The　pattern　reconfigurable　antenna　provides　a　new　implementation　scheme　for　expanding　application　in　modern　wireless　communications.　In　this　paper,　a　pattern-reversal　wideband　microstrip　antenna　is　proposed.　This　antenna　is　composed　of　a　radiation　patch　with　attached　rectangular　metal　rings　connected　by　a　microstrip　line　on　the　upper　layer　and　a　four-defects　ground　plane　connecting　two　PINdiodes-loaded　L-shaped　stubs　on　the　bottom　layer.　In　view　of　the　Yagi-antenna　feature　of　metal　rings　and　L-shaped　stubs,　the　ON-OFF　of　diodes　controls　directly　the　radiation　direction　of　antenna.　Under　the　joint　action　of　multiple　resonances　of　rings,　slots　and　stubs,　the　bandwidth　of　antenna　is　surged　so　as　to　develop　evident　wideband　radiation.　Finally,　the　measured　impedance　bandwidth　of-10　dB　is　about　20.1%　from　4.54　to　5.55　GHz.　The　average　gain　of　the　antenna　with　the　size　of　$0.75　λ0　×　0.75　λ0　reaches　4.92　dBi.　With　the　diodes　dependence,　the　pattern　can　really　deflect　in　opposite　direction.　The　designed　antenna　has　much　advantages,　such　as　low　cost,　wider　band,　compact　and　simple　structure　along　with　explicit　application　scenarios.　©　2020　IEEE.
