Journal ArticleDOI
Increased Range Bistatic Scatter Radio
TL;DR: This work redesigns scatter radio systems and maximizes range through non-classic bistatic architectures: the carrier emitter is detached from the reader, and impact of important parameters such as the antenna structural mode are presented through bit error rate (BER) results.
Journal ArticleDOI
Application of a Comprehensive Learning Particle Swarm Optimizer to Unequally Spaced Linear Array Synthesis With Sidelobe Level Suppression and Null Control
TL;DR: The synthesis examples that are presented show that the CLPSO algorithm outperforms the common PSO algorithms and a real-coded genetic algorithm (GA).
Journal ArticleDOI
Improving Backscatter Radio Tag Efficiency
TL;DR: It is shown that amplitude maximization of complex reflection coefficient difference between the two states is not sufficient for optimized tag-to-reader backscatter communication, contrary to what is commonly believed in the field.
Journal ArticleDOI
Self-Adaptive Differential Evolution Applied to Real-Valued Antenna and Microwave Design Problems
TL;DR: A design technique based on a self-adaptive DE (SADE) algorithm is applied to real-valued antenna and microwave design problems, showing the advantages of the SADE strategy and the DE in general.
Journal ArticleDOI
On the Direction of Arrival (DoA) Estimation for a Switched-Beam Antenna System Using Neural Networks
TL;DR: A generic direction of arrival (DoA) estimation methodology is presented that is based on neural networks and designed for a switched-beam system (SBS), and can be applied to current cellular communications base stations, promoting the wider use of smart antenna beamforming.
