This paper discusses a review of frequency reconfigurability through switches for 5G
applications. A new switching technique (varying values of lumped parameters) for …

Mid-air collisions (MACs) are commonly caused by temporary or permanent loss of flight
control resulting in catastrophic damages and hence must be countered with suitable …

A single-feed low-profile and easy to fabricate circularly polarized microstrip patch antenna
has been developed for GPS applications. For dual frequency operation, four slots are …

This paper presents novel low-cost single-and dual-band microstrip patch antennas. The
proposed antennas are realized on a square microstrip patch etched symmetrically with four …

This paper presents a compact dual-band slot antenna for 2.4/5 GHz WLAN applications.
The radiating elements of the proposed antenna are composed of a square ring slot and a …

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

This paper presents the design of a low-profile compact printed antenna for fixed frequency
and reconfigurable frequency bands. The antenna consists of a main patch, four sub …

This article presents a bandwidth enhancing technique using a modified ground plane with
diagonal edges, rectangular slot, and T‐shape cut for the design of compact antennas. The …

A novel frequency reconfigurable substrate integrated waveguide-interdigital capacitor (SIW-
IDC) antenna is presented. The antenna is designed based on a composite right/left-handed …

For the first time, the ionic polymer metal composite (IPMC) actuator is integrated with a
radio frequency identification (RFID) tag antenna for achieving frequency reconfiguration in …
