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 …

Directive pencil beams scannable in both elevation and azimuth are obtained through a
planar phased array placed inside a Fabry-Perot cavity. The key element of the proposed …

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 …

A new technique to implement fixed-frequency beam scanning using a half-width microstrip
leaky-wave antenna (HW-MLWA) is presented. The main beam direction is electronically …

In this paper, a holographic metasurface possessing beam scanning capability at fixed
frequency is presented. The desired radiation beam is obtained by using a reference wave …

A new type of printed periodic leaky-wave antenna is proposed, which is able to
continuously scan a beam from backward to forward endfire. The unit cell consists of a …

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 …

Although many directive antennas operating in a narrow band of millimeter (mm) waves
were reported, eg, antennas for 60-GHz wireless local area network (WLAN), their wideband …

Novel bandstop filters based on the defected microstrip structure with complementary split-
ring resonators (CSRRs)/half-CSRRs etched on the microstrip surface are presented in this …

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