In this paper, the authors present the design of Micro-Strip Antenna (MSA) with Circular Array of Square Parasitic Patches (CASPPs) on a superstrate layer for bandwidth enhancement. The antenna structure provides peak gain of 17.15dBi with impedance bandwidth of 950MHz (16.6%) which covers 5.25-5.875GHz ISM frequency band and 5.9-6.2GHz up-link C-band for satellite communication. High-gain and broadband performance is obtained by resonating MSA and PPs at different frequencies in 5.25-6.2GHz band. Results obtained verify that the proposed antenna structure is attractive solution for several wireless communication systems, such as satellite systems, base station cellular systems and point-to-point links.
