Abstract

A Dual-band microstrip antenna based on split-ring elements is introduced for GSM/DCS (900/1800MHz) applications. The proposed split-ring antenna (SRA) has novel design and provides 2.3% and 3.8% impedance bandwidth performance at the respective bands without a need for additional matching networks. Also, the antenna exhibits uniform radiation patterns at each frequency band. Analysis and design of the proposed microstrip antenna are carried out by means of full-wave simulators based on the finite-element method, namely the in-house Finite Element Microstrip Antenna Simulator (FEMAS) and the commercially available High Frequency Structure Simulator (HFSS). Return-loss characteristics of the antenna using the simulators are in good agreement
