5%) substrate having an electrical permittivity of 6.5. The resonant frequency peak of proposed antenna is exactly at 2.45 GHz with an impedance bandwidth of 650 MHz. The antenna finds its application in 2.4 GHz (2.41–2.48 GHz) WLAN band with a maximum realized gain of 3.16 dBi at the resonating frequency.
