Abstract: This article presents a mechanically frequency-reconfigurable monopole antenna and array that offers a wide tuning range, gain enhancement, and stable beamwidth. The monopole is positioned ...
Coral reefs are often described as biodiversity hotspots, but new research shows they also act as powerful regulators of the ...
Abstract: This study presents a comprehensive mathematical model for analyzing optimum frequency hop (FH) patterns (OFHPs) derived from two-dimensional circular shifts applied to a Golomb Costas array ...
