Analysis and Design Rectangular Microstrip Patch Antenna for LTE Terminals at 2.6 GHz

Abstract

the purpose of this paper is to design a rectangular microstrip antenna in CST MICROWAVE STUDIO (CST MWS). The resonant frequency of the antenna is 2.6 GHz used in LTE radio (operating in band 38 according to 3GPP LTE-TDD). The patch substrate is made of Roger 4350 with dielectric constant (r = 3.48). This rectangular antenna is fed by inset feed lines with particular dimensions which provide good impedance matching. Key performance indicators such as return loss, efficiency, directivity, and antenna side-lobe level in the far-field are obtained from CST MWS software.
