Abstract
ABSTRACTThis article presents a wideband multiple‐input‐multiple‐output (MIMO) antenna assembly for combined WiFi/WLAN/LTE applications. The antenna consists of two radiating triangular patches placed in a mutually orthogonal configuration. Two T‐slots and a rectangular slot were cut on the ground plane to improve the return loss and isolation. The surface footprint of the antenna is 30 × 30 mm2. The antenna impedance bandwidth is 101.7% between 2280 and 7000 MHz; the reflection coefficient and mutual coupling are better than −10 dB, and −14 dB, respectively. The MIMO antenna performance characteristics are given in terms of the scattering parameters, envelope correlation coefficient, total active reflection coefficient, capacity loss, channel capacity, VSWR, antenna gain and radiation patterns. Analysis of these characteristics indicates that the design is appropriate for the target WiFi/WLAN/LTE terminal applications. © 2015 Wiley Periodicals, Inc.
