An overview about mutual coupling analysis in antenna arrays is given. The relationships
between array impedance matrix and embedded element patterns, including beam coupling …

Large arrays of radios have been exploited for beamforming and null steering in both radar
and communication applications, but cost and form factor limitations have precluded their …

The very demanding requirements of the SKA-low instrument call for a challenging antenna
design capable of delivering excellent performance in radiation patterns, impedance …

An optimal beamforming strategy is proposed for performing large-field surveys with dual-
polarized phased-array-fed reflector antennas. This strategy uses signal-processing …

We present the design and development of the electronic multi-beam radio astronomy
concept (EMBRACE), a demonstrator that is part of the European contribution towards the …

The system design of a cryogenic 2-13 GHz feed is considered with emphasis on its
application in future wideband radio telescope systems. The feed is based on the so-called …

The radio frequency window of the Square Kilometre Array is planned to cover the
wavelength regime from centimeters up to a few meters. For this range to be optimally …

Phased arrays have a long history in radio astronomy. Large, sparse synthesis arrays have
been in use for decades to capture high-resolution images of deep space objects. More …

The results of a parametric study and design of an ultrawideband dual-polarized array of
differentially-fed tapered slot antenna elements are presented. We examine arrays of bunny …

Two methods for defining the efficiencies and system noise temperature of a receiving
antenna array have recently been developed, one based on the isotropic noise response of …
