Dual-band folded meta-inspired antenna with user equipment embedded wideband characteristics

User Equipment (UE) configured for dual-band operation comprising:

• an antenna;
• and
• physical-layer circuitry coupled to the antenna configured for communicating with an enhanced node B (eNB) simultaneously using a higher and a lower frequency band,
• wherein the antenna comprises first and second conductive layers disposed on opposite sides of a substrate to provide a wideband distributed structure comprising a plurality of high-Q resonances resulting from at least in part metamaterial-based loading, and
• wherein for dual-band operation, the plurality of resonances cause the antenna to operate as a folded monopole at a higher frequency band to cause current to flow in a same direction along the central longitudinal slot on both sides of the substrate, and operate as a slot-type radiator at a lower frequency band.

A dual-band antenna comprising:

• conductive material on a first side of a substrate arranged around a central longitudinal slot coupled with a plurality of perpendicular slots, the perpendicular slots including an upper slot, a middle slot, and a lower slot, the upper slot, the middle slot and the lower slot being perpendicular to the central longitudinal slot;
• and
• the conductive material on the first side including an inductive strip at a first end forming a shunt inductance, a transmission line region at a second end and a plurality of interdigital capacitors,
• wherein the lower slot, the upper slot and the central longitudinal slot form a dumbbell shape and
• wherein for dual-band operation, the antenna is to operate as a folded monopole at a higher frequency band in which current is to flow in a same direction along the central longitudinal slot on both sides of the substrate.
