Multi-beam antennas are critical components in future terrestrial and non-terrestrial wireless
communications networks. The multiple beams produced by these antennas will enable …

This chapter investigates mutual coupling in finite antenna arrays that are conformal to
curved surfaces. It describes a Green's function representation of two quadric surfaces, the …

In order to evaluate the transmission performance of orbital angular momentum (OAM)
beams with a parabolic antenna, this letter investigates the attenuation of OAM beams …

This paper introduces a novel information-theoretic approach for studying the effects of
mutual coupling (MC), between the transmit and receive antennas, on the overall …

Abstract 3D printed X-Ku band single horn antenna and 2× 1 and 2× 2 pyramidal horn array
antennas with novel lightweight and monolithic waveguide feeding networks (WFNs) are …

Dynamic modification of the pattern of a reflector antenna system traditionally requires an
array of feeds. This letter presents an alternative approach in which the scattering from a …

The design of the radiating elements of a S-band planar array for air traffic control
applications is addressed. Toward this end, a novel aperture-stacked patch (ASP) is …

The development of horn antennas is described from their inception in the 1890s to the
present. Our main objective is to describe the advancement of their fundamental features …

A recently developed microwave dual waveguide sensor is applied for the measurement of
gap in concrete-based composites in this paper. The sensor includes two waveguide …

In this study, X-Ku band 3D printed horn antennas coated with copper, chromium and nickel
are designed and fabricated by means of fused deposition modelling (FDM) technique that …
