Abstract

A novel microstrip antenna with filtering characteristics is proposed for 5G Global wireless communication applications. The proposed filtenna consists of three parts: the monopole radiating patch antenna; the Stepped Impedance Resonator (SIR) filter; and the feeding microstrip line. The structure design is achieved on one‐sided glass epoxy FR‐4 substrate with dielectric constant εr = 4.4 and thickness h = 1.6 mm. The proposed microstrip filtering antenna is a compact single layer filtering microstrip antenna with characteristics of low profile and a wide‐band impedance bandwidth of about 3.5 GHz which makes the design suitable for broad casting data for long distance communications. The simulation results are generated by using the Computer Simulation Technology (CST) software package. The S11 parameters obtained when single SIR filter is used are not in the desired operating frequency but the S11 parameters obtained when two SIR filters are used
