Millimeter Wave Beam Steerable/Reconfigurable Liquid Metal Array Antenna
Kelly, JR; Alqurashi, KY; Filgueiras, HRD; da Costa, IF; Cerqueira Jr, S; Xiao, P; Chen, Z; Wong, H (IEEE, 2018)This paper presents a mm-wave beam steerable/reconfigurable phased array antenna incorporating Eutectic Gallium Indium Alloy (EGaIn) liquid metal switches. The antenna operates at 26.2 GHz and has a scan range of ±58° which ... -
A Novel Approach for Designing Omnidirectional Slotted-Waveguide Antenna Array
Filgueiras, HRD; da Costa, IF; Arismar Cerqueira Jr, S; Kelly, JR; Xiao, P (IEEE, 2018)This paper presents a novel design of a high-gain omnidirectional slotted-waveguide antenna array for 5G mm-wave applications. The structure is based on a circular waveguide filled with teflon for manipulating its dimension. ... -
