This letter proposes a low-profile circularly polarized metasurface antenna with a wide axial-
ratio beamwidth (ARBW). The proposed antenna consists of an array of square metallic …

The complexities that information systems face are quickly growing. Threats and attacks are
framed and executed using new methods that exploit the information contained in networks …

The letter presents a compact circularly polarized (CP) microstrip antenna for airborne
communications. The antenna adopts a square radiation patch with a cross slot to reduce …

A compact circularly polarized wide-beamwidth patch antenna is presented here. The
proposed antenna can be used for blind spot detection in the smart vehicle. Miniaturization …

A double-layer metamaterial absorber is proposed to suppress the mutual coupling within a
circularly polarized (CP) four-element antenna array operating at the Chinese Beidou …

In this communication, a novel excitation technique for the design of a single-point-fed
compact low-profile wide-slot antennas with broadband circular polarization (CP) and wide …

This letter presents the design of a wideband circularly polarized antenna, operating at Ka
band. The proposed antenna comprises a circular microstrip patch antenna that is coupled …

Many Global Positioning System (GPS) services have been recently introduced that extend
over a wide frequency range from 1.16 to 1.61 GHz. For reception, either a wideband or …

A novel broadband circularly polarized (CP) antenna with wide axial ratio (AR) beamwidth is
proposed. It is composed of two curved arms shaped like an inverted “S.” The mechanisms …

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 …
