Abstract
A multiple-input-multiple-output (MIMO) antenna is proposed for ultra-wideband (UWB) applications with high isolation capability. The proposed MIMO structure consists of two simple square monopole antennas with slotted ground plane structure with S11 bandwidth of 2.2 to 10.8 GHz and isolation level better than -30 dB. U-shaped and L-shaped slots are adopted to realize a notched band within 3.3-3.8 GHz relating to WiMAX frequency band. With the aim of enhancing the isolation between the monopole antennas, two parasitic structures are wisely embedded between the monopole antennas on backside of the substrate. The MIMO antenna prototype with a compact size of 25×38 mm2 is fabricated and measured. Based on the simulation and experimental results, the proposed MIMO antenna well-performs in ultra-wideband (UWB) band-notched MIMO application.
