A reconfigurable antenna (RA) capable of steering its beam into the hemisphere
corresponding to θ∈{-40°, 0°, 40°}, φ∈{0°, 45°, 90°,-45°}, and of changing 3 dB beamwidth …

In this communication we present a concept of a partially reflective surface (PRS) antenna
capable of independent beam-scanning and beamwidth dynamic control. The beamwidth is …

A novel mechanism to obtain full-space electronic scanning from a half-space scanning one-
dimensional (1-D) Fabry–Pérot (FP) leaky-wave antenna (LWA) is proposed and …

A partially reflective surface (PRS) antenna design enabling 1-bit dynamic beamwidth
control is presented. The antenna operates at X-band and is based on …

In this chapter, we focus on the application of plasma structures to realize reconfigurable
antennas. Several approaches are presented to dynamically control the beamwidth and …

A novel two-state multi-lobe pattern-reconfigurable microstrip patch antenna (MPA) for wide
beam coverage is proposed, where two states are realized by two higher modes, and a multi …

In this publication, we continue our previous work on extending the angular scan range of
phased arrays using metasurfaces. We consider in detail scan enhancement using a single …

This paper gives an overview of our most recent research results on reconfigurable leaky-
wave antennas (LWAs), which have been developed at Universidad Politécnica de …

This paper presents an approach to simultaneous beamwidth and gain control in a circular-
polarization helical antenna using a truncated conical plasma reflector. Requirements and …

In the realm of health monitoring systems, wearable antennas play a highly important role in
facilitating global monitoring and seamless communication. This paper focuses on a …
