In this work, a four element multiple‐input‐multiple‐output (MIMO) antenna system with half circle shape printed monopole antennas is presented. The antenna elements are designed on an FR4 substrate with dielectric constant 4.3 and dimensions of 110 × 60 × 0.8 mm 3 . These antennas are covering part of 4G and WLAN bands with maximum measured gain and efficiency of 3.12 dB and 81.5%, respectively, along with a −10 dB bandwidth of 230 MHz. The coupling between adjacent ports is at least −11 dB without using any technique for isolation enhancement. The MIMO antenna system has good pattern isolation such that the correlation coefficient is calculated using the measured three‐dimensional (3D) far field radiation pattern with a maximum value of 0.3 at 2.4 GHz. The proposed design can be used in handheld terminals. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2990–2992, 2016
