Dual Band MIMO Antenna Composed of Two Low Profile Unbalanced Fed Inverted L Antennas for Wireless Communications
The dual band antennas have been investigated with the development of wireless communication systems in recent years. Most of these dual or multiple band antennas have an omnidirectional radiation pattern. A low profile dual-band Multiple-Input-Multiple-Output (MIMO) antenna system is proposed. The proposed MIMO antenna consists of two low profiles unbalanced fed inverted L antennas with parasitic elements to resonate at 2.45 GHz and 5 GHz. The structure is uncomplicated by locating two ultra low profile inverted L antennas on the finite conducting plane. The proposed MIMO antenna is numerically and experimentally analyzed.
