This article presents a systematic procedure to shape the body of an electrically large object
in order to achieve a desired radiation/scattering pattern. In particular, the object surface is …

In the design of horn array antennas, usually there is a challenge with the grating lobe
problem and consequently quite low aperture efficiency. A new configuration for horn array …

This work uses the active and parasitic components in a linear antenna array composed of
parallel dipoles to synthesize a cosecant squared pattern using the Quantum Particle Swarm …

ABSTRACT A new technique for broadband shaped beam reflector antennas synthesis is
presented. The surface of the shaped reflector is represented by a set of orthogonal Jacobi …

Generation of the plane-of-symmetry vertical profile for a double-curved reflector antenna with
cosec² &a Page 1 Generation of the plane-of-symmetry vertical profile for a …

In this paper, a reflector antenna with a cosecant-squared and wide beam pattern is
presented. The cosecant-squared antennas with different structures were reported to …

The feasibility of deploying reflectarray antennas on synchronous satellites with the aim of
achieving isoflux beam for optimum earth coverage is investigated. Due to the difference in …

Through this paper, we propose quad-band electromagnetic wave metamaterial absorber
structure consist of square rings resonators arranged in two-dimensional periodic array with …

This paper presents an efficient method to redesign a horn-fed, double-curvature reflector
antenna. It helps reconstruct or repair the reflector according to a correct reference or …

In this paper, a multi band metamaterial absorber at (C, X, Ku, and K Band) is presented in
microwave frequency band. The unit cell geometry comprises of two split ring resonators …
