This communication presents a reconfigurable antenna capable of independently
reconfiguring the operating frequency, radiation pattern and polarization. A switched grid of …

The beam pattern of an antenna array is one of the most important characteristics of
classical phased arrays and of more modern smart antenna, digital beamforming and …

The antenna array manifold is central to high-resolution direction finding. The analytic
manifold is defined here as the mathematical model of the array response calculated by …

The limitations of current mutual coupling compensation methods in antenna arrays are
thoroughly reviewed. The theory of mutual coupling compensation is unified in such a way …

We present a thorough examination of two-element antenna arrays that mimic the sense of
directional hearing of the parasitoid fly Ormia Ochracea and examine the design tradeoffs of …

In this paper, a quasi-tapered wideband antenna using a circular-shaped with an inverted-
omega ground structure is presented. A tapered antenna is usually developed based on …

A general method to obtain a matrix which allows the compensation of mutual coupling
effects in transmitting arrays for the total field in all directions is introduced. This method is …

In this communication, the characteristic mode analysis (CMA) is applied to the analysis of
mutual coupling in a receive-mode antenna array with geometric symmetry. Because CMA …

Amplitude and phase errors among multi-channels in digital array radar will seriously
deteriorate the performance of digital beam-forming (DBF) and high resolution direction …

In this paper we present a novel way of jointly estimating the coupling matrix of closely
spaced receive antennas as well as the spatial channel of compact MIMO systems. Unlike …
