A novel ultra-wideband (UWB) circularly polarized (CP) antenna array with sequential phase feed is proposed in this article. The element implements a multiresonance monopole to achieve UWB CP radiation. To investigate the CP operating mechanism, characteristic mode analysis is used to provide differ...
