Designing of Ultra-Wideband Microstrip Patch Antenna for WLAN Application – A Review

Abstract

As per the antenna theory, the main advantage of the microstrip patch antenna (MPA) is that it is small in size, suitable for flat and non-planar surfaces, and is simple to manufacture and low in cost using current printed circuit technology. Therefore, in this modern era, microstrip patch antennas are widely used in communication accessories. Ultra-Wide Band (UWB) technology is emerging as a promising solution to this problem. High data rates, large bandwidths and immunity to multipath interference are important features of UWB. UWB antennas must not create unwanted distortions and therefore good design is very important. This paper reviews the work done in this field to date and attempts to give an overall scenario of the research direction in UWB antenna design. This article has shown in the previous years of research that various antenna design methods in the ultra-wideband range, such as U-shaped cutting edge tapered grooves, DGS-based microstrip patch antennas, planar partially grounded patch antennas, and parasitic patch antennas, Fractal antennas and reconfigurable antennas.
