This paper presents a detailed review of multifunctional pattern and polarization
reconfigurable antennas, highlighting their potential to enhance performance of the wireless …

A single‐varactor frequency‐reconfigurable microstrip patch antenna is presented. The
antenna comprises a symmetrical arrangement of four metallised patches coupled and …

In this article, a miniaturized hybrid patch antenna is proposed that shows improved
matching bandwidth and almost invariant radiation patterns. This antenna consists of a …

A frequency reconfigurable microstrip transformed rectangular patch antenna consisting of
two slots able to radiate in S-band and C-band is proposed. Spectrum occupancy is first …

A compact high gain frequency reconfigurable metasurface reflector (MSR) loaded antenna
using a varactor diode is proposed in this paper. In comparison to a traditional antenna, a …

This chapter focuses on frequency reconfigurable antennas (FRAs). It discusses various
FRAs which are categorized based on how reconfiguration is achieved, and describes the …

In this paper, a frequency reconfigurable Vivaldi antenna with switched slot ring resonators
is presented. The principle of the method to reconfigure the Vivaldi antenna is based on the …

This thesis presents the feasibility of liquid metal in reconfigurable antenna applications.
Unlike conventional reconfigurable antennas, liquid metal possesses the ability to …

This paper explains why antennas can achieve limited frequency tunability by mounting
varactor diodes across slots. The reason is that majority of varactors have a resistance in …
