Jayasinghe, Jeevani; Uduwawala, Disala; Anguera Pros, Jaume (International Journal of Engineering and Technology, 2012, Vol. 1, 1, 2012)Designing multiband antennas with low volume becomes of practical interest for mobile telecommunications. This paper presents the designs of five small dual band patch antennas for GSM 1800 (1710-1880MHz) ... -
Genetic Algorithm Optimization of a High-Directivity Microstrip Patch Antenna Having a Rectangular Profile
Ayasinghe, Jeevani; Anguera Pros, Jaume; Uduwawala, Disala (Radioengineering, 2013. Vol. 22, 3 Setembre, 2013-09)A single high-directivity microstrip patch antenna (MPA) having a rectangular profile, which can substitute a linear array is proposed. It is designed by using genetic algorithms with the advantage of ... -
Nonuniform Overlapping Method in Designing Microstrip Patch Antennas Using Genetic Algorithm Optimization
Jayasinghe, Jeevani; Anguera Pros, Jaume; Uduwawala, Disala; Andújar Linares, Aurora (International Journal of Antennas and Propagation. 2015, 2015-01)Genetic algorithm (GA) has been a popular optimization technique used for performance improvement of microstrip patch antennas (MPAs).When using GA, the patch geometry is optimized by dividing the patch ... -
