The lens is constructed using dielectric-based unit cells made up of a glide symmetric approach. It is connected with a set of microwave detector integrated multi-port tapered rectangular feeds to convert the received RF energy from different directions to DC power across a combined load. The proposed structure can be a potential candidate to harvest ambient energy from a wide coverage range of around 160° and produce a power conversion efficiency of about 76% for an input power of 14.9 dBm at 24 GHz. © 2009-2012 IEEE.5G mobile communication systemsDielectric materialsDirective antennasElectric fieldsEnergy efficiencyEnergy transferLens antennasMillimeter wavesRectennasDesign MethodologyEnergyEngineered periodic structureGlide symmetryLuneburg lensMetasurfaceMulti-portPower transfersWireless powerWireless power transferRefractive index
