Abstract：

A　compact　directional　MIMO　antenna　operating　in　2.4　and　5　GHz　wireless　local　area　network　(WLAN)　bands　is　presented.　The　compactness　of　the　proposed　multiple-input　multipleoutput　(MIMO)　antenna　can　be　attained　through　using　miniaturized　antenna　elements　and　meanwhile　employing　an　extremely　narrow　edge-to-edge　inter-element　space　(3　mm).　Two　novel　miniaturized　planar　inverted-F　antenna　(PIFA)　elements　which　share　a　common　ground　are　designed,　and　each　element　has　a　dimension　of　31　mm　×　17　mm　and　a　profile　of　4.2　mm.　By　etching　three　slots　on　the　ground,　the　port　isolation　can　be　significantly　enhanced,　which　can　even　reach　a　maximum　of　54　dB　at　2.45　GHz.　A　desirable　directional　radiation　pattern　is　obtained,　and　the　calculated　envelope　correlation　coefficient　is　better　than　0.01.　©　2017,　Electromagnetics　Academy.　All　rights　reserved.
