The RFEH design challenges can be broadly classified into overall radio frequency direct
current (RF-to-DC) power conversion efficiency (PCE), form factor, operational bandwidth …

A novel single-fed, wideband, circularly polarized slot antenna is proposed and fabricated.
Wideband circular polarization is obtained by introducing an antipodal Y-strip to a square …

This letter presents a new broadband circularly polarized (CP) planar monopole antenna
with a simple structure and compact size. Broadband CP operation is achieved by vertically …

A novel ultra-wideband (UWB) circularly polarized (CP) antenna array with sequential phase
feed is proposed in this article. The element implements a multiresonance monopole to …

The design and implementation of a compact monopole antenna with broadband circular
polarization is presented in this letter. The proposed antenna consists of a simple C-shaped …

A broadband circularly‐polarised monopole antenna is proposed. The broadband property
of the antenna is basically achieved not only by the chifre‐shaped monopole radiator, but …

This paper presents a planar metasurface structure for linear to circular polarization (CP)
conversion at the industrial, scientific, and medical bands of 2.4 GHz and 5.8 GHz. The new …

A novel broadband circularly polarized planar slot antenna with microstrip-CPW fed is
proposed in this paper. It consists of a wide rectangular slot and a coplanar waveguide …

A novel broadband circularly polarized antenna is presented in this letter. It consists of a
triangular monopole and a slot etched on the ground plane. By employing a branched …

In this paper, a novel wideband circularly polarized (CP) slot antenna and its array are
presented. The antenna element consists of a C-shaped slot and a 50-microstrip-fed port to …
