Crown square microstrip fractal antenna for wireless application / Amira Putri Mohammad

This paper presents the design of a crown square fractal antenna (CSFA) for wireless applications. This CSFA was fabricated on FR4 substrate with dielectric constant of er = 4.7 and thickness, h = 1.6 mm. All the design and simulation was carried out by using a commercial electromagnetic simulator,...
