In this article, a shared-aperture design of the cellular antenna and satellite communication
antenna with circularly polarized (CP) in the S-band for metal-bezel smartphones is …

A high-gain reflectionless circularly polarized (CP) filtering antenna is proposed. A
quadrature hybrid coupler (QHC) is cascaded with two identical, mutually isolated, and …

This letter presents a stacked patch antenna for circularly polarized (CP) filtering without any
additional filtering structures. The lower patches consist of a square patch with truncated …

A corporate feed sequentially rotated 2× 2 circularly polarized fractal antenna array is
investigated in this work. Four number of compact circular fractal antenna elements are …

This article proposes a full-metal omnidirectional series-fed filtenna array. The antenna is
primarily composed of an outer metal shell, a built-in metal post and three pairs of open …

A single-layer differentially fed circularly polarized (CP) filtenna with common-mode
rejection is presented in this letter. It is composed of a circular patch, a circular substrate …

This letter proposes a circularly polarized (CP) filtering antenna with a wide axial ratio (AR)
bandwidth generated through a multilayer structural design. The proposed antenna provides …

This letter presents a simple structure wideband circularly polarized (CP) dipole antenna
with bandpass-type filtering radiation response. It consists of a cross-dipole radiator with the …

The circular-polarized (CP) filtering antenna design based on the radiation-null-introducing
technique emphasizes introducing specific filtering structures on the radiator or feeding …

A planar differentially-fed circularly-polarized filtering antenna with enhanced axial ratio
(AR) bandwidth is proposed. The proposed design consists of a square substrate integrated …
