A low-profile wideband circularly polarized (CP) crossed-dipole antenna that has both wide
axial-ratio beamwidth (ARBW) and half-power beamwidth (HPBW) is presented in this …

This communication presents a single-feed ultra-wideband circularly polarized (CP) antenna
with high front-to-back ratio (FBR). The antenna is composed of two orthogonally placed …

A low-profile dual-band dual-mode and dual-polarized (DBDMDP) antenna based on
artificial magnetic conductor (AMC) is presented in this letter. One reference antenna made …

This literature review focusses on probe-fed unidirectional crossed dipole antennas (CDAs)
for multiband and broadband circular polarization (CP). It describes the hierarchical …

In this article, a low-profile high-efficiency dual-band 0.915/2.45 GHz circularly polarized
(CP) antenna and its array are designed for radio frequency identification (RFID) reader …

A cavity-backed triangular-complimentary-split-ring-slot (TCSRS) antenna based on
substrate integrated waveguide (SIW) is proposed in this communication. Proposed antenna …

In this letter, a microstrip-fed simple square slot antenna is proposed for triple-wideband
triple-sense circularly polarized radiation. It consists of an L-shaped radiator and a frame …

A dual-wideband circularly polarized (CP) antenna was proposed based on the strategy of
combining multimode resonances. The primary radiators were two barbed-shape dipoles …

This paper presents a new approach to design dual‐band antenna with dual‐sense
circularly polarized (CP) operation. A principle for CP radiation is the use of two orthogonal …

In this article, an ultrawide band circularly polarized crossed dipole antenna is proposed for
near-field synthetic aperture radar imaging. The presented antenna comprises two …
