Compact Triangular Microstrip Antenna With Fractal Ground
— In this paper, the design of a new compacted triangular microstrip antenna by the use of fractal ground plane is presented. This antenna is suitable for WLAN applications at operating frequency of 2.4 GHz. At first, the design process begins by a triangular patch antenna fed by a microstrip line supported by an FR4 substrate with dielectric constant of 4.7 and a thickness of 1.6 mm. The backward side of the substrate is covered by a total ground plane. The miniaturization strategy is performed by applying a third order of the Sierpinski carpet to the ground which leads to 27.2% of size reduction. The proposed antenna is simulated by CST Microwave Studio Software. Results are analyzed in terms of return loss, VSWR, bandwidth and radiation patterns.
