Modern era of wireless communication relies on the evolution of adaptive antennas. This
influences the new age antenna designs to adapt themselves to the changing RF …

Spectrum frequency is a valuable resource for wireless communication but very limited in its
availability. Due to the extensive use and ever increasing demand of spectrum bands by …

Reconfigurable antennas offer attractive potential solutions to solve the challenging antenna
problems related to cognitive radio systems using the ability to switch patterns, frequency …

A novel frequency-reconfigurable antenna is presented based on a circular monopolar
patch antenna. The antenna comprises of a center-fed circular patch surrounded by four …

In this paper, a novel wideband frequency reconfigurable patch antenna with switchable
slots (PASSs) based on liquid metal manipulation in 3-D printed microfluidic channel has …

A dual-polarized, tightly coupled dipole array (TCDA), delivering 13.1: 1 bandwidth, is
presented. The array incorporates a resistive sheet (R-Card) in the substrate to suppress …

A wideband, low-profile, tightly coupled antenna array with a simple feed network is
presented. The dipole and feed networks in each unit cell are printed on both sides of a …

A superstrate-enhanced substrate-loaded array (SESLA) with an integrated feed is
presented. The design allows for a practical implementation of the SESLA, a concept …

This paper presents a novel low-profile high gain frequency reconfigurable patch antenna
with unidirectional radiation pattern by using a grid-slotted patch with tunable varactors …

In this work, we introduce a conceptually new approach for designing frequency
reconfigurable wire antennas based on the use of multi-layered wrapping metasurfaces …
