Abstract: This paper presents a circularly polarized antenna for smartphones, positioned at the top bezel of the device. The antenna exhibits a –6 dB impedance bandwidth ranging from 2.36 GHz to 2.76 ...

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 ...
