Abstract Many modern microwave systems, for example, in the field of satellite communications, remote sensing for Earth observation or radio astronomy, employ reflector antennas with beam‐shaping capabilities. A generalised description of multi‐c

K a -band reflector antennas are of interest for satellite-based synthetic aperture radar (SAR) Earth observation missions. In practice, the antenna performance may decrease due to mutual coupling within the feed and with the reflector. Here, the imp

Array-fed reflector antennas are being considered for various synthetic aperture radar (SAR) satellites. Mutual coupling between the array elements, as well as with the reflector, impact the antenna performance significantly. The impact of this coupl

In this paper, we propose a new beamforming scheme for pulse-based signals, particularly, for ultra wideband pulses, by employing a random array geometry and an orientation matching of the arrays. Unlike conventional directional beamforming, the intr

The article explains the orientational beamforming concept from a perspective of spread-spectrum communication not in the frequency domain but in the spatial domain. In the orientational beamforming concept, radiated signal energy is spread over a ce
