Study on isolation improvement between closely‐packed patch antenna arrays based on fractal metamaterial electromagnetic bandgap structures

Comparison between Metamaterial based circular patch antenna and microstrippatchAntenna

The Metamaterial based antenna is designed for some improvement in the performance of directivity gain, return loss and size of circuit area. A patch antenna has been designed and fabricated to operate between 1Ghz.-3Ghz. The aim of the project is to design and fabricate metamaterial antenna and study the effect of antenna dimensions Length (L), Width (W) and substrate parameters relative Diele...

Investigation on Microstrip Patch Fractal Antenna

Abstract A new design of Microsrtip patch fractal antenna for 2.5 GHz is proposed which possess an excellent size reduction possibility with good radiation performance for wireless applications like Wireless Local Area Network (WLAN). The design and simulation results of microstrip patch fractal antenna using Ansoft HFSS is presented which has S11 < -10 dB (VSWR<2). The antenna is designed base...

Analysis Of The Patch Antenna Based On The Sierpinski Fractal

There has been an ever growing demand for antenna designs that possesses compact size, low profile and multiband features. Recently the possibility of developing antenna designs that exploit in some way the properties of fractals to achieve these goals, at least in part, has attracted a lot of attention. Fractal antennas have useful applications in cellular telephone and microwave communication...

Micromachined tunable filter using fractal electromagnetic bandgap (EBG) structures

A tunable bandstop filter using fractal electromagnetic bandgap (EBG) structure is designed, simulated and fabricated. The uniform fractal EBG U-FEBG) structure is realized by replacing the etched rectangular holes with a Minkowski loop generator. A new technique of doubly tapered ractal EBG (DT-FEBG) structure is designed by non-uniform Kaiser distribution on the fractal structures. The Kaiser...
