Abstract
The proposed design of an antenna is a novel microstrip antenna array composed of metamaterial structures, in the form of closed ring, and unit cell resonators developed on FR4 epoxy (Dielectric constant = 4.2) substrate, which will operate in the Ku band useful for satellite communication purposes. The use of unit cell resonators allows us to operate at wavelengths of 2 cm or 20 mm, which is much larger than the diameter of the outer circle, which is 7 mm of the unit cell structure. The feed is directly connected to the four of the left-handed metamaterial structures’ circular ring resonators. The solution frequency has been set at 15 Ghz for optimum performance. The proposed antenna has a gain of 5.67 dB and the return loss of −26.33 dBi with a bandwidth of 1.2 GHz from 15 to 16.2 GHz. The design and the properties of this particular antenna have been studied and performed using the HFSS software, and the results have been compared with vertical array antennas placed at the center and the right side of the substrate.
