Broadcasting, radar, sonar and space telecommunication systems use phased arrays to
produce directed signals to be transmitted at the desired angle. This system requires a large …

Inspired by the biological evolution and the natural selection, evolutionary algorithms have
already shown their success in obtaining the solutions for many complex optimisation …

Sonar, radar and communication systems solely depend on antenna arrays for signal
attainment. These arrays are capable of producing directional signals which can be steered …

Planar antenna arrays are considered as the one of the important parts in the applications
like broadcasting, sonar and radar communication. In order to produce the directed beam of …

In the present paper three evolutionary algorithms are compared and discussed for
synthesizing a linear array of dipole antenna of halfwavelength oriented horizontally. All the …

This study presents a novel method for reducing return loss and achieving lower side lobe
levels in small planar antenna arrays (PAAs). Quantum particle swarm optimisation (QPSO) …

The reliability of phased array antenna can be improved with the self-repairing technology,
and the existing self-repair method based on the TR module reconfiguration has problems …

In this paper, multi-objective particle swarm optimization (MOPSO) and continuous excitation
distribution in the range of 0 to 2 are used for correction of the failed element in 5× 5 planar …

A ground-based synthetic aperture radar system (GB-SAR) comprising of 12 horn antennas
in its transmitter section and 12 Vivaldi antennas in its receiver section is used for the …

A new technique for the restoration of the field pattern in a linear array constructed using
parallel dipole antennas is carried out by altering the spacing between the array elements …
