m-Shaped SSPPs Structure to Low Profile Vertically Polarized Antenna With High Gain to Be Conformal With Vehicle Shell

An m-shapedspoof surface plasmon polaritons (SSPPs) structure as well as its application into end fire antenna with vertical polarization, low profile and compact size are proposed to be conformal with vehicle shell. Beside the primary odd SSPPs mode in the center, extra even mode at the top horizontal arms and odd mode at the end of the arms are introduced through folded arms. Consequently, the e...
