Design and development of compact fractal antennas for multiband wireless applications

Abstract

Currently researchers have given much importance for designing a compact multiband and low cost microstrip antenna to meet the miniaturization requirements of portable handheld communication equipment The commonly used antennas are microstrip slot and coplanar waveguide antennas Antennas capable of operating at dual band multiband cost effective and good bandwidth are needed for upcoming wireless standards The physical size weight and multiband are the major issues in wireless application This initiated antenna researchers to develop an assortment of antennas to fulfill the requirements The inherent feature of patch antenna is to resonate for single narrowband An antenna competent of screening assortment of frequency bands is desirable for present wireless applications Fractal geometry is a solution which can solve the needs of wireless applications Fractal geometry is a concept in mathematics through which miniaturization multiband characteristics and bandwidth are achieved to complete a range of wireless applications with improved return loss Therefore miniaturization has become the most important objective of a Radio Frequency designer It offers mobility and affordability in wireless mobile devices
