Conventional intercalation cathodes for lithium batteries store charge in redox reactions
associated with the transition metal cations, eg, Mn3+/4+ in LiMn2O4, and this limits the …

Antenna is one of the key components onboard small satellites as its design determines the
performance of all the wireless systems including telemetry, tracking and control, high-speed …

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 …

This communication presents an a cylindrical active frequency selective surface (AFSS)-
based electronically beam-switching antenna, which can operate at two different frequency …

A design approach to miniaturized, dual-resonant microstrip circular sector patch antenna
with tilted circularly polarized (CP) beam is proposed. As mathematically laid down at first …

This paper presents a multibeam dual-circularly polarized (CP) reflectarray for connected
and autonomous vehicles. The developed reflectarray uses one aperture to realize dual …

In this article, the theory, design, and validation of planar array antennas capable of
producing dual-circularly-polarized (dual-CP) dual-beam radiation with a single feeding …

A triband antenna with high gain and low profile is proposed. This antenna is based on the
concept of Fabry-Perot cavity antenna (FPCA) and three resonances are obtained by …

A six-beam switched beam antenna (SBA), whose beam patterns are shaped in the azimuth
plane, is designed and fabricated. A synthesis method, which is based on a four-elements …

A novel planar ultrathin electronically steerable parasitic array radiator (ESPAR) is
presented in this paper. Through theoretical analysis of the electric fields of orthogonally …
