Abstract

This paper presents a novel dual-feed Planar Inverted-F Antenna (PIFA) for MIMO radio communication systems at 2.45 GHz. This antenna contains only one radiating plate with two matched and isolated ports. To reduce the mutual coupling and to achieve a good isolation, ground plane under the top radiating plate is etched. The calculated envelope cross-correlation is less than 0.02 and the ratio of the mean effective gain between the two ports is close to unity. It is shown that a single PIFA antenna can be used instead of two antennas for diversity gain which is an excellent solution for saving the space and cost. Simulated and measured results are provided to verify the conclusion.
