Abstract :
A novel wide-band multiple-input multiple-output (MIMO) antenna system with high port isolation is proposed. The antenna system consists of three equally spaced antennas mounted on a hollowed triangle ground. The antenna system was designed to operate at frequency bands between 2 and 6 GHz. Each antenna mainly comprises of a shorted, inverted wide L (shorted iWL, a unique feeding design), sitting on a vertical ground attached to the horizontal plane of triangular shape. From simulation and experimental results, the proposed MIMO system exhibited superb characteristics at 2.4, 3.5 and 5 GHz bands, with significant isolation performance due to the design of the practical and novel ground structure.
