The global navigation satellite system is a high-precision radio navigation system based on
artificial satellites. Among the factors affecting the positioning accuracy of the navigation …

In the paper, a wideband GNSS antenna with wide-angle circular polarization and anti-
multipath performance is proposed. By using the coupled feeding formed by arc-T-shaped …

An anti‐multipath antenna is an antenna that can effectively suppress multipath signals from
the source of signal reception. There are many problems in the traditional choke design …

Multipath interference in cities has always been one of the main problems leading to
abnormal positioning results of a global navigation satellite system. Vector tracking is …

This communication introduces the concept of coupled annular aperture antenna array
(CAAAA) that enhances CubeSat earth coverage with dual circularly polarized (CP) isoflux …

This letter presents the compact hybrid choke rings for the dual-band circularly polarized
global positioning system (GPS) antenna, in order to suppress the surface wave propagation …

In this work, we present the design and modeling of a new type of choke horn antenna. It
incorporates a rectangular waveguide and a rectangular choke acting as a parasitic …

Global navigation satellite systems (GNSSs) are at the basis of many location services.
However, in harsh environments such as urban canyons, the performance can be highly …

In order to inhibit surface wave propagation and lower back lobes level the dual-band
circularly polarized high precision GPS antenna is designed. The two radiation patches …

This paper introduces the new design of a choke loaded horn antenna, at 89.75 GHz for
metrology of the large paneled reflector antenna using the Fresnel field based radio …
