A designation indicating that a phone supports two different frequency bands. Not meaningful without knowing which two bands and which technologies the phone will work with. For North American TDMA ...

Abstract: In this study, a compact dual-band multiple-input multiple-output (MIMO) implantable antenna system is proposed for cortical visual prostheses (CVP) devices. The antenna has dimensions of $7 ...

Abstract: In this paper, a wideband dual-circularly-polarized (dual-CP) antenna array which consists of dual-CP magneto-electric dipole (ME-dipole) elements at $K ...
