This paper presents a compact low-cost circularly polarized UWB antenna covering both UWB channels 5 and 9. The antenna is based on a capacitively fed patch element excited through a quadrature hybrid coupler. The reported field tests demonstrate that the circular polarization provided by the proposed antenna allows the anchor-tag communication to be improved and made independent of the relative orientation between the two devices.

Abstract
This paper presents a compact low-cost circularly polarized UWB antenna covering both UWB channels 5 and 9. The antenna is based on a capacitively fed patch element excited through a quadrature hybrid coupler. The reported field tests demonstrate that the circular polarization provided by the proposed antenna allows the anchor-tag communication to be improved and made independent of the relative orientation between the two devices.| File | Dimensione | Formato | |
