A novel sum and difference (SD) conical beam-scanning reflector antenna is proposed in
this paper. The reflector surface, illuminated by two omnidirectional horns, is a body of …

The aim of this work is to discuss the synthesis and performance of classical dual-reflector
antennas suited for an omnidirectional coverage. The reflector arrangements are axially …

This communication demonstrates that an open-ended coaxial waveguide can be a good
aperture antenna for generating conical-beam radiation. Design equations are derived to …

The synthesis of classical dual-reflector antennas suited to provide omnidirectional
coverages with arbitrary main-beam direction in the elevation plane is discussed. Both sub …

A novel ultra‐thin radar‐absorbing material (RAM) using metamaterials is presented and the
absorption performance is examined. Due to the high‐impedance property of the …

A hybrid numerical technique is applied for the analysis of circularly symmetric dual reflector
antenna fed by TEM coaxial horn to generate an omnidirectional radiation pattern. By …

Localization using the characteristics of the Radio Frequency (RF) in wireless sensor
networks is attractive because the method does not require additional measuring devices …

This work presents a formulation for shaping the main reflector of a dual-reflector antenna
designed to offer an omnidirectional coverage with an arbitrary radiation pattern in the …

A formulation is presented for shaping dual-reflector antennas designed to offer an
omnidirectional coverage. The shaping procedure is based on geometrical optics (GO) …

This paper considers the use of dual‐reflector antennas for omnidirectional coverage. The
reflectors are axially symmetric surfaces generated by axis‐displaced conic sections. By …
