Abstract: In this letter, a wideband two-dimensional (2-D) scanning multibeam array antenna is proposed using a novel beamforming network (BFN). First, a novel three-beam Butler matrix (BM) network, ...
Materials inspired by nature, or biomimetic materials, are nothing new. Scientists have designed water-resistant materials ...
Abstract: Circular array is a widely used omnidirectional scanning array. Nested array is a new variant of circular array. However, the traditional direction of arrival is not effective in estimating ...
