Here, the authors used a lumped port excitation for the Co-Planar Waveguide (CPW) feed. They used copper cladding for cutout and for substrate dielectric material named Arlon Cu Clad 217 (tm). The CPW slots and antenna shape acts as openings in a metallized plane. The antenna has been analyzed over frequency ranges of S-band (2.20-3.95GHz), C-band (4.90-8.20GHz) and X-band (8.20-12.40GHz). Their return loss, gain, directivity, VSWR and impedances have been compared. It is covered with air box depending on the minimum distance between the air wall and the radiating aperture at the starting frequency i.e., (9.375mm).
