Superbackscattering Antenna Arrays [PDF]
This article discusses the theory, design and practical implementation of superbackscattering antenna arrays. In analogy with Uzkov’s maximal directivity theorem, it is demonstrated that the maximal backscattering cross-section, normalized to the wavelength squared, of a linear array of N isotropic scatterers whose separation tends to zero is N2(N + 1 ...

This letter proposes a class of sine corrugated cavity resonators (SCCR). The SCCR can present slow‐wave features and provide dual‐mode (TE104 and TE105) wideband responses with reasonable sine period and depth. Based on it, a compact high‐gain bandwidth‐

A Compact Aperture-Sharing Sub-6 GHz/Millimeter-Wave Dual-Band Antenna
In this article, a microwave (MW)/millimeter wave (MMW) aperture-sharing antenna is proposed. The antenna is constructed using two orthogonal columns of grounded vias from a 3.5 GHz slot-loaded half-mode substrate-integrated waveguide (HMSIW) antenna ...

Theoretical analysis and comparison of OAM waves generated by three kinds of antenna array
Antenna array is one of the methods which can generate Orbital Angular Momentum (OAM) waves. However, OAM waves generated by different antenna arrays have different characteristics of Electric-field (E-field) components’ distribution and radiation ...

Design of UAVs-Based 3D Antenna Arrays for a Maximum Performance in Terms of Directivity and SLL
This paper presents a design of UAVs-based 3D antenna arrays for a maximum performance in terms of directivity and side lobe level (SLL). This paper illustrates how to model the UAVs formation flight using 3D nonuniform antenna arrays.
