This letter studies the potential capacity advantages of introducing a dual polarization per
beam paradigm instead of the conventional single polarization per beam in mobile satellite …

A compact axial-mode helical antenna (AMHA) is presented based on spoof surface
plasmon polaritons (SSPPs). The proposed antenna consists of an SSPP waveguide, a …

We have proved in theory and simulation that the circularly polarized (CP) radiation from a
resonant quadrifilar helix antenna (QHA) is independent of the phase between two …

This article presents a polarization reconfigurable dual integrated quadrifilar helix antenna
array that is embedded within a cylindrical-shaped mesh of dielectric material. The entire …

A novel single helix antenna with wideband and dual circularly polarized (CP)
characteristics is proposed in this communication. The left-handed CP (LHCP) and right …

For the terrestrial infrastructure, the multiple-input multiple-output (MIMO) architecture is a
key technology that has brought the wireless gigabit vision closer to reality. Satellite …

The accurate design of earth–space systems requires a comprehensive understanding of
the various propagation media and phenomena that differ depending on frequencies and …

Research on mobile satellite and high-altitude platform (HAP) systems (MSHSs) has
recently proliferated because of the allocation of additional spectrum, the intense …

In this letter, a compact circularly polarized (CP) multimode antenna for global navigation
satellite system reflectometry (GNSS-R) is presented. The design comprises two quadrifilar …

In this letter, we propose a novel feed network for circular polarization (CP) diversity
antennas to enhance communications performances. The previous CP diversity systems …
