Metasurfaces have shown their great capability to manipulate electromagnetic waves. As a
new concept, reconfigurable metasurfaces attract researchers' attention. There are many …

Reconfigurable antennas change polarization, operating frequency, or far-field pattern in
order to cope with changing system parameters. This paper reviews some of the past and …

Reconfigurable antennas, with the ability to radiate more than one pattern at different
frequencies and polarizations, are necessary in modern telecommunication systems. The …

This lecture explores the emerging area of reconfigurable antennas from basic concepts that
provide insight into fundamental design approaches to advanced techniques and examples …

A dual-function slot antenna at microwave and millimeter-wave (mm-wave) band is
proposed. The design consists of a slot printed on the edge of the structure ground plane. A …

A new technique for designing dual-band reconfigurable slot antennas is presented. Dual-
frequency operation is achieved by loading a slot antenna with two lumped variable …

A new design approach for a microstrip patch antenna to achieve reconfigurable dual-band
operation with tunable frequency ratio is introduced. The approach uses a lumped capacitor …

In this paper we describe a method for optimizing frequency reconfigurable pixel antennas.
The method utilizes a multi-objective function that is efficiently computed by using only one …

A concept of a low-profile monopolar antenna operating in two independently reconfigurable
frequency bands is introduced in this paper. For the lower band, the design utilizes a center …

A frequency reconfigurable planar quasi-Yagi antenna with a folded dipole driver element is
presented. The center frequency of the antenna is electronically tuned by changing the …
