A compact monopole antenna has been presented with improved bandwidth for Ku-band applications. The proposed Ku-band antenna is made of rectangular slots and circular slots on the ground and the patch, respectively, by a microstrip line of 50 Omega. It is designed on a printed circuit board of 15 mm x 15 mmx 1.6 mm using FR4 as a substrate material. High Frequency Structural Simulator (HESS) is commercially available, which has been considered in this study depending on the concept of the Finite Element Method (FEM). 2.70 GHz (14.10 GHz to 16.80 GHz) is the achieved bandwidth of the proposed Ku-band antenna. The average gain is 3.66 dBi where 3.94 dBi is the maximum gain. The proposed Ku-band patch antenna exhibits smooth current distribution and durable nearly Omni-directional radiation patterns.
