Abstract: In this letter, an omnidirectional circularly polarized antenna (OCPA) that operates across Ku band and K band is proposed. A metasurface whose phase difference decreases monotonically with ...

Abstract: A horizontally polarized omnidirectional (HPO) antenna with ultralow cross-polarization level (XPL) is presented for a 2.4 GHz wireless local area network (WLAN) application. The proposed ...
