Abstract Central Force Optimization (CFO) is a new deterministic multi-dimensional search
metaheuristic based on the metaphor of gravitational kinematics. It models" probes" that" fly" …

Linear and circular arrays are optimized using the particle swarm optimization (PSO)
method. Also, arrays of isotropic and cylindrical dipole elements are considered. The …

This study introduces a novel method to reduce the radar cross section (RCS) of wideband
antennas. A novel wideband radar absorbing material (RAM) with frequency selective …

A wideband and compact microstrip grid array antenna is presented. The antenna is printed
on a dielectric substrate, backed by a metal board, and directly fed from a 50¿ coaxial cable …

We propose an optimization methodology suitable for the design of various antenna
structures. This methodology includes a rapidly-converging iterative scheme. In each …

This paper describes optimum antenna array structure for beamforming in smart antenna
technology. Different examples of array structures are analysed by the use of newly …

Antenna design problems often require the optimization of several conflicting objectives
such as gain maximization, sidelobe level (SLL) reduction and input impedance matching …

This paper presents a design of Wide-Band Microstrip Yagi-Uda antenna with high gain and
high front to back (F/B) ratio. Numerical and measured results of our design show more than …

Recently the social foraging behavior of E. coli bacteria has been used to solve optimization
problems. This paper presents an approach involving Bacterial Foraging (BF) to find …

A novel microstrip dipole antenna with wideband and end-fire properties is presented. It
employs a teardrop dipole and an open sleeve structure for wide impedance bandwidth, and …
