An improved ring resonator structure consisting of a capacitive coupling fixture is presented. Dielectric characterization is carried out using a fitting method that allows for comparison between measured and simulated results by setting a coupling l

This study presents the design and characterisation of a modified planar Luneburg lens antenna operating at 30 GHz. A parallel plate lens structure with varying separation between the metal plates realises the required variation of phase velocity of

This paper discusses a novel antenna concept for frequency reconfiguration by means of a simulation of a patch antenna simultaneously fed by two equal-amplitude signals. The frequency reconfiguration occurs by controlling the feeding phase leading to

Dielectric stepped-index flat lens antennas for operation at 12 GHz are presented. A brick-shaped dielectric with a permittivity profile optimized for focusing is sandwiched between the metallic plates of an open-ended parallel-plate waveguide. A tap

A millimeter-wave mobile communication base-station of compact form factor is discussed which could provide tens of users within a range of several tens of meters with data-rates in excess of ten gigabit per second (Gbps) for each user (that is, aggr
