Abstract: This letter presents an optimization method for the design of a shaped-beam antenna array (SBAA) based on the method of maximum power transmission efficiency, addressing the limitations of ...

Asteroid impacts with global consequences are vastly rarer, especially compared to the frequency with which they appear in ...

Abstract: This paper presents a novel and insightful approach to beamforming a $2\times 2$ antenna array using the theory of characteristic modes. The array comprises four rectangular patch antenna ...
