A Novel Triband E-Shaped Printed Monopole Antenna for MIMO Application

A novel multiband E-shaped printed monopole antenna for multiple-input-multiple-output (MIMO) system is presented. The proposed E-shaped monopole antenna can create a single resonance within the WLAN range. Placement of two slots within the E-shaped monopole antenna creates two extra resonances whose center frequencies can be adjusted by the E-shaped monopole and the slots parameters. The antenna parameters for WLAN application, covering 2.4, 5.4, and 5.8 GHz, are given. Various configurations of array of this E-shaped monopole antenna for MIMO application are also studied. It is shown that good MIMO performance can be achieved even for small element spacing. Simulation and measurement results are compared and discussed.
