Abstract: The inherent multiharmonic characteristics of time-modulated antenna arrays (TMAs) offer significant potential for generating multiple beams under a single radio frequency (RF) chain.

Laptops are practical because you can take them with you. However, laptops have a relatively small screen. If you work on a mobile computer, it quickly becomes annoying to constantly switch programs.

Abstract: Wideband multibeam antenna arrays based on three-beam Butler matrices are presented in this paper. The proposed beam-forming arrays are particularly suited to increasing the capacity of 4G ...
