Wideband planar phased arrays for the square kilometre array

2010 IEEE International Symposium on Phased Array Systems and Technology, 2010
The Square Kilometre Array development demands a radio telescope with a high sensitivity, dual polarization and wide field of view over a broad bandwidth to meet the scientific goals. For the mid-frequencies of the SKA (nominally 400MHz to 1.4GHz) observation is preferred using wideband phased array to reduce the survey time over the sky.

Selection of phased array configuration

1974 Antennas and Propagation Society International Symposium, 1974
A major decision in the design of phased array antennas is the selection of array configuration. Once the coverage sector, net antenna gain, effective radiated power (ERP) and other system requirements are established, the effects of (1) subdividing the coverage sector, i. e.

Phased array processing for spike discrimination

Neurocomputing, 2005
We present a novel approach for the detection, discrimination, and identification of superimposed neuronal action potentials from multineuronal, multichannel extracellular nerve recordings with low signal-to-noise ratios. The approach uses phased-array processing techniques to identify the spikes from different neurons on the basis of their unique ...

Protein Arrays III: Reverse-Phase Protein Arrays

2017
The reverse-phase protein array (RPPA) is to use highly specific antibodies to interrogate pan or posttranslationally modified protein targets, such as phosphorylated proteins, particularly the proteins involved in cell signaling pathways. In this protocol we will cover the preparation of cell (or tissue) lysates, sample printing, antibody validation ...

RF Phase Shifters for Phased Arrays

2011
Phase shifters are essential components in a phased array for adjusting the phase of each antenna path and steering the beam. There are various types of conventional RF phase shifters, and they are analyzed in detail in this chapter.

Quantities of phase shifters in phased arrays

2008 IEEE Antennas and Propagation Society International Symposium, 2008
The one-element/one-phase shifter phased array does not represent the generalized phased array configuration. The generalized phased array consists of radiating elements, a subarray forming network (SFN), and variable phase shifters. The SFN is, in theory, a lossless network containing neither ohmic nor coupling losses.

Phased array BIT

International Symposium on Antennas and Propagation Society, Merging Technologies for the 90's, 1990
It has been shown by H. Shnitkin (1985) that a 1-D electronically phased array can be aligned to a direction determined by the propagation constant in an ancillary, lightly coupled traveling-wave waveguide feed provided for that purpose. This linear array phase alignment method is extended to a general 2-D phased array alignment and failure isolation ...

Optical Phased Array

IETE Journal of Research, 1999
This paper presents the case of an optical phased array in analogy with its counterpart in the microwave frequency region. It consists of a planar aperture array formed by the discrete illuminated core ends of a number of monomode optical fibres placed adjacent to each other in several rows.
