Accurate and efficient methods for beam-steering of holographic metamaterial antennas is of
critical importance for enabling consumer usage of satellite data capacities. We develop an …

A reconfigurable holographic antenna and a method of shaping an antenna beam pattern of
a reconfigurable holographic antenna is disclosed. A baseline holographic pattern is driven …

With the advent of 5G, software-defined radios (SDRs), and ultra-wideband systems, there is
a rapid rise in the demand for reconfigurable RF front ends. Conventional methods of using …

A novel liquid crystal (LC)-based holographic antenna (HA) with low sidelobe level is
proposed in this paper to achieve large beam scanning range and multi-beam scanning …

The design and characteristics of a PIN diode based tunable Frequency Selective Surface
(FSS) is provided. Spatial filtering, polarization filtering and polarization control are all …

A 1-D finite electromagnetic bandgap (EBG) periodic structure is studied. In the structure,
EBG behaviour arises from a unit cell comprised of a metallic patch sandwiched between …

A planar, metamaterial-based, one-dimensional periodic structure that can be switched
between multiple states is numerically investigated. It can be fabricated at low cost in gallium …

ABSTRACT A one-dimensional periodic structure comprising of eight unit cells each having
two metallic patches sandwiched between microstrip line and ground plane has been …

The effect of the biasing network (BN), formed by coplanar transmission lines (CPWs) built
into the ground plane itself, on the dispersion characteristics of a tunable unit cell (UC) is …

We introduce a novel structure of inhomogeneous parallel plate waveguide suitable for
advanced applications requiring frequency tunability. The structure relies on microstrip …
