This paper describes the modelling and analysis of a new smart antenna concept. The paper outlines the rational for the development of a dynamically reconfigurable smart antenna system without greatly increasing the complexity of the system. The subject smart antenna system is developed to offer good coverage and capacity using multiple beams throughout a cell sector and to be able to reconfigure...
We have designed and built the first commercially available all-analog adaptive beamforming integrated circuit utilizing a dual microphone array. Beamforming performs spatial filtering by exploiting time-of-arrival differences between microphones. Our analog implementation has the advantage of using very little power which is important in portable, battery-powered devices. Rather than optimize parameters...
A novel design solution of a dual-linearly-polarised Ku-band low-profile radiating element for low elevation angle coverage (down to 10° above horizon) is presented. Such an element is suitable for full-duplex Satellite Communications On-The-Move (SCOTM) hybrid scanned phased array antenna applications. Standard-designed radiating elements for array applications with low profile physical structure...
A novel design solution for a low-profile full-duplex satellite-on-the-move communications hybrid scanned phased array antenna for low elevation angle coverage (down to 10??) is described. The antenna is operated at Ku-Band. The unique louvered array element geometry in combination with a spatial filter/ ??ray bending?? lens facilitates the shaping of the element pattern to increase gain at low elevation...
