Reconfigurable antennas play important roles in smart and adaptive systems and are the
subject of many research studies. They offer several advantages such as multifunctional …

This paper presents a critical review of modern 4G, 4G/5G, and 5G antennas, which employ
PIN diodes and Varactors for polarization or frequency reconfiguration. For the reviewed 4G …

A wideband filtering patch antenna is investigated in this paper. The patch antenna is fed by
an F-shaped probe, which consists of one upper and two lower horizontal arms, as well as a …

A compact metamaterial inspired antenna operate at LTE, Bluetooth and WiMAX frequency
band is introduced in this paper. For the lower band, the design utilizes an outer square …

A novel shared aperture planar quasi-Yagi antenna with complementary pattern (as well as
polarization) diversity performance is presented for fifth generation (5G)-new radio (NR) …

A dual-band frequency-reconfigurable flexible textile and foam antenna with independent
tunability is presented in this letter. The proposed antenna operates simultaneously in a …

In this communication, the design and experimental verification of a reconfigurable circularly
polarized (CP) patch array antenna with frequency, radiation pattern, and polarization agility …

As the same device may be used for various types of applications, antennas must have the
capacity to perform multiple functions. Reconfiguring the polarization, operational frequency …

This article introduces a reconfigurable cavity-backed magneto-electric (ME) dipole antenna
array with agile polarization and steerable beam features for both linear and circular …

A reconfigurable dual-band antenna with pattern diversity is proposed. By switching the
dispersion curve of a composite right-/left-handed transmission-line-inspired structure, the …
