Design and modelling of beam steering antenna array for mobile and wireless applications using optimisation algorithms. Simulation and measrement of switch and phase shifter for beam steering antenna array by applying reactive loading and time modulated switching techniques, optimised using genetic algorithms and particle swarm methods.
… work were to investigate, design and implement beam steering antenna arrays for mobile and wireless applications using the genetic algorithm (GA) and particle swarm optimisation (PSO) techniques as optimisation design tools. Several antenna designs were implemented and tested: initially, a …

Substrate integrated waveguide antenna systems
… focuses on SIW technology. Five di erent antenna systems are proposed to verify the advantages of using SIW technology. First, a novel K-band end- re SIW circularly polarized (CP) antenna system on a single layer printed-circuit board is proposed. A high gain SIW H-plane horn and a Vivaldi …

Digital Pre-Distortion: The Implementation, Minimisation, & Estimation
… of transmitter elements per base station and beam steering antenna arrays for high frequency communications. Power Amplifiers (PA) are a major cause for power inefficiency in Radio Frequency (RF) transmitters. An trade-off in PA design exists between efficiency and linearity. To satisfy both …
