FREQUENCY RECONFIGURABLE ANTENNAS: A REVIEW PAPER

Abstract

In recent times, there is a high demand for wireless networks that can easily provide multiple access over a large spectrum and use the electromagnetic spectrum. The traditional antenna, however, does not fulfil the requirements of modern wireless communication systems. Therefore, a single radiating element called a reconfigurable antenna is built with the ability to adjust its features in real time. Reconfigurable antennas are categorised according to their antenna switching behaviour as a frequency, radiation pattern and polarisation reconfigurable antenna. The main purpose of this paper is to review numerous global publications on frequency reconfiguration patch antennas, which have greatly reduced the structural complexity and thus the size of the antenna.
