AB An offset quad-element, two-port, high-gain, and multiband multiple-input multiple-output (MIMO)planar antenna based on a log-periodic dipole array (LPDA) for Ku/K-band wireless communicationsis proposed, in this paper. A single element antenna has been designed starting from Carrel’s theoryand then optimized with a 50-Ω microstrip feed-line with two orthogonal branches that results mainlyin a broadside radiation pattern and improves diversity parameters. For experimental confirmation,the designed structure is printed on an RT-5880 substrate with a thickness of 1.57 mm. The totalsubstrate dimensions of the MIMO antenna are 55 × 45 mm2.According to the measured results, thedesigned structure is capable of working at 1.3% (12.82–12.98 GHz), 3.1% (13.54–13.96 GHz), 2.3%(14.81–15.15 GHz), 4.5% (17.7–18.52 GHz), and 4.6% (21.1–22.1 GHz) frequency bands. Additionally,the proposed MIMO antenna attains a peak gain of 4.2–10.7 dBi with maximum element isolation of23.5 dB, without the use of any decoupling structure. Furthermore, the analysis of MIMO performancemetrics such as the envelope correlation coefficient (ECC) and mean effective gain (MEG) validatesgood characteristics, and field correlation performance over the operating band. The proposed designis an appropriate option for multiband MIMO applications for various wireless systems in Ku/K-bands.
