In addition to Internet service, new commercial broadband low-Earth-orbiting (LEO) satellites
could provide a positioning, navigation, and timing (PNT) service far more robust to …

Abstract Gaseous Plasma Antennas (GPAs) are devices that exploit weakly or fully ionized
gases to transmit and receive electromagnetic (EM) waves. GPAs can offer several …

The frequency-hopping communication system has been widely used in anti-jamming
communication due to its anti-interception and anti-jamming performance. With the …

This paper presents the design of a novel multipath mitigating ground plane for global
navigation satellite system (GNSS) antennas. First, the concept of a compact low multipath …

A novel low-profile grooved-dielectric choke ring with dual-band surface impedance
resonance is proposed and experimentally demonstrated. The proposed structure is …

This letter presents a method of cross-polarization suppression at low-elevation angle for a
compact circularly polarized (CP) microstrip antenna. The compact CP antenna adopts a …

This letter presents a miniaturized geodetic choke ring antenna for high-precision Global
Navigation Satellite System applications. The antenna consists of crossed dipoles that are …

The BDS multipath delay error is highly related to the surrounding monitoring environment,
which cannot be eliminated or mitigated by applying the double difference observation …

In this article, a novel technique for the miniaturization of corrugated structures is presented,
and multifolded corrugations (MFCs) are introduced. The miniaturization is achieved by …

A low-cost light-weight 3D-printed copper coated choke ring is presented and
experimentally demonstrated to have similar performance to a fully metallic choke ring. The …
