Abstract

This paper presents the design of a circularly polarized slot antenna on a flexible substrate for ultra-wideband (UWB) high-band applications, as well as the behavior of the antenna near a human body. We used two slots that were crossed perpendicularly to obtain a circularly polarized wave. We realized wideband impedance matching to optimize the lengths and widths of the antenna slots and substrate. The impedance bandwidth of proposed antenna is 5.60 GHz from 7.11 to 12.71 GHz, and the antenna size is 16 mm × 16.3 mm × 0.254 mm.
