A broadband digital beamforming algorithm is proposed for directional filtering of temporally-broadband bandpass space-time plane-waves at radio frequencies (RFs). The enhancement of desired waves, as ...

In this article, a millimeter-wave bidirectional active integrated coplanar waveguide slot antenna with ball grid array (BGA) interconnection is proposed. Symmetric multistage step impedance resonator ...
