This section presents the structural details of the proposeddual-port antenna design with dimensional information andtopology.We explain the design approaches to achieve a goodisolation between two radiators and the frequency tuningscheme. Different from the previous studies on the dual-portantennas [12], [13], [17] where two PIFAs are merged or asingle element PIFA plate with two feeding ports are used, wecombine two different types of antenna topologies to form adual-port antenna, which is the key to achieve a good port-toportisolation.
