This paper represents a simple parasitic rectangular patch antenna with variable shape ground plane, the ground plane is partial with slots on the upper part (connected to port) with circular parasitic elements. Designed of the proposed antenna on an FR-4 substrate material with permittivity 4.3 and 0.025 loss tangent and has dimensions of 20$\ast$20$\ast$1.5 mm$^{3}$. The impedance bandwidth of the proposed antenna is 145% (3.52GHz – 19.1GHz). The peak gain and radiation efficiency of the proposed antenna are 8.2 dB and 81% respectively in the proposed band of operation. The radiation pattern of the proposed antenna is stable for lower order frequency band with the fulfillment of omnidirectional characteristics. Due to simplicity and compactness, the proposed antenna is suitable for satellite communication (3-6 GHz and 7-9 GHz), defence communication applications and it covers 8-12 GHz (X-band). The proposed antenna details are described and simulated results are elaborated.read more
