Performance enhancement of planar antennas for WLAN applications

Abstract

In revolutionary wireless communication frameworks, achieving high newlinedata transmission capabilities is a highly coveted attribute, concomitant with newlinethe crucial requirement of integration with the prevailing communication newlineinfrastructure. This means that these antennas must possess the capability to newlineresonate at multiple resonant frequencies. The geometric parameters of newlinebroadband and ultra-wideband antennas can be manipulated to enable newlineresonance at single or multiple frequencies. Furthermore, this design strategy newlinecan be harnessed to augment the functional bandwidth of the antenna system. newlinePlanar antenna architectures are crucial in contemporary communication newlinesystems because of their miniaturized form, seamless integration, and multi newlinefunctionality. Several design approaches have been explored to facilitate the newlinedevelopment of multiband capabilities in planar antennas, including the newlineimplementation of fractals, metamaterials, loading slots and modified ground newlineplane structures. newlineDue to the necessity of meeting the demands of modern radar and newlinesatellite technologies, high-gain antenna development is being the subject of newlineintense investigation in current ages. Modern wireless communication newlinenetworks with high speeds are particularly suited for high-gain antenna newlinesystems because they provide a design topology that is simpler and easier to newlineconstruct than complicated feeding network-based array antennas. One newlineapproach that has shown promise for realizing large waveguide-dependent newlinecircuits on planar substrates is substrate-integrated waveguide technology, newlinewhich will enable applications using millimeter-wave and high-frequency newlinemicrowave radiation. newline
