A Compact Microstrip-Fed MIMO Antenna For 2.4 GHz Applications

A novel MIMO antenna composed of two symmetrical radiating elements is proposed. The major advantages of the proposed antenna are its dimensional size and low mutual coupling between antenna elements. For a high bandwidth microstrip patch antenna, a dielectric FR4 substrate is designed and compared with previously designed patch antennas. For rectangular patch antennas with microstrip line feed are designed for resonant frequencies. Antennas with radiating elements in presence of shared ground plane is designed with a beveled rectangular metal patch and the T-shaped stubs are presented in the shared ground plane to generate high isolation between the (multiple-input multiple-output) antenna element. The patch array operates at 2.4 GHz for Wi-Fi applications. Results show that the proposed antenna with good radiation patterns, impedance matching, and return loss characteristics are achieved.
