The emerging technology of 3D printing can not only be used for rapid prototyping, but will
also play an important role in space exploration. Additive manufactured parts can be used in …

A metasurface (MS) based on loop elements operating in the near field of a linearly-
polarized microstrip antenna is employed to realize a circularly polarized radiated field. The …

In this paper, we propose an innovative spaceborne isoflux scanning digital phased array
(ISDPA) design with two-stage digital beamforming (DBF) for geostationary satellites. To …

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

This paper investigates a low-Earth orbit (LEO) satellite downlink for high-speed data
communication in interference situations. A choke ring horn type antenna is used as the data …

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 …

In this letter, we propose a novel spaceborne isoflux scanning phased array (ISPA) antenna
at Ka-band for geostationary Earth orbit satellite communications. The ISPA can adaptively …

A spaceborne Earth‐coverage phased array (ECPA) antenna at Ka‐band is proposed for
low‐Earth orbit (LEO) satellite applications, which is based on digital beamforming (DBF) …

This paper introduces a compact, circularly polarized spidron-fractal slot antenna with a
rectangular island. The reflection-coefficient| S11| of the proposed antenna covers the band …

Abstract Space and aerospace exploration have the highest regulations regarding design
and manufacturing processing. As a result, an immense multi-tier manufacturing system has …
