A wideband dual-polarized planar antenna is designed and analyzed by using the theory of characteristic modes (TCM). The\neigenvalue, eigencurrent, characteristic pattern, and modal weighting coefficient are analyzed to bring physical insight to this kind\nof antenna.Theresults demonstrate that there are two modes resonant in the operating band for each polarization, which have been\ncombined to form a wider frequency band. A bandwidth of 60.2% (1.72ââ?¬â??3.2GHz) for VSWR < 1.5 with high isolation of 32 dB is\nachieved simultaneously. The size of the radiator structure is 0.33
