A conducting pad is positioned in each gap and is connected via a switch to the ground plane. A microstrip feed line including a short stub is positioned on the opposite side of the substrate and electromagnetically coupled to the slot. The polarization of the antenna is reconfigured by a selection of an on or off state of each of said switches.application/pdfen-USPatenthttp://pimg-fpiw.uspto.gov/fdd/09/736/083/0.pdf12481025343/769H01Q19/005H01Q21/2458373609
